i have new sprouts, and the stems are long, when do i start to pinch the tops
After the third set of true leaves.
We have been using Reverse Osmosis water for our plants and fish and have experienced trouble due to the inherent acidity of the RO water (pH 5.8). A company recommends using mined silica clay. What is it and where do I get some? I was told: "There is also another product on the market now that is supposed to work wonders with RO water. It is actually a mined silica clay that contains 72 micro-nutrients". Any comments or suggestions will be appreciated. Thanks, R. Mara rmara@blazenet.net
A pH of 5.8 is to low for fish but is perfect for plants. pH is the problem when trying to do both.
For the person looking for silica clay. I found what your looking for quite by accident. Go to: http://www.plantitearth.com/organics.html Its called "pyroclay"
Hello Ron (or whomever can answerer my query) I just started out on my hydroponic quest and I was trying to find some cheep growing solution. I remember finding a place on the web that had some in dry form for only $5.00 or sow. But please give me any information you might have. I'm just a beginner.
The cheapest I have ever used is Nutri-sol but I can't find it anymore. So now I mix my own.
Hello, my name is Ian. I have to do a science fair project at school, and I was thinking of doing something involving hydroponics (I'm not quite sure what to do, but I'd like to use hydroponics). If anybody could help me out with this (where to get hydroponic stuff, info. on hydroponics, etc.) it'd be greatly appreciated. If you could help me, my email is Malchori@aol.com Thanks! Ian
Been busy building a list of on-line suppliers for us hobbyist. Lights, medium, nutrients & pumps. For lights go to www.hydroponics.net. The grow max jr mh is $154, the hps-$189. For water pumps go to graystonecreations.com. Cheapest anywhere. Nutrient is hard to figure out cause mixing ratios are different but if your looking for cheap, quikgrow.com has a 3 part solution for $6.00 per liter. Medium, depending on how much you need is $30 for 50ltr at futuregarden.com or hydroponics.net has the best price for a smaller quantity, 3.5 gallons for $10. I got all my supplies, except nutrient, from these people and am happy with all of it.
The moisture probe will be used as a feedback to a controller to automate the hydroponic process. I plan on using the bag technique to grow tomatoes. I plan on using peat moss and perlite as the medium. My goal is to have the prob calibrated to keep the correct moisture level in the bag at all times.
I live in the Atlanta area and I see a niche market for tomatoes in the winter months. Caterers and fine restaurants are begging for good FRESH vegetables. My goal is to build a business growing hydroponic vegs. Any advice is welcomed. Joe
Just curious. I have built a nine foot tall 14 x 20 ft greenhouse. I am getting ready to put on the plastic, and was wondering if I put black plastic on the lower 4 ft if that would
help with heating it in the winter, or if it would cut off too much light. Does anybody out there have any idea?

As for temperature control I don't think it would make a measurable difference.
what is hydroponics
growing plants without dirt
I love the sight, so in appreciation, and to keep this sight the last word on the subject, here's a bit of trivia.
The only song (as far as I know) ever to mention Hydroponics Is the Title song of Donald Fagan's (Steely Dan) Kamakiriad. The Song (whole album) is about a futuristic car and the lyric goes
It's not a freeway bullet or a bug with monster wheels It's a total biosphere The farm in the back is hydroponic Good fresh things every day of the year.
I take comfort in the fact that somebody in pop culture not only knows what it is, but that he knows that it's not just for growing the #1 cash crop.
Where in the USA can I find hydroponic tomatoes and lettuce seeds? And the prices to those seeds? Cody Johnson Tarkio, Missouri P.S. If Any one wants to e-mail me about this matter my e-mail address is johnson_cody90@hotmail.com
I am going to plant a garden and I live in North central Florida and would like to know the best vegetables to grow for the fall starting in the next few days
Cauliflower, spinach, cabbage, cucumber, eggplant, lettuce, and peas.
I have been asked to give a report on hydroponic fertilizers and I need to know percentage wise how much nitrogen, Phosphorous, and Potassium should be in the fertilizer to best help plants grow. Val in MT
What size pump should I use for a 2 plant garden. My soda bottles are overflowing but my overflow pipe vent hole is not shooting out any water.
try clamping the hose to cut down on the gph.
ron, what kind of plastic are 2-liter bottle caps made of, and what will bond them to PVC fittings? how do you glue your caps and fittings together? (do they need to be sanded or ?) i've tried regular pvc cement and a clear 2-part epoxy but they keep coming apart..
The caps fits so tight just a little pvc glue holds mine fine. They are made from different kind of plastic that glue has a hard time sticking to.
If I have 400w mh for vegetation, would 140w hps be enough added to the 400w mh for the flowering stage
Yes
I'm a High School student, and I'm doing a science fair project on growing grass in hydroponics,and seeing which type of fertilizer works best. If yall could give me any info. about what types I should use and which types work best, I would appreciate it a lot! Thanks for yalls time! P.A.
Hi from Victoria,Beautiful British Columbia,Canada. Whilst on a little trip to the USA I purchased a good light meter for growing my veggies and it is calculated in "foot candles" and "lux", however I have spent hours and hours trying to find out what optinum readings I should get for Lettuce,Tomatoes and Cucumbers, taken at the plant ! Please can you help me or tell who can. Thank you. Norman Howard Email: normanhoward@home.com
HI Ron, where the heck can I find 1" SDR-26 PVC? I've called just about every plumbing supplier in the Baltimore area as well as some irrigation wholesalers. So far I'm lost, I guess I'll just have to get some from Pipe Dreams. Any other suggestions?
I guess you will. I'll send you all you need already cut 1 inch long for a few bucks.
Hi Ron, I just noticed that you have the PVC called SLD.26 in the beginning of your 11 plant Setup page, and at the end of the slide show you have it as SDR.26 PVC. Which is the right one, and again, where can I get it if not from Pipe Dreams? Thanks.
It's SLD. 26 (schedule 26)
the numbers on the pipe probably don't make much difference, since they vary from manufacturer to manufacturer.... what you want is thin-wall 1" PVC. best thing to do is take a cap with you to the local PVC store and see what pipe it fits into. up here in washington they call it "sprinkler pipe" since people use it for underground lawn sprinklers. i just happen to have a stick of it here and here are the numbers on it:
1" CL 200 PSI SCS-430-DD PVC 1120 @ 73' F ASTM D2241 SDR 21 NSF-61 * &G27AYD29B MADE IN USA
again, i found it easier to take a cap with me and buy what it fit into...
yea what he said
back to dirt it was nice at first then low water fert. burn next time pump burn out whats next back to dirt will still read your great site iv done tests & dirt seems to grow faster hydro no way you just have to judge for your self
All you have to do is watch as my tomato plants mature
then you will have good idea how fast one can grow with hydroponics . Read the
dates on the pictures as I post them everyday.
Pictures don't lie.
You can also watch them all die if we get an early freeze here in Florida before
I get my greenhouse enclosed.
Ron you should try growing in dirt i know its a dirty word your pop bottle set up is the best
dirt is to dirty
Does anyone have the pdf file edition 2 of How-to-Hydroponics? This is one that used to be able to be downloaded, but required the Soft-lock key that you had to purchase before you were able to open the pdf file. I've managed to screw up my drive, and don't have a copy, and you can't download that version any more. I doubt that it has enough info to be worth another $20. And, I've already purchased the key to edition 2. Thanks for your help. Jim Bradley -- Maryville, MO USA (jbradley@msc.net)
Please disregard my question regarding a copy of edition 2 of "How-to Hydroponics" that I'd posted earlier. I found a copy on an archive CD that I'd burned. Jim Bradley
The ph in my reservoir (25 gal) is always acid. I'm using ph up like crazy. Changing the solution didn't help. After a few days it was acid again. I started using crushed coral. It's only been 1 day and the ph seems to be stabilized. The ppm is ok for now. What terrible things might happen?
If your pH is to high or to low your plants get lock out and can't utilize the nutrients in your solution. Thus your plants do poorly.
Hey folks, came across a great link for a TDS tester. It is a cheap one, and I don't know the quality, but it is like half the price as any others I have seen. Ron, or anybody else, let me know if this is a great deal. I really appreciate this site.....I now have built three hydroponic systems, and a greenhouse to put them in. It is a great hobby.

