Intro: Colander hydroponicsMake a cheap and easy hydroponic setup with household items.You need a dark bucket.A colander that will fit on the rim of the bucket.An air pump, a few feet of air hose, an air stone.

Image Notes1. Use a non- metallic colander.


3/8


Step 1:Bucket & airTake a clean dark bucket.Remove the handle bar.Why dark ? Otherwise you'll have algae grow.Does not have to be black.Why clean ?..... Leftover of soap or chemicals are not recommended.

Image Notes1. I slip the air-tube inside the hole, so it won't move.2. Watch the water level regularly. Do not let your plant dry out.

Step 2:Plant inside the colanderYou can plant almost anything in the colander.Bulbs work great.On the picture, you see an Amarilys also called HippeastrumThese are very easy to grow, i grow them on water without nutrient !If you carefully rince the roots of a young plant, and remove (almost) all soil, you can transfer it into hydroponics.A young plant will have fewer and lighter roots.I have done it many times, it works.


4/8


Step 3:Add mediumMedium is what will hold the plants, and help transfer the nutrient to the plant.You can use pebbles, sand, fired clay ,hydroton.


5/8


Step 4:Pump & airstoneBranch pump and airstone.Add water till it touches the bottom of the colander.

Image Notes1. I slip the air-tube inside the hole, so it won't move.2. Watch the water level regularly. Do not let your plant dry out.

Step 5:ResultsSee the results.I grow these on a radiator in front of a window, so they have enough light and heath.Growth is spectacular, sometimes 1 inch per day.

botronics says: Jun 11, 2010. 10:15 PM REPCan you do potatoes, onions and garlic this way?

chefmichel says: Jun 12, 2010. 7:12 AM REPI only grew Amarilys (hippeastrum) but I am certain it wil work with other plants. There is no reason it will not work. I personally switched to sub-irrigateplanters, see www.instructables.com/id/Ultimate-Vegtable-quotEarthBoxquot-For-CHEAP

pocdragon says: Jun 28, 2009. 5:28 PM REPwhats the point of the bubbleing airstone, just to aggitate the water?

botronics says: Jun 11, 2010. 10:14 PM REPThe air helps to keep bacteria down and keep the roots from "drowning".

chefmichel says:Jun 29, 2009. 12:49 AM REP

Airstones will agitate the water when air is feeded into them. Most important is to keep the air-hose low in the water. If you can keep your air-hose undewater with a heavy object, I am sure it will work. Have you ever build a hydroponic system ? Try it, it is cheap and fun. Good luck to you ! Chefmichel

chefmichel says: Aug 25, 2009. 7:50 AM REPI am not a professional gardener, but read that the bulb has all it needs. See www.gardenweb.com and other web sites. I use tap water. Just make surthe roots get enough "splash" You can also use hydroponic nutrients, it might grow even better. After the growing season, cut all the leaves flush to thebulb, and let it dry. Read more on "forcing the bulb". Good luck to you, keep us posted re the results.

DanielSedgwick says: Jun 9, 2009. 4:20 PM REPFor a cheap "airstone" i found 1/4" soaker hose for drip Irrigation works well. Found it at Lowe's

elpa says: Oct 5, 2008. 6:43 AM REPThat's cool and cheap and beautiful! Thanks for sharing, one question about the bulbs: what happens after the flowering ? Does the bulb end its life or

produce other bulbs underground ?

chefmichel says: Oct 20, 2008. 3:36 AM REPThese bulbs are very resistant. You can leave the bulbs in the colander to dry, and reused them next season. The year after however, I got onlyleaves....no flowers. I have to look this up or ask my supplier the reason why. Maybe next year I'll have flowers. By the way you can plant them in soiltoo.

