Utah Seed Exchange 1st Annual Planting Festival will be on May 4th, 2013 at Allred Orchards, 2109 North University Avenue, Provo. There is no charge for this event thanks to the generosity of Allred Orchards, vendors, and class instructors. Times will be announced soon. This event is open to the public.
Here’s the jist of my seed starting (and grow bench).
1. A lot of people start seeds in something small like peat pellets and then “pot up” later. I tend to believe this is a waste of time (and resources). I start my seeds in a container suitable to the size of the finished plant right before planting out (at least I attempt to). True, I may have a few more issues with “dampening off” than others, but all in all, I lose pretty few plants to it.
2. I’m lazy. Being lazy requires some forethought (unless of course failure is acceptable and expected). Seed starting can involve planting, watering, fertilizing, potting up, turning lights on and off, etc. I automate everything as much as possible. Lights are on a digital timer, plants are self watering to the point that I only need to check/add water 1-2 times a week. Potting up I avoided as explained in #1. Details to follow.
3. I use the large Popsicle sticks for labels. This is not an optimal solution, but I’ve not found a better one yet. They’re cheap enough I can throw out, and easy to mark on. They’re also safe for my soil so I don’t have to make sure I have them all picked up at the end of the year. The drawbacks are that they break down a little faster than I would like, and, being a wood product, they can introduce organisms into the soil that increase the probability of issues like dampening off. I’d like a better solution, but simply haven’t found one I’m happy with so far. This works “good enough” for now
4. I use florescent shop lamps that take the T-12 bulbs for lighting. The government can whine all they want about how inefficient these lights are, but I purchased them for exactly two reasons: A. Light and B. Cheap. The T8 bulbs aren’t as bright, and I’m less concerned with saving electric and more concerned with making sure my plants get enough light. I use the 40 watt bulbs (this is about light, remember?) and bulbs with a color temperature of 4100K. It’s possible that different color temperatures may work better, but I did just enough reading to make sure I had something “in the neighborhood” and then went with what was available (and cheap). The lights and bulbs I get from Home Depot. The lights run about $10 each, and the bulbs I believe are going for about $20 for a box of 10. If you use the bulbs only for starting seeds you might consider reusing bulbs between years, but remember that florescent lights get dimmer with use.
5. I get custom lengths of chain to go on the lights. Raising and lowering the lights will be critical to successfully starting seed inside unless you’re planning to spend big bucks (and electric) on some high powered lighting. The idea is to keep the lights as close to the plants as possible because the strength of the light will drop off rapidly with distance. The exact lengths of chain you need will depend on your setup and the height of the plants you’re growing. 4ft is generally more than enough for my purposes.
6. You’re going to have to build a frame to support the lights. The frame can be made out of about anything. I used scraps of stuff I already had on hand. Had I been building new, I probably would have done it differently. I have found though that whatever your design, if possible, you want to have a smooth rounded surface where the chains from the lights wrap around as this will make it easier to raise and lower the lights. If you try some block of wood with edges, the chain will catch on the edges and be more difficult to manage. How pressed you are for space will also have a lot of bearing on your design. I utilized and existing wood bench that was a tad shorter than what I really needed. The result is that my lights butt together too closely at the ends and are spaced a bit more than I might otherwise allow. This gave me a prebuilt frame under the bench though and having two levels of lights allow me to maintain two different growing temperatures (more on this in a minute).
7. In general, seeds need no light to germinate – you can start them in the dark if you wish. However, the second they pop out of the ground, if they’re not getting sufficient light, you’re going to have a problem – a long leggy plant that is ill formed and likey to simply break off on you and die.
8. Seeds do tend to need heat to germinate, and some are VERY picky about their heat – enough so that germination will be very low (or not at all) without enough heat. Tomatoes and peppers in particular like it around 85F if they can get it. They’ll definitely germinate with less, but they’ll take longer and germination will be lower. You should make a digital thermometer part of your setup so you know what’s going on. I prefer one with indoor and outdoor settings (and hence a probe for outdoor) and I’ll put the probe in the water as with my setup, the water temperature will pretty much be the same as the temperature at the root zone and plants care a lot more about the temperature of their roots than they do the temperature of their leaves. How warm it is also tends to have a pretty heavy impact on how quickly your plants grow. The warmer it is, the faster they grow (you don’t want it warmer than whatever may be appropriate for the particular plant you’re growing though). If you’re going to grow in a colder area (basement or garage?), then you should start your seeds earlier than recommended so that they have time to grow to sufficient size.
