Great Site. I'm growing some tomatoes and would like to know what my TDS readings should be. I have a Hanna Meter but am not sure where I should be at what stage of growth. Is there a chart or something to follow. My plants are doing Ok ,but I would like to find out more info for different plants. Im currently at 490PPM and want to know when to increase,etc. Thanks Bob
You need to step it up to 700 PPM or so.
Hi, I bought the 11 plant garden last year and have been happy with the results. I can't find any online info on growing st john's wort hydroponically. I was wondering if anyone could share anything. Email address is warmth@cheerful.com. Thanks in advance.

To run a 400 watt light 12/12 would require 144 KW hours per 30 day period. If electricity costs 10 cents per KW hour in your area (that is near average in the US), it would cost $14.40 per 30 days.
Rockwool will work in an "eleven plant" type system
The 11 plant setup doesn't need an air pump, it needs a submersible pump that will circulate the nutrient solution. In addition, you could use an air pump with an airstone (like the ones used in fish tanks) in the reservoir to increase oxygen content in the nutrient solution, but it's not necessary for the beginner.
Swapping 100 watt hps + florescents with 400 watt mh will speed the flowering process, just make sure that it's about 16 inches from the tops of the plants. If the plants start to turn brown and dry out, the light is too close.

Yea What he said.
Is the system on the Dayton Flea market page ( the one with the multi levels on it) Is that an Eb and flow design? I've been trying to figure out how the nutrient level is maintained in the grow cups. Its probably really easy, I can't figure it out though
It's a drip from the top system because of the different levels.
Ron, is it necessary to have a pump circulate your water solution. Would changing it every so often adequate? Also if the tomatoes are already sprouted, can you simply submerge the roots in a nutrient solution rather than using rockwool?
yes, no and no
Hello Ron! Thank you for the opportunity of this site.
I'm looking for a job with hydroponics in Florida. I have good experience with lettuce and other folliages. My home phone is (813) 661.4841 or e-mail: fsantanaus@yahoo.com
If this could be posted, I'd be most grateful. Yours, Fernando Santana.
Fernando this might be obvious but sometimes thats what we don't see. Contact County Ext offices they can give a list maybe of what is in their area. Also some cities have offices with lists of business they give out. From what I gather there is more interest in hydro in the South Central part of the state like around Orlando. UF also may have lists in their AG dept. Good luck S.T.
Hi would anyone want to stop by this MSN community?
http://communities.msn.com/Hydroponics
Post some pictures share some knowledge!
I posted the first hydroponic picture on MSN when it first started years ago. I wonder if that black and white picture is still there.
When did Ron become an agent for Man-Power?
I got your man-power right here.
Hey Ron, very amazing pictures. Would you happen to have any recent pics of your banana tree so we could see how big it is now?
It froze this winter but now I got eight coming up in the same container.
Ron, I came across a large bag (50 lbs.) of HYDROFORM 30-0-0 CHIP CONTROLLED RELEASE NITRO. CAN THIS BE USED IN MY HYDRO GARDEN OF BUSH
Maybe. That will take care of the N but you still need some P (phosphorus) and some K (potassium). And don't forget the micro nutrients.
I have a pest problem, Is there any homemade concoctions that work better then store bought ones? Any info would be appreciated! Thanks, Desiree
I am just getting started in the hydroponics world and wanted ordered a 3-way light, soil, water PH tester. The company I ordered it from said they were out of stock and would not get any more. I have looked elsewhere online and have not yet found another. Do you know where I can find one or are they reliable? What kind of tester should I get? I did not want to spend a lot of money. Any info would be appreciated.
Careful those dirt pH and soil testers are different than hydro testers. It might be a good thing they were out.
Hey ron, Your site inspired me to build my own Hydroponic machine 2 years ago. I was going nowhere in life back then, 2 years later I have made aeroponic machines for people who needed to purchase them in a discreet manner. Although I only made one of your 11 planters and then went on into aeroponics. You were my inspiration and I would like to thank you for the site.
Remember me in your will.
hi, I´ve built the 11 plant system and I have some tomato plants growing in grorocks & Flora series. I put the tomatoes in the system less than 2 month ago. The tomatoes don´t grow very much (are 7 or 8 inches high) but they started flowering already. Should I leave these flowers or prune. This is my first attempt with hydroponics. I'm in Mexico City, lots of light and warm weather, not very hot yet. Thanks a lot, Victoria victoria@quetzal.innsz.mx
Flowers turn into tomatoes so if you prune the flowers then you just lost your fruit.
Hey Ron, I live in Tampa, FL and get my supplies from worms way. Are there any other hydro stores around here? Just wondering...
Not that I know about.