Rainmakker84 says: May 12, 2009. 11:14 AM REPYou need to force the flower bulbs by giving them a cold treatment. The leaves are providing energy for the bulbs and when they bloom. They will bspectacular. Bless

littleangels says: Nov 6, 2008. 1:36 AM REPFor the nutrients, could one use worm casing "tea" with all the dirt and grit filtered out?

chefmichel says: Nov 9, 2008. 6:50 AM REPit sounds like a good idea, Try it out and please tell us all how it works out. Good luck. Chefmichel

MrTheTooth says: Jan 16, 2007. 7:21 PM REPWhat I'd like to see is a way to do this whole process with homemade/found materials. That includes the nutrient solution. There must be some way ofmaking he nutrient solution at home with compost... Just throwing out an idea, I am great at keeping Animals of all types alive (snakes, cockroachs, giantwater bugs, nake mole-rates, etc.), but I keep a healthy plant i f my life depended on it.

Saint_Awesome says: Oct 28, 2008. 2:54 PM REPDilute human urine is chock full of phosphorus and nitrogen.

DELTA_117 says: Jun 14, 2008. 11:09 PM REPIf you have some fish, I think some unfiltered fish water would provide nutrients

chefmichel says: Jun 17, 2008. 12:20 AM REPI think it is great idea. You can find a lot of info on the web re this topic.

Kevlarster says: Jun 3, 2008. 7:57 AM REPI've read that Alfalfa tea will work as a nutrient and will also LOWER THE pH, which is desirable when using 'tap' water (which is usually alkaline).

chefmichel says: Jan 17, 2007. 4:33 PM REPUnfortunately I am not a chemist, so i cannot answer you. I am planting with hydroponics for a few years and enjoy making my own setups, but i buy th

nutrients in specialised shops. I suggest you look up "composting" on Google or other search engines.

josheeg says: Aug 4, 2008. 8:36 PM REPit would seem to me to make the system better is add a nylon wick for if the pump breaks or watter level lowers. Also this could mean less bubbling duringthe day when the plants take in co2 instead of bulbing o2 at the plants.

chefmichel says: Aug 12, 2008. 8:01 AM REPAll the fun is in experimenting and improving the system. I have grown beautiful flowers even without pump, if the colander just touch water, it is OK, thplants wick whatever they need. Just make sure there is enough water. My plants never complained about CO2 bubbling, but my wife complained abouthe bubbling sounds.

jeffroward says: Dec 14, 2006. 8:43 AM REPi'm a little confused by you "air lift" water pumper thingy. this is your second instructable in which you have it pictured, and in neither of them do you have itpositioned in water or nutrient solution or anything. if it isn't in the solution, there's nothing for it to lift, right? could you, perhaps, show us how the entire thingoes together and functions when it is all hooked up correctly? or, could you tell me why i am incorrect? thanks. btw, this is an awesome, simple setup;forcing bulbs and watering orchids could both benefit from this simple technology. thanks!

Kevlarster says: Jun 3, 2008. 8:01 AM REPAmen, Jeffroward

chefmichel says: Dec 14, 2006. 4:48 PM REP

This setup is a bubbler, not a lifter. Bubbles coming out of the airstone splash the bottom of the colander, thus wetting the medium. This is a simple andeffective way to bring nutrient to the roots. The roots will grow trough the slits of the colander and reach the nutrient. Many commercial setups you canbuy in hydro shops work this way. Sorry for the confusion caused by the wrong picture. I'll post a clear drawing instead.

motoxer1254 says: Jun 21, 2007. 2:04 PM REPWhat is the teal tube for?? and what is it attached to?

chefmichel says: Jun 21, 2007. 4:08 PM REPThe tube is attached to an aquarium airpump.

backcountry says: Dec 14, 2006. 10:06 AM REPI grow orchids semi-hydro. It is cheaper and greener because it requires no pump and no electricity. Doesn't dry out between waterings like full hydro, butPhrags certainly love it. Take a cup, glass, or anything that will hold water. Punch a ring of holes an inch up from the bottom. Fill with expanded clay pellets

(aliflor) or whatever media you'd use for full hydro. And your plant of course. Then fill with (up to the holes) with a weak nutrient solution (I use "weaklyweekly"). The clay will wick the water up and keep the plant supplied.