8. I tend to use a good potting soil for my growing – something with built in fertilizer so the plants get a good start and I don’t have to worry about adding fertilizer until later. I’ve found that despite how long the bag claims the fertilizer will last, it doesn’t – possibly due to how I water. As a result, I watch the plants and when the growth seems to be lagging or the color is a bit bleached (can also happen if the plants aren’t getting enough light), I’ll add some liquid fertilizer to the water the plants get. I try to use a balanced low powered fertilizer, and I typically use less than whatever the recommended amount was. Growing your plants too quickly with large amounts of nitrogen isn’t good for them. It impacts the plant’s ability to take up other nutrients it needs, and even without the impact, other nutrients may not be available in sufficient quantities for balanced growth. High nitrogen plant growth is more attractive to aphids, leads to a weaker plant, and can lead to blossom end rot in peppers, tomatoes, and other plants (Yes, blossom end rot is a calcium deficiency, but there is almost ALWAYS enough calcium in the soil – the excess nitrogen is simply making that calcium unavailable to the plant in sufficient quantities. You don’t fix the problem by adding calcium, you fix it by cutting back on the fertilizer and/or leaching out what you already used).
9. Watering – the big trick. When watering, your plants can never have to much water. They can have a lack of oxygen at the root zone which is what really causes the issues people blame on to much water. I’m not trying to make my plants live in water though, so I don’t need to watch my dissolved oxygen levels in the water. To water the plants, I use 18 ounce plastic drinking cups. I take a stick pin and poke holes in the bottom edge of the cup (not the bottom – the holes are on the side), all the way around the cup. I fill the cup with soil, and then place the cups in a plastic bin/tray/tote/whatever that is capable of holding water. I’ll then gently (so as not to compact the soil any more than I have to) pour water in the cups to start the wicking action. From there I’ll pour water in the container holding the cups until I have around an inch or so of water. You’ll generally want to do this at least 24 hours in advance of when you want to plant. Leave it all sit and check the next day to make sure the soil at the top of the cups is just slightly moist (the soil will draw the water up through the cup – and it draws up the perfect amount. Not to much, not to little). If the soil at the top is dry, then either you need to let it sit longer, you didn’t pour enough water down through the cup to get the wicking started, or you forgot to poke holes in the cup (or possibly didn’t poke enough). When adding the soil to the cups, do try to make sure you don’t have “lumps” as large air spaces in your growing medium will interfere with the wicking and your plant roots won’t appreciate it. Once the soil at the top is appropriately damp, you’re good to plant. Just make sure the water level in the container with the cups never drops down lower than the holes in the cups. If it does, and your cup has gone dry (and the plant isn’t dead), you’ll want to pour more water IN the cup as well as the container holding the cups to insure the wicking action with the water starts up properly again. When you need to fertilize, you can pour liquid fertilizer directly in the container holding the cups. Just stir the water up some to make sure it’s dispersed well, and don’t use very much – you can always add more later, but if you use too much, things may be dead before you can fix your mistake. If you do use to much (and things aren’t dead), do a complete water change in the container holding the cups, and then flush the cups themselves with water as water is good at leaching away nitrogen.
