Ron, I want to do a hydroponic study with my school. Could the 11 plant system work in a classroom or do we need to build a greenhouse? Do you know of anyone willing to donate a system to my school--Calvary Baptist School, New Orleans, La.

How much you need to water depends on three things: the type of plants you're growing, the size of the plants, and the type of medium you're using. The first thing to decide is if your grow medium retains or repells water. You'll want your medium to dry out somewhat between waterings, so if you are using a medium that holds a lot of water, you'll need to water less frequently.

Have you heard of Israel Corporation of Agricultural Applications (I.C.A.A). We are asking proposals from them for developing a controlled greenhouse for commercial use. No but their is a lot of hydroponic greenhouses in the mid-east. Something to do with their soil like not any.

hello, my class is learning about hydroponics. Like how they work and stuff like that.Right now we are growing lettuces the hydroponic way.the way we are doing it is we have a container with stones with our lettuces in it we the lettuces up the top and the roots hiding under the stones and another container with the water and when we put them together the roots dangle in the water and we have a straw to blow bubbles.

i have heard of a idea of "hyper ventilating" please tell me if im just stupid and tired but is it true say if you enclose a hydroponic plant in a fish tank with the proper lighting and fill the tank for say 6 hours with co2 and then 6 hours of oxygen that the plant "hyperventilates" and forces the plant to suck up a lot of nutrients and makes it grow "beefier" and faster.

What are the best books to get a complete novice/idiot into hydroponic gardening. I want to grow peppers if that makes a diff. TIA Hi, I was wondering if you had a good recipe for hydroponic nutrients, I live in an area that is far from modern civilization but I have access to just about any kind of manure you can think of, even elephant. but I'm nowhere close to any grow shops and having them shipped is out of the question.

Hi, I'm doing a science project on hydroponic farming, using the Water Culture method, i need to know how to get the best results, especially with pea plants & carrots, if anyone can give me some advice, than post it on the bulletin board, please address it to J.S. of Fl hi ! i am interested in starting a hydroponic vegetable garden as a business, what size should the garden be to be commercially viable ? would appreciate a reply.

Is it feasible to use hydroponic techniques outdoors? Here in North Carolina my soil is extremely prone to fus, and vert, wilt. ncbigdan@yahoo.com I just transplanted a Grand Nane banana plant (1 ft.tall) to my 5 gal.

how often do you feed plants in a hydroponic system.how long should the pump be on and off in a flood and drain system. Can I cultivate honeydew melon by hydroponic system.I have lot of land and growing honydew melon. So kindly advice me as above system.

I am impressed with your web-page and knowledge of hydroponics. I am just a beginner and am learning a great deal from hydroponics online. My e-mail address is weirdweviewong@yahoo.com I am wondering whether I can still purchase a pump and other hydroponic hardware thru your website??? Please advise... thanks. I am very interested in aeroponics too... Sincerely, Steve

Even though we have eliminated the soil, plants still require a place for their root systems to develop. A hydroponic media is an inert substance that can provide some support for the root system that has no nutrient value. Almost any inert substance can be used. A few examples include sand, gravel, vermiculite, perlite, LECA (lightweight expanded clay aggregate) and rockwool.

Hydroponics is simply gardening without soil. Soilless growing medias such as perlite/peat-lite or perlite/vermiculite or other combined mixes, have little of the nutrients that the plant would normally leach from the soil. In this respect, nutrient for the plant has to be added in water-soluble form. Hydroponic fertilizer is added to the water containing the minerals that the plant needs to sustain growth.

Winter hut users will find large pots at the huts for melting snow. We advise that parties clean and refill snowmelt pots upon arrival at the hut, and snowmelt water should be treated or filtered before drinking. In the summer, water backpacks are provided for collecting water from springs and streams. All water should be treated or filtered before drinking. Distances to water sources vary from hut to hut (see below).

When first planted, water daily. It's good to fertilize at this time. Once established, only water during dry spells.

I have been surfing the net for about 5 years and this is the first site I have ever seen that was this informational without having to pay for something. If I ran a web site that allowed me to put up your banner I would. I am Building my own Hydroponic system just because I found this site. 20 minutes ago I had no Idea I would be gardening this summer but now I am. Plus if i build one good enough, my friends said they would by it off me for their controversial growing plants.

Do you have any information on expected crop yields for hydroponic production of veggies? Jaco, Bloemfontein, South Africa Dear fellow hydroponic fans We have a hydroponic barley shed which has been operational for 12months. No problems till now, suddenly we have some sort of snowy white growth attacking the sprouted seeds. Any ideas what it is? How to treat it? We are at present shutting down for a week to completely clean out the nutrient tank and dripper pipes(system).
