Seed Starting: Ghetto Greenhouse

Growing from seed can be rewarding and a cost effective way of expanding your garden. Depending on the plants it can often times be cheaper than buying a plant at your local garden center. While big box stores can be cheaper than buying at a specialty nursery sometimes the variety of plants can leave a lot to be desired. To avoid the "McGarden" look, acquire seeds; on-line, through catalogs, seed exchanges and the seed rack of your favorite store and start them yourself.

You're probably thinking that you couldn't start seeds yourself because you don't have the money for seed starting trays, grow lights or most importantly- a greenhouse. Fear not, using this method all you need is some space outdoors. Here's what you need: an empty 2 liter plastic bottle, potting soil, a handful of seeds and a tool for making holes. I find that Miracle- Gro potting soil works fine for me, other people don't like it for starting seeds. Use your favorite brand but whatever you do don't skimp on the soil. If you use those 99 cent bags you find in Walmart, Walgreens or similar stores it may harden and you'll end up with a brick. That's fine if you want to build a patio or raised bed, but not so good for seed starting.

Take your 2 liter bottle that you've cut in half and make several drainage holes in the bottom of the bottle.

Fill the bottom with about 4-5 inches of soil. Read the seed preparation directions on your packet of seeds and sow them and water them in. You can water from the top or set the "pot" you just made in a saucer of water and allow it to absorb water. Take the top half of the bottle and replace it. What you have now is a seed starting greenhouse like the kind of available in stores. But it didn't cost you between 12-20 dollars. It should look something like this

I use this method to start seeds that require Stratification (cold treatment) I prepare all of my Ghetto Greenhouses and sow the seeds and set them outside for the winter and allow them to be exposed to the elements. When the weather starts to warm up and the snow melts I keep an eye on the containers and water when necessary. The clear bottles make this easy and when the seedlings emerge I just plant them out either into the ground or into pots. I can fit five of these into a plastic milk crate that I stack in a corner of my back yard. Here's what it looks like inside in the spring.

You can use this method to start all kinds of seeds. When the weather outside warms up you can start your tender plants, like annuals and tropicals. You can also adapt this method and make your Ghetto Greenhouse out of things you may have around your house. As a kid my grandfather used coffee cans, in school we used empty milk boxes and larger orange juice boxes. You can use take out containers, the salad containers you get nowadays in fast food restaurants. If you have empty pots you can cover them with plastic wrap or used sandwich bags. You can sow your seeds in Styrofoam/plastic cups and set them inside a plastic tote. Just make sure you have drainage holes and some opening(s) for ventilation, a few holes in the top of your container will still trap enough humidity. If you don't have a yard, try your deck or a bright windowsill.

On the right hand side of this blog you'll find a link to a great site with lots of info on individual seeds and their germination requirements.

Thank you! This tutorial held some very valuable information for me.

Garden Girl said...

Now what a contradiction...New Years Resolution 1: Grow more plants from seeds to save money. New Years Resolution 2: Drink less soda. See what you've done :)

Great advice though...and Im now officially link happy with everything I've stolen from your side bar.

Hmmm...bottle water greenhouses....

MrBrownThumb said...

aimzee, Glad to hear.

garden girl,

LOL. You don't have to drink the soda all you need is the bottle.

Good for you for introducing some new people to WSing!
It's one of those 'too good to be true' sort of things, so most people figure it won't work because it's too easy - until they try it.
Good luck with this year's.
:)

I came across this example on flickr of using the soda bottle greenhouse. Seriously I think it's great and I don't think I would have thought about turning it on it's side like BK did.

BK is also creative enough to use egg shells to start some pineapple seeds. Check out his flickr pics that he allowed me to link.

Thanks for visiting my blog Mr Brownthumb. It's very rewarding growing plants from seed, thanks for no frills tutorial. It really is something anyone can do and get enjoyment from.

Leslie said...

I just found your blog when straying from a site on Garden Voices...I'm enjoying your writing and have linked you on my blog. Looking forward to future posts!

MrBrownThumb said...

Thank you Leslie. I'll add you too.

That is such a great Idea, I'm am a bit thrifty and would never buy one of those seed starters, But i work at a place that sells this fancy "bio dome" seed starter. That I did purchase as a gift. But I would never buy it myself.

MrBrownThumb said...

tgentry thanks for visiting. Isn't it funny how we're "thrifty" but we don't mind spending money on items like that for other people?

I like your avatar and checked out your blog. You should post more and take advantage of that new camera you got.

Monique said...

I am a very new gardener on a tight budget and I love your interesting soad bottle idea. Thanks!

Have you ever used 1-liters (I have tons of them and no 2-liters at the moment), or is the opening on the top too big relative to the container to have a greenhouse effect?

And one last question: am I reading this wrong, or do you really put the bottles right outside in Chicago winter? I'm in the Boston area and can't imagine putting seeds outside in the next few weeks!

MrBrownThumb said...

Hi monique

Yes I put them out in the middle of winter here. Some seeds need stratification meaning they need to go through a freeze thaw cycle to break dormancy. So I put out all of those out when it's really cold. But in a couple of weeks you can put out your more tender seeds like annuals.

And of course you can use the 1 liter soda bottles. Since they're smaller you can use them for smaller amount of seeds and you can fit more of them in crates when you're setting them out.

If you want you can tell me what kind of seeds you have and I'll see if I can tell you if you should do them now or wait.

Ghetto greenhouse :). I have been using those for years and didn't even know it!

Pcrucifer said...

And here I thought I was being original starting seeds in a milk jug and cake dome. Neat stuff. I enjoy reading your blog> I've live in urban areas most of my and am trying to adjust to small town life. I have a neighbor who gives his toddlers rides on his motorcycle around the house. Small town America has character too.

pccrucifer,

Thanks for stopping by. I think we all think we're being original but it is funny to see how many of us all think alike.

I've got a new post on seed starting:

I love this idea! I am always looking for resourceful ways to use things around the house instead of expensive gardening gear, partly, I think, because I grew up in a household whose parents lived through the depression.

I use those clear plastic boxes with lids (the ones organic greens come in at the grocery store) in very much the same way, but you lose the benefit of the tall top which your method provides.

Thanks!

Amber said...

I used to do those all the time as a kid, and just let the plant grow in the bottle until it died. Now, I used this method again this year, but had a LOT of trouble when I tried to transplant the seedlings. Any advice for transplanting?