10. Heat – I grow in a cold area (my basement) and I’m cheap so I like to get all of the bang for my buck that I can out of my lights. I use a a few layers of a thick black plastic (also purchased from Home Depot over in the painting section) to completely cover the upper section of my grow table. Because it’s black, light hitting the plastic is converted to heat. Because it’s covered, the heat tends to stay inside the plastic (heat rises). Because it’s layered, it’s more effective as I’ have air trapped between the layers which help with the insulating effect. This also captures heat given off by the lights because they’re not 100% efficient in converting electricity to light. In addition, since this is the upper section of the table, some of the heat generated by the lights below the table will rise up through the table to provide additional heat. With no heating other than the lights themselves, I can often maintain a 20 degree F temperature difference between the temperature inside and outside the plastic – so if it’s 55F in my basement, it’s 75F where the plants are – not bad. Due to this, I’m also prone to check on my plants by sticking my head under the plastic instead of raising it up which lets a lot of the heat out. This has one drawback. It’s not a problem for me, but may be a problem for you depending on where you do it. Due to the temperature difference, and the humidity under the plastic (remember all of that water in the plant trays?), you’re going to have a lot of condensation forming on the plastic and running off. The floor is going to get a bit wet sometimes.
11. Growth – as my plants get older (and taller), I tend to move them to the lights under my grow bench. This gives me room up above for new things I need to start, and it exposes the plants to colder air. This helps to slow their growth so they don’t get to big before I plant them out (you don’t want them root bound), and it also helps start the hardening process (you’ll still need to harden them off outside in the sun/shade).
12. Strength – if you live in an area that is sometimes prone to high winds, you’re going to want to try and make sure your plants get some wind (preferably from different directions) before planting out. Wind (gentle) will cause the plants to form stronger stems than they otherwise would so that hopefully the winds outside won’t just snap off the tops of your plants on you. An oscillating fan seems to work best for this. It’s not something you have to do, and you don’t need to do it the entire time you’re growing if you do (I tend to just do it towards the end), but it does help. Also remember, if your plants aren’t getting enough light, they’re naturally going to get leggy, and that tall growth is _NOT_ good growth I don’t care how tall it is. It’s a good way to kill your plant. You’ll want to keep the lights as close to the plants as you can, but the closer they are, the more often you’ll need to check them. These bulbs are cool enough that they won’t burn your plants (or you) like the high powered bulbs do – however, if your plants get to close, they’ll grow up around the bulbs in some weird growth you don’t want and you may have to take the bulbs out of the light to extract the plant.
Here are some photos:
With 05110016.JPG in particular, that shows seedlings that didn’t get enough light. The ones towards the front aren’t too bad (notice the darker color), but the fact they’re leaning like they are is a clear indication they’re trying to reach a brighter light source elsewhere. The ones in front might be decently saved. The ones in back are already too far gone to make it worth the risk of attempting to save them (assuming you still have time to start new ones). I don’t advocate attempting to use a window for light. While I suppose someone somewhere may have a window with enough light (and I’m positive it’s south facing if they do (assuming they’re in the northern hemisphere)), I have yet to find one.
Those images were resized because it seems no one really cares for or is equipped to handle high resolution photos. I can provide them in their original resolution if that’s of value to you.
If you have questions, feel free to ask, I’m happy to answer.
Do to unforeseen circumstances February 28th’s meeting and class have been cancelled. For those of you needing basic information on starting seeds Homestead Lady has given me permission to share this here:
Seed Starting Basics
by Homestead Lady on February 19, 2013
I know this is all over the blogosphere right now (which is so awesome!!) but I just wanted to add my two cents about the value of learning how to start seeds indoors in early spring and again in late summer – or really any time!
First, you’re saying, I’m busy and already know how to keep a garden, why do I need to learn how to start my own seeds indoors? You are busy and you are already a very good gardener but here are a few things to consider:
- Starting your own seed allows you to expand you garden palette. There are some very fine nurseries with some very fine offerings but even the best don’t always provide that one variety you’re looking for. If you’re interested in seed saving, especially, being able to pick and choose what variety you’ll grow out is vital. Even those gardening with hybrids may get tired of the same five tomato options and the same three pepper varieties.
- Starting your own seed can be economical but this comes with a caveat; after you’ve spent some initial capital, the yearly cost of seed and some kind of growing medium is minimal. This becomes particularly true if you’re gardening on a large scale. If you’re growing on a balcony, buying a few nursery starts probably won’t break you but if you’ve got a larger space, particularly if you’re feeding a lot of people, you may discover a large savings come planting season.
