Does anyone know anything about a volmatic valve system? It is widely used by the Danish people for their ebb and flow hydroponic systems. I am curious as to how it works. Does it have the same function as the American drain/fill and overflow fittings? If so, what are the advantages of using a volmatic valve system? Whatever info you share with us is greatly appreciated. Thanks!! We are a group of engineering students and we have been asked to submit a proposal for an urban gardening center.

I have started a hydroponic tomato garden. The plants have been in it about 18 days and have really been looking good. I have noticed in the past few days that the better boy's leaves have curled up. The others are doing well though. Also, there is a brownish looking residue in the tubes and some of the roots have this brownish look to them now. The roots used to look white when they first started to grow. See similar questions...

Several flight experiments have been performed on plants, particularly on wheat. Part of the grass family, wheat is known as a cereal crop and typically used in making bread. In a microgravity environment, germinating seeds tend to grow normally with the shoots growing towards the light (positive phototropism). The roots do not exhibit phototropism, and they tend to grow whichever way they please. They will, nonetheless, usually stay within the moist medium in which the plant is growing.

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). See similar questions...

I am building a hydroponic garden for a science project, and i came up with a problem. I built a Ebb and Flow garden with pvc pipe, and i cut a long slot instead of separate holes. Now i am wondering what would be the best way to insert my groing medium, and how to do it. Thank you. I am building a hydroponic garden for a science project, and i came up with a problem.

yea i built the 11 plant hydroponic system and im going to get a pump right and ive seen pics of a tube coming out of a container does that connect to the 1/2 inch hose connecter does that bring water up back to flow or is that to give to oxygen to the roots ,sorry but im new to this Ron, Trialbozz here from Victoria BC. I've been reading your discussion board and must say it has answered many questions I have had. I noticed you have shied away from questions regarding aquariums. See similar questions...

Hey Ron i was wondering if you can make your own Hydroponic Lights and in the 11 plant System do you need to put pea gravel in the cups or just the Plant by itself P.S You have really inspired me to a new Hobby Yes if you buy a ballast, a socket and a bulb. But then you have to wirer it all together. Home Depot has a 175 Watt HPS yard light for $50.00. See similar questions...

Cam anyone recomend a type of tomato for hydroponic growing? Also, does anyone know what type of pepper is used in a chili rejeno? Thanks Mike I'm looking for a company to assist our family farms in a complete hydroponics conversion. Not just an equipment supplier, but a company that can plan, build, install, train, etc. The whole nine yards. There is a hydroponic company in Hawaii that will be partners with you and give you all the money and help you need. See similar questions...

Hydroponic systems basically spoon-feed plants their perfect food; they are highly efficient systems. In soil, plants spend a great deal of time and energy growing a large root system to find food and water. Additionally, nutrients in soil must be broken down first before they can be used, if they're even present. With hydroponics, because food and water are delivered directly to the roots, the plant can spend its energy on producing more vegetation, larger fruit, flowers and vegetables.

Almost anything, except tall growing crops like corn and certain root crops may not be efficient to grow. The best crops are leaf lettuce, herbs, spinach, tomatoes, and my personal favorite, strawberries. Many types of flowers and green plants, such as ferns, flourish in the Vertical Garden.

Yes, however you may need lights for best success. All plants need light, some more than others. Some types of lettuce and herbs grow pretty good in a southern window. Lighting for indoor systems are available. See similar questions...

Henna plants are available from garden suppliers on the internet, but they do not do well in temperate climates. They are susceptible to many garden pests, and are fussy plants. Henna grows well only in a climate where the nights are always warm, it never ever freezes, and there are at least 3 months of weather over 100F every summer. Rajasthan, Israel, Egypt, and places with climates like them, are excellent places to grow henna. See similar questions...

In general, it can take 3-5 years and even up to 10 or longer for carcinoid tumors to grow. These are generally very slow-growing tumors. Serotonin is a chemical proFcoduct produced by some carcinoids in various amounts. It does not regulate the tumors. When in large amounts, it causes symptoms but in any amount, it is a useful marker for the presence of each tumor. 5HTP is the chemical precursor (for the substance) from which serotonin is made and is also a useful marker sometimes.

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.

We are in a Agriculture class in Decatur, Illinois and we have a hydroponic test kit and we have just set up a hydroponic area where we are growing lettuce. We are trying to find out what is the exceptable ranges for growing lettuce. The ranges such as Nitrate Nitrogen range, Phosphorus range, Potassium range, Ammonia Nitrogen range, Sulfate range, Iron range, and Calcium and Magnesium range. This would help us a great deal if we would know these things. See similar questions...
