Seed Starting: a Comparative Study on Cheap Indoor Methods

Seed Starting: a Comparative Study on Cheap Indoor Methods
In this instructable, I will offer instructions for making, and discuss the pros and cons of, 5 cheap methods of starting seeds indoors:

(1) Egg cartons
(2) Toilet paper tubes
(3) Milk cartons
(4) Yogurt cups
(5) Peat pots and coco fiber pots

The seeds that I start using these methods include peas (climbers, like other legumes), tomatoes, peppers, and eggplants (nightshades), corn, basil, thyme, parsley, and marigolds.  Since I live in an area where we can get snow into mid-May, it's important for me to have healthy, well-started seedlings by the time we're frost free so that my plants have enough time to mature and produce veggies.

Step 1What You Need

Take a look at the various starters I've used and decide which ones best suit your needs.  In addition, you will need:

- seed starter mix: it's not that expensive, and superior to potting soil because it's fine and uniform.
- water: I never use plain tap water, because it's chlorinated.  At the very least, I run it through my Brita.  If you have distilled water, that's the best for watering plants.
- something to mix your dirt and water in (I used the bottom half of a gallon jug)
- a latex glove: optional, but dirt dries your skin out and I don't like that, so I wear a glove on my dirt hand.
- seeds.  I like heirloom seeds and buy them from Tomato Bob's website, where they have varieties on sale for twenty-five cents at times.  But the local hardware store or gardening store sells seeds too, and there ain't no shame in that.

That's it.  Do this outside on a mild day, or be prepared to clean up dirt inside.

Nice instructable. This year, I was so loathe to start seeds inside (I have small children and cats) that I just started them all out of doors, using plastic bottle cloche's to protest the tender ones (tomatoes, peppers, etc.) So far, so good, they have survived 45 degree weather.

Have you tried the seedling pots you can make out of newspaper (found here on Instructables)? Curious as to your take on them.

I tried one round of the newspaper this year. I was unsuccessful for other reasons than the fault of the pots. I put them together as instructed on here somewhere, with staples, because they wanted to unroll otherwise.
Pros: cheap compared to most alternatives, customizable size, and you bury the pots in the ground!
Cons: They are fairly flimsy when wet. If you're careful when handling, they shouldn't fall apart on you. Although, they will not stand up to being dropped and or eaten by the dog...

Alternatively, I am trying paper beer bags (from a gas station) They seem to hold up better than the newspaper and are not so much of a pain to put together. Plus they are fairly cheap. The brown ones would have low die levels by my guess, and would be pretty safe for this use.

Excellent. Wish I'd read this earlier this year! I have several seedlings growing in egg cartons, and yes, they're being stunted by the limitations of the container.

Now I just need to find someone who eats a lot of yogurt. :D

I love seeing comparisons, thanks for taking time to post this. I'm doing carrots in TP tubes so they needed to be full length but f course, that has meant black mould- eugh.

I always lose my notes about which seeds I planted, what dates, how long they took to germinate etc. so I now use a free online garden tracking site which I'm now addicted to, I can see when everything was planted, how many days it took to germinate/sprout/flower/harvest etc. and you can make journal notes for each plant which is great when you are doing comparisons or being a bit experimental. They also have tons of additional features for supporters which has been totally worth it for me. I'm growing more seeds this year than ever before.

You wouldn't want your little seeds bathing in chlorine so it's better to use rain water instead of using tap. Wonderful instructable..I'd try the egg cartons and the tissue paper rolls next time!

Chlorine evaporates out of tap water very fast, simply refilling your water can immediately after watering (so that it has at least a day to sit) will remove all the chlorine. I agree that rainwater or non-chlorinated tap water (I wish I had well water like my parents do) but it's not always possible to collect enough rainwater to water your plants and unfortunately in some places it's actually illegal.

Why don't you try it without the container? Soil Blocks are easy and work really well: http://www.instructables.com/id/Make-Super-Cheap-Seed-Starters/

This won't be for everyone, but: if you are given a bunch of those cute melted record bowls that you don't really know what to do with (as I was last Christmas), they make excellent seed starters for bigger sprouts (corn, zucchini, etc.). The hole at the bottom gives a little bit of drainage, and they're generally deep enough that you get some good strong roots.

Very nice instructable, this will help me and my seedlings a lot

I make tubes from part of a sheet of newspaper rolled around a cylindrical form (2" pipe, filled pop can, plastic bottle) , stapled along the side along the top and on the bottom, and then filled with potting soil. It's not self supporting, so I usually put as many of them as will fit into a plastic crate. Later, when the plant is ready to to go into the ground, I slice up the paper a bit so make sure the roots aren't blocked. The benefits: I can make them any dimension I want (just have to find the right form); the tech scales well (not limited by the amount of toilet paper you've consumed that year).

It's not perfect, but it is cheap.

On the commercial end, I have some folding air pruning things. Flimsy, only lasted a few years, but they work very well.

Great instructable, you have quite an indoor garden.

Hmm, did you wash the milk container before you planted the seeds? I wonder if that had anything to do with their awesome growth.
Apr 2, 2011. 6:26 PMJohenix says:
The trace of milk would add traces of calcium, phosphorus and nitrogen.

Great info, I will be benefiting from it this year.Thank you!

Great instructable! This helped me out so much with starting my seedlings, thank you.

Rather than cutting the TP tubes in half, leave them whole and I have found you can plant beans and peas without a problem. They seem to appreciate being able to grow long roots. Much cheaper than the fancy "root trainers" you can spend a fortune on! Creative idea for tray to plant them in. Another idea is to use margarine-type tubs, or you could cut the top off milk/juice containers.
