I'd really like to know how long, on average, a single "serving" of water will last for. I'm going away for a few weeks and need a way for a few spearmint plants to survive without me.

I was wondering if the cotton string goes all the way to the top of the dirt so all of it gets watered or does it work that way? What kind of vegetables can you grow in a small container like this?

In mine I do not have a string that goes to the top of the soil. If the soil is good for plants, it should draw water up the same way the string does, but moreso, because it should have more water potential.
Jun 30, 2010. 1:21 AMxACIDITYx says:
If the plant is supplied with water directly, it will not have much of a need to stretch out its' root system. So having the string extending only a little bit up through the soil rather than the entire way up should, in theory, encourage growth of the root system of the plant because it will have to grow outwards to obtain the necessary water.

to put water back into the lower part of the vase, is there a way to do that besides having to take out the plant each time?

I had everything i needed within about 5 feet. I read this, and made it in about 10 minutes. We had bought a cheap mop with the cotton strings on it for the wicks in our tiki lamps. That worked well, just had to make the hole a little bigger. Thanks for the fun idea. When my kids are older we'll do this together.

I don't have cotton string, so I cut up an old white cotton t shirt into long, thin strips and used those, as seen in this instructable:

Giving this a go. Planted some Columbine flower mix. If some of you are new to gardening like I am try out gardenguides.com, helped me out quite a bit and very informative.
Jul 21, 2009. 1:53 PMThe Dark Ninja says:
One note I want to point out here... Columbines are a very picky and difficult plant to grow. From the time I posted this article until about a week ago the plant seemed like it was going to die or fail. But just last week it bloomed it's first flower. Very awesome. While the wicking method described here did NOT work using EMBROIDERY FLOSS, I do believe it will work as described in the instructable with COTTON string.

By "role", you mean hole, right?
Jun 12, 2009. 6:26 AMiancremona says:
Great method! Here emotioned.com has a similar way to do it, it's done by resizing a pot with minimal tools (and does not contain any PVC). 5 stars

Does it have to be COTTON? Or can it be a wool string?

does it have to be string? can i use that thin clothsline type cotton rope/ line stuff?
Mar 29, 2009. 2:34 AMcanno says:
great idea 5/5 very simple will having more strings affect the moisture and will thicker strings affect it too

Thanks you so much! I used this in my Biology project! I was so excited!!
Feb 27, 2009. 12:33 PMHegpetz says:
This is an awesome idea! Thank you very much for sharing!!

I. Love. It. Excellent design. 5 stars, and I don't give those out lightly.

If you add a nutrient solution you also have a basic in soil hydroponic system. Ive used a similar method with fantastic results.

Nice instructable, I really like it. How well do you think the plants will last in a rather chilly dorm room? I tend to keep the temperature around the high 50's to low 70's. It's usually in the 70's and 60's tho. Does anyone recommend any plant in particular? Flowers are nice, but a more practical plant would be nice too. Thanks.
Feb 4, 2009. 3:31 PMsurfreak says:
If you keep the temp around 70 (F), both pothos/devil's ivy and chinese evergreen are great plants. They're extremely hard to kill, i.e. great for dorms. Can't let it get too cold, though. They love low, diffuse light, and water once a week. If it's not too humid where you are, look into a humidifier or mist them regularly.

I've made plenty of these, and they work great! I usually use a 2-liter bottle. I always put a hole in the bottom bottle a lil' high up so I can add water, instead of removing the top bottle.

Great idea! I had a teacher that used this idea to draw the leaky roof water into a garbage pale! I am going to try this and share it on my show too! Will link back to you.

HAPPY GARDENING!

excellent idea

u got great ideas..... like it best regards

I love this idea. I'm going to try it next August when I plant tomato seeds. Thanks for sharing.
Oct 22, 2008. 10:20 PMintersectionOfSpaceAndTime says:
I live along side the Colorado river in Arizona. My tomato plants live outdoors from October and into June. Once the day-time temperature reaches 100°F the plants stop producing fruit. They die off when the temperature gets around 110°F. They're thriving right now, growing an inch a day, as the daily temperatures are only into the 90s.

you plant tomato seeds in august? Where are you???
Oct 20, 2008. 1:21 AMbluefringes says:
I'm wondering if this idea can be combined with Mr E Man's "Almost Free" DIY Hydroponics? I mean, can hydroponics be done using a cut in half plastic bottle?
Sep 13, 2008. 5:10 PMboyrock375 says:
a simple solution to the salt build up problem is that you could use distilled water. and to make up for the lack of mineral's you just add fertillizer as needed
Jan 27, 2008. 8:06 AMdanjo says:
By only watering from the bottom you might eventually have a salt and mineral buildup in your soil. (Mostly if you're using hard tapwater or maintaining the container for a long period of time). As the water moves up into the soil and evaporates it leaves behind any trace salts and minerals, they'll build up over time. Normal watering tends to flush these out the bottom. If anyone has ever used one of those double layer african violet pots they may have had similar problems. Not a reason not to do this, but just to be aware of so you can troubleshoot effectively if your plant starts suffering.
Feb 5, 2008. 9:59 AMdnsnthegrdn says:
Distilled water should help with that shouldn't it? What about rain water? Could be a good idea to give them a periodic flush to help with the problem. Smart thinking danjo!
Jun 10, 2008. 12:18 AMcgthayer says:
The bottoms can also get a green algae growth since sunlight gets in through the clear bottles. It should be pretty easy to take off the base and give it a quick hand rinse if it's looking dirty. I would actually avoid distilled water because it may be missing minerals and nutrients that the plant may need, but that depends on the particular water and plant. I haven't tried any plant food or fertilizer....hmmm... Thanks
Jun 11, 2008. 5:11 PMandrew101 says:
thats false. plants dont get minerals to survive from their water. that should come from the soil. think if a plant is wild the rain is in a way distilled water because it evaporates then condenses again. so as long as u have rich enough soil. the less minerals in the water the better. distilled is the way to go as far as this project goes
Aug 21, 2008. 12:44 PMmakaalohilohi says:
it's deuterated water you don't want to be giving your plants. it's slightly heavier, and can't be drawn through the plant's vascular system by transpiration.
Mar 28, 2008. 5:24 AMsatanclauz says:
i totally invented this when i was like 7!! well... sort-of... my invention was just a "hydro pot", the same bottle concept but with no dirt and keep the cap off and put whatever roots in the water :) your version is a fantastic take on my idea, i expect royalties soon! ;) this is a great project to do with the kids, they can even decorate their own bottles!
Jul 27, 2008. 1:52 PMresonanteye says:
I'd like to know how to make one of those for my seedling starts, wish someone would make an instructable for it