Hi, I have read of farmers in Canada growing plants in saw dust, can anyone provide any information? Thankx
I would like to know if anyone has tried growing Okra using hydroponics and what the average yield might be. You can email me at wilkinson@intellex.com
I got four okra plants just starting. I will let you know how they do.
hello ron, this is Bob from Newport, see you at bike week March-1st.Great page.
I didn't even make it to Bike-toberfest this year. Have to replace the motor that I blew up last year in my trike before March. I don't have no fun.
In a eight sq meter room with co2 what is causing the yellowing of leaves? when ph is reading about 7 and cf meter is reading about 22?
Lower the pH to
6 or lower 5.5.
22 might be high depending on how your
flow meter reads. You can give plants to
much co2.
hello ron,
i notice that out of the 3 types of plants i have in my hydro system (namely, lettuce, rocket salad and basil ... all sharing one tank),
the lettuce has yellowish roots.
this is my first time to encounter this. i have been doing hydro for months now. the only difference i could remember is that for more than 2 weeks now, i do not put any Chlorine in my solution. before, i make sure there are no less than 10ppm of Cl in my tank.
oh, if you are thinking that i do not change my water, well .... i do change my water. actually, my water evaporates so fast that i have to refill it every 3 to 4 days.
regards,
pzing

Not sure but I wouldn't worry unless the roots turn brown and die.
I am hoping that Bowie will have a Fresh Fields store one day soon. I realize there is a store in Annapolis, Md. I am hoping for something closer to my home.
Any plans to do this?
has anyone ever grown using co2 from a source of baking soda and vinegar is there any other methods to create co2 for a small sealed grow area. thank you
For co2 enrichment methods go to

first off would like to compliment on the wonderful site. my question is i would like to start in hydroponics and i am planning on building the system out of two 5 gal. buckets can i use aquarium gravel as my medium or should i use clay, i want to grow bananas so any help with that would be helpful thanks
The more porous the medium the better.
I'm doing a science fair project on hydroponics and it is very hard to find information on this topic. It would be very helpful if you could help me find valuable information on this topic. Thank You.
Hi my name is Matt! I am doing a project for PJAS (Pennsylvania Junior Academy of Science) and I want to do a topic dealing with hydroponics. And I was wondering if anybody had any ideas. If you do please post them on. THANKS!!
Information about hydroponics is all over the web. You can start by looking through this site. If that ain't enough, try the below sites for info & do it yourself units. There are a bunch more, you just have to look!!!!!

What is the skinny on tissue culture cloning? I only read a two page article on it but it seems highly superior to stem cloning. Where can I read more on the subject?
Disney World is
into it heavily. I took a tour of their
lab and filmed video. I will try to find
it and post some pictures.
Somebody sells a small tissue culture
kit but I can't remember who.
I want to try it.
Hey Ron! I am wondering what plant will grow good in this weather using hydroponics.
I am growing tomatoes, peppers, and herbs of all kinds. It is getting kind of cool at night (45 degrees) now. My tomatoes are just showing and if we have an early frost they will be history. I will try to cover them if that happens.