- This skill is vital if you want to be as self sufficient as possible. If you have a desire to be able to grow your own food from start to finish, seed starting is something you want to make sure you know how to do. This skill will probably also lead you to learning how to save your own seed; the height of garden self sufficiency! Over the years, the number of seed houses has shrunk, we’ve experienced numerous seed crop failures at home and abroad and GMOs keep turning up in various seed strains despite the concerted efforts of heirloom growers like Baker Creek and many others; in short, its time we took control of our own food and became responsible for protecting seed on this most basic level. You can’t get any more homegrown than your backyard and its vital we know where our seed is coming from!
Well, then, how hard is this going to be?
- If you’ve ever made a peanut butter and jelly sandwich AND kept a pet alive, you’ll be fine. The following is a step by step guide to starting your seeds indoors; at the very end are some links that might be helpful.
- Mostly I want you to know that you CAN do it and be successful at it; there will probably be some trial and error but isn’t that the essence of gardening? Sometimes our failures are just as instructive as our successes!
Starting your seed indoors
- Gather your supplies: Quality seeds, planting medium (“soil”), container with drainage at bottom and some kind of cover, water, labels for the trays, somewhere to put the seed tray (we got our rack at Costco. Your containers don’t have to be fancy – one of my favorites are the spinach boxes from Costco with holes punched in the bottom. As you see here, we also have old Tupperware, strawberry boxes and plastic/paper cups (I actually prefer these for potting up tomato seedlings because I save the collar of the cup and plant it with the tomato to protect against cutworms – nasty buggers!). If you need to, wrap the bottom of particularly open boxes in aluminum foil (not a big fan of using this for much else) to prevent water leaking out in torrents. If your lid isn’t solid but has air holes, you’ll need to wrap that at first to create your little greenhouse for germination; I like to use Press N Seal because, unlike Saran Wrap, its easy to use, seals easily and can be reused. If you have these black grow trays, decide whether you want the individual cell packs or just flat trays. I like open trays because, using a sharp knife, the seedlings are just as easy to get out and pot up as with the cell packs. The cell packs break and the bottoms punch through pretty easily; plus, they just annoy me for some reason. You can also make your own paper pots, use a soil blocker (those are awesome and I highly recommend them) and/or use any biodegradable pot or pellet start you want. Figure out which one you like working with and use that.
- After the seeds germinate, you’ll also need a light source (a fluorescent shop light from someplace like Lowes works just fine). If the air circulation in your designated spot isn’t great, you may need a small fan, too. You will probably want some kind of heat mat or Christmas light set up underneath your seed trays to increase both the amount of seed that germinates and how quickly the seeds germinate. Remember what I said about the peanut butter and jelly sandwich? Once you get all your ingredients, the genius is in the mix – if you properly mix your peanut butter and jelly before you put it on your bread, there’s less mess and your lunch is a happy event; skip that step and you end up with jelly on your tie. Get all your ducks in a row and take time with your set up; there’s a proper mix you’re going for here. Once you get the foundation laid, seed starting is a lot easier do successfully.
- Mix you planting medium with enough water to look like brownie batter – not so wet you can squeeze water out of a handful but not so dry you have pockets where there’s no water at all. All seed starting literature will tell you to use a soil-less medium that you can purchase fairly easily at most garden centers and nurseries; these consist mostly of peat moss. The reason for using this medium is to prevent disease; potting mixes and regular garden soil usually play host to a myriad of bacterias and pathogens that might be relatively harmless to a transplant or full grown plant but that can wipe out a whole tray of seedlings. I use soil-less medium all the time but also occasionally use a quality potting soil that includes peat moss. Quite frankly, I don’t want to rely on some specialized product that I’m forced to purchase all the time. If all you have is garden soil and you’re worried about disease, you can heat your soil in your oven on a cookie sheet to kill the gunk. I don’t have space in my garden for plants that have to be babied overly much so I don’t worry about it. I make sure my growing medium is as clean as I can make it that year, I make sure I keep good air circulation while my seedlings grow and I make sure to give them some nice fish emulsion every now and then and everything works out just fine.
