How to kill mold and mildew and root rot organically.
Fresh air, fresh air, fresh air.
My seedlings germinated three weeks ago, and I still have not root growth other than the tap root. I also have clones in the same tray and they also have no root growth. My PH is 6.5 and water temp. is 78 degrees. What is my problem? This is my first attempt at hydro. I've been doing dirt for years.
on a hydro pipe system how do you regulate the water with out over flowing the cups? sorry am new at this
With an overflow pipe.
How does one grow bog plants or emergent nymphaes ( lotuses, iris) using hydroponic systems ? Radha Krishna email@example.com
how am i sposed to to set the system up?
what kind of fertilizers should i use?could i perlite and vermiculite?
hello, so i understand the need for co2. my room is 5'w x8'l x 8' h will a kerosene lamp provide enough co2 ???
hi I have a root problem, some of the roots are white and some are turning brown what's wrong? please help
what are good plants to grow as a first timer. It also has to grow a little faster.
Herbs and spices are a good start.
for this small 6 plant system what is a good pump
how long to let pump run per each cycle
Long enough to wet the roots every 15 or 20 minutes.
I am doing some market research in the area of calcium nitrate. Do you happen to know what the total volume of calicum nitrate used in the fertilizer market is? What is market pricing for the raw material? Would more be used if the price was cheaper? Thank you so much for your expertise.
I don't think it could get any cheaper.
I would like to set up greenhouses for cucumbers, peppers and squash. I can't seem to locate the links that explain how to build a commercial setup. I saw one a few weeks ago, but can't find it now that I am looking for it. Any help would be appreciated. Ron, I believe, has tried a few times to send info but my computer will not open the files.
Want to try again:

In these hydro systems using the fill and drain method...how many times should it fill and drain in a 24 hr period and how long should it be full and empty?
Long enough to wet the roots every 15 or 20 minutes during the light period. You don't need to water during the dark period even though some growers do.

Hello my name is John W. .I'm in the 6th grade. I'm using hydroponics for my Science Fair at school. My teacher wants us to have an expert comment us on our hypothesis. My hypothesis is: I believe the plants in potting soil will grow bigger, stronger and faster because of minerals in it. Could you please comment on my hypothesis? Thank you John White at firstname.lastname@example.org.
ATTN: John White
Are you saying that growing in potting soil is better than growing hydroponically????
No he was saying that he believed his hypothesis was right that plants do grow faster in dirt than in hydro and was inviting a so called expert to disprove his hypothesis. I can see that you aren't that expert.
ron: i am planning to make your hydroponics kit which you show in the 8 lesson hydroponics tutorial, and i probably plan to place it inside in a room with little to no ambient light. If i grow beans, what type of light/lights would be the best setup in terms of cost effectiveness vs. how well they provide the plants with light? i would welcome any input that anyone has on this topic.
P.S. i am building this for a science project
This is John White again. My science fair hypothesis says that plants in potting soil will grow better than in a hydroponic garden. I said this because I don't know about hydroponics yet and wanted to learn if it was just as good as growing in soil. After reading my research I learned that hydroponics gives plants the same nutrients as potting soil but in a different way. I was hoping you could comment on my hypothesis for my project by saying whether you think plants do better in hydroponics or just the same as in soil. Thank you for your time. I think hydroponics is cool! John White
Attention: John White
There is NO comparison between growing in hydroponics and potting soil. Hydroponics wins hands down. Keep in mind that in hydroponic growing, the plants are being force fed nutrients whereas in soil, the plants put out more roots seeking nutrients in a form it can use.
I usually buy 6 packs of seedlings at my local Home Depot. Those that I don't put in a hydroponic setup, go into the ground. The difference in the growth rate and production of fruit is almost unbelievable using a hydro system. An added benefit is that I hav'nt had any bug problems in the hydro garden and am able to grow without using any poison sprays.
Looking for some info on a hydroponic project for lettuce, living in the Caribbean and looking into the posibility of cultivating lettuce by hydroponic.

I have decided to move to the middle of Cape Youk on a block of land I have aquired and would like to see a photo or two of a small setup that may sustain several families, I know what you can buy but some times you need a visual.
Any photo`s can be sent to
I have only just found this sight and look forward to hearing from anyone.
Is anyone familiar with homebuilt hydor stadiums.
What is some statistical information about hydroponics?
hi. sulfuric acic will lower PH sodium hydroxide or sodium chloride will raise PH eg;lettuce CF 8/12 PH 6-7 pepper CF 18-22 PH 6-6.5 tomatoes CF 20/50 PH 6-6.5 question; how do you get the CF up or down and the PH remains the same eg;pepper and tomatoes

Umm... I'm thinking about growing plants hydroponically as a science project for school and I've been researching it for awhile but i'm still not sure what plant would be best/easiest to grow. I only have until may-ish to grow them, and I'd like to do it as simply as possible so any suggestions would be really nice... thank you!!
I have to do a chemistry project for school using hydroponics. The thing is I don't have any experience in hydroponics. I already did some research and i have purchased the following equipment: 400 watt MH lamp, 5 and 10 gallon Rubbermaid containers, air pump, water pump. I don't know what kind of nutrients to use or growing medium. I also need ideas on something easy to grow that would react well to different types of nutrients. Ideas on home-made nutrients are the main point that iam aiming for. And you have to keep in mind that this is for a school chemistry project.

Hello, I am new to hydroponics and am going to build the basic 11 plant garden to try to grow tomatoes. There are two questions I have at the top of my head.

I'm a small-scale veggie grower, using hydroponics for some of my crops. I'm thinking about starting up a hydroponics ezine (online magazine), to share information I've found about cost-effective building methods, growing strategies, online resources, etc. I'm trying to determine how much demand there would be for such an online magazne, before I go through all the work of creating it. Would any of you be interested in subscribing to such an ezine, for about $10 a year?

I've been growing for about 2 years now and due to unfortunate 'incidences' I have never been able to finish the flowering stage of my indoor soil grown herb. I'm using a 2-3 Gallon pot as the final stage and the plant is now almost 1.5 meters tall, and is now flowering. Is this a safe pot size to stick with? I am now seeing the sativa hairs sticking out everywhere, and I'm not using any fertalizers or nutrients. Is there a natural nutrient source (that I wont have to buy) that I can use to increase the speed and size of the buds development? Thank you for your help, and great web page bud!

Could I use an ordinary sponge used in furnitures, to replace rockwool or perlite? or ordinary pebbles used in aquariums? I'm having trouble with local distributors cuz they don't have any.
Many people seem to have no idea as the the chemicals involved in hydroponics, so I'll take a shot at these. Fist off, Calcium chloride is NOT a substitute for Calcium nitrate. Some of the chemicals that are absulutely necessary include: Calcium nitrate, Potassium phosphate, Magnesium sulfate, small amounts of chelated metals (Fe,Cu,Mn,Zn EDTA) and trace amounts of boric acid, molybdic acid, and cobalt sulfate. Other chemicals are necessary for pH control, acids to lower pH -phosphoric or nitric acid, and Potassium hydroxide to raise pH if necessary, or sanitation chemicals like hydrogen peroxide. For those people who are not chemists, it is best to use a nutrient specific for hydroponics - Look for high percentages of nitrate verses ammonia/urea. Stay away from soil nutrients like miracle grow as they do not use calcium nitrate, but rather urea.
How well do African violets grow in water?
I am building an 11 cup plant system. I can see the fluid level, however how long should the water be at this level?
Just enough for your roots to get a good watering every 20 minutes or so. But that takes a cycle timer. That's what the overflow is for so you can use the inexpensive timers.