- Pat your soil into your container; don’t mash it, just pat it politely in and read your seed packet to figure out how deep to plant your seed. Some need light to germinate and so you’ll simply scatter the seed on top of the soil and others need to be planted at a certain depth. Once your seed is in, sprinkle the surface with organic cinnamon powder to prevent damping off (a fungal problem that can attack emerging seedlings and looks a lot like spider webs – most people use soil-less medium to prevent damping off since once you have it, its hard to get rid of). Then cover your container with either a lid or with the Press N Seal or whatever you have on hand. Bear in mind that some seeds need light to germinate (so make sure your lid is clear) and some need dark to germinate (so make sure your lid isn’t transparent). The reason to cover your damp seedbed at this point it to keep the moisture and heat inside the tray to encourage germination – like a little greenhouse.
- Place your newly planted trays on your heat mat, on your rack and monitor over the next few days. Some seeds take a few days to pop up (lettuce) and other can take many weeks (a lot of perennial flowers and herbs can take this long). Some may surprise you – I planted chocolate daisies this year and the packet said to be prepared to wait for several weeks before germination but they popped up after only four days! Once your seedlings begin to emerge from the soil, remove the cover to expose the seed trays to air circulation to prevent disease and encourage the seedlings to start getting taller and stronger.
- Now’s the time to turn on your lights! Set up your lights so that they’re adjustable, up and down. While your seedlings are just popping up and tiny, keep those lights right over but not touching their heads; as they grow, pull up the lights to keep the seedlings moving straight up. If your lights are too high above your seed babies, they’ll get leggy, weak and fall over in disgrace.
- Once your seedlings have developed their first and/or second set of true leaves, you can transplant them. You’ll want to do this as soon as you can so that the roots have more room to grow in a larger container. That larger container can just be a plastic cup – whatever, it just needs to be bigger. When transplanting, be sure to lift your seedlings by their leaves and not their stems; leaves will recover if you damage them, stems once pinched, die. No forgiveness.
- How long your seedlings stay in your indoor nursery just depends on the weather and when your life allows you to get them planted. Remember the part about keeping a pet alive? Yeah, now’s the time to tap into those skills. Caring for baby plants is like caring for baby anything – they need constant water and food, light, air and space. You’ll want to run your hand over them once a day to toughen up their stems and interact with them. Make sure you speak or sing or visit with them in some way every day; no kidding, but they’ve done studies on this and you will enjoy greater success if you’ll take a minute to be nice to your plants. I could give you a long lecture on energy and light and positive/negative auras but I’ll resist.
- Before you plant your babies outside, you’ll need to slowly acclimate them to outdoor conditions. This is usually where I mess up because it requires remembering details. You’ll need to put them out in the sun for an hour or two one day and then a little longer the next day. You have to make sure its not too hot and not too cold and keep the babies hydrated. Again, I don’t have time for sissies and so often what happens is that I put my seedlings out in the sun the first day and bring them in when I remember them. By day two, I’m bored with the process and leave them out all day and, if it’s not too cold, I’ll just put them in a safe place outside overnight or shove them in the garage. The next day I’m usually putting them in the ground. I do lose a few now and then (one time the turkeys got a whole flat of onions because I simply forgot they were out!) but this lazy system works for me just fine; I do feel compelled to say, do as I say, not as I do.
- Remember, once you get really going with your seed starting, you’ll have new babies coming up behind older seedlings and you’ll need to make space and time for tending them all. If this is your first or second year starting seed indoors, I recommend you only start with a few varieties. Start some onions or lettuces for cool season crops; start some tomatoes and peppers for warmer season gratification. Don’t take on too much your first few times; make sure you grow something you love to eat.

Excellent article/excerpt on permaculture plant guilds by Toby Hemenway. This excerpt comes from the author’s book Gaia’s Garden.
From the Redeemed Gardener – this explains how to encourage worms in your garden beds by creating a little buffet section for them. Easy and inventive – I say it all the time, people are so clever! ~ Tessa
Great video about permaculture. This is what it says at Growtest.org, “This video, whose aim is to inspire people to start their own permaculture projects, shows how permaculture is practiced in four very different settings: a backyard garden, an urban community garden, a co-op restaurant garden, and a small farm.”
An excellent article from Good Magazine about the positive impact the local food movement is having on race relations and cultural diversity in the US.