Dear sir/lady Thank you for your attention to training hydroponic systems. My name is Majid Kazemnezhad. a 28 years old man. I am not graduated of agriculture university. But I love nature specially fast hydroponic systems , because it dosen't not need big places. Please send to me : 1- How can I study lessens about it in my own home. 2- Address of books, magazines, cd's, training films and etc. 3- Do you know any producer or your member in Iran or Turkey. How about the other countries... 4- As I am interested in establishing an institute in order to produce crops and ... which services you give to your members like me. E_mail: hydro_majid2002@yahoo.com Thank you.
Thanks, Phillip
For that short of time sure.
Hello guys What is the effect of nutrient concentration on strawberry yield?
thanks
Thanks Ron, I know flowers turn into fruit but I thought I shouldn't let the plants fruit yet because they are so small. Victoria
Sooner the better. I have golf ball size tomatoes on my 12 inch super bush plants.
Ron I'm the guy with the 50lbs of n 38-0-0 i have a 11 plant garden. I understand about the other nutrients , what strength should I add the N though thanks
5 oz per 50 gallons of water.
hi, I have to do a science fair project. So I chose hydroponics because it looked interesting. I am growing yellow peppers. My set up is my plants are in a small tin with different watering solutions because I want to see which one works best. I have been trying to grow my plants for about 5 days but they just aren't germinating if you could please give me some advice please write me back at LewisT@grenvillecc.ca
Hello -- I just want to mention that Art Smith from Alabama Hydroponics (http://www.alabamahydroponics.com) is kind enough to host Tomato Challenge 2002. The basic objective is to grow tomatoes hydroponically and you can use any system to achieve that objective. In case you are curious about the rules, please visit his website and learn about them. As a matter of fact, that site should be viewed as an excellent place to get feedback from other tomato growers. I had a lot of fun with Tomato Challenge 2001 last year and met some really cool people on the internet. hydroponically. Hope to see you all at the contest. Happy Growing, Wayne
any interest in mexican bat guano?? cheap!
My plants are in the last stage before drying, but they are now turning yellow on the tips of the leaves. Is this because of too much watering or the pesty nats eating on the plants?
Please tell me the method for getting rid of black,tiny nats without hurting my plants or the taste. Also, the tips of my leaves are turnig yellow. Why?
This is going to be the first year I will not have a garden of tomatoes and peppers in my yard since I retired 14 years ago. Arthritis has claimed most of my body and my ability to garden has been cut by 90%. I would like to try hydroponics so I can still have a crop. I need something simple and with low maintance. Please can anyone help me.
Thanks
Steven
Thanks again Ron. I´ve read a lot about growing, but I found nothing about the end of the life of a plant. When to discard a tomato plant? Does it fruit for more than a season? more than a year? Victoria.
Tomatoes
are indeterminate plants which under
the right conditions (like in a
greenhouse) they will produce fruit continuously.
But here in Florida I get two
complete harvests in the spring and
fall under my shade cloth
greenhouse.
Ron, is that some new Long-Stem Hybrid Romaine lettuce in your "what`s new" page? Sure looks Yummy!!
No it just grew that way before I harvested it. It was good. I ate salad for three weeks.
Thanx for the fast service on the order!!
Your welcome. Orders come first.
I am doing a project at school that requires me to use Miracle-Grow for the nutrient solution. We are growing peppermint plants and I need to know how to mix the solution so the plants have the required nutrients.
hey ron, beginner using 11 plant system and wanting to know the best pump to use? whats best method to sit the plants into the 2 liter bottles? what is the best mixture of "hydro juice"? how much yield should I expect from a plant and how often?
About a 100 GPH submersible pump.
hey ron, how many 400 watt lights should I use for the 11 plant system? whats the best mixture to use for the "hydro juice"? how often changed? ph level? would appreciate any help! thanks
Sincerely, Jason
You could put two 11 plant gardens under a 400 watt light. The best mixture is Formula One A & B
Do I have to use aerator or pump to supply oxygen if greenhouse is outdoor?
It helps indoors or out.
I am trying to grow a a 2-4 plant-hydroponic garden. I ordered the following unit, for $70,
from Harvest Moon Hydroponics.
here is the description The recently redesigned HomeGarden System is an outstanding unit for the beginning hydroponic gardener. The submerging the grow rocks. A full-length airstone and external air pump continuously supply oxygen to the reservoir. Capillary matting surrounds the grow rocks and keeps medium moist and helps deliver nutrient-rich water to the starter cubes on top of the system.
total cost is a factor (limited budget), my question is can someone rank in order from most important to get exactly what is listed on here and what items you can cut costs by purchasing something like what you need.
Example could be Lights or is what I already purchased really not needed ?
PLEASE HELP ME! thanks
hey ron,just wanted to let you know your hydro plant food is great.i am getting better results than when i was using ionics two part liquid.much faster growth & easy to use not to mention price.george in crescent city florida
Thanks. I am getting good results also. Some members have complained about it not dissolving completely but if it doesn't cause any problems who cares.

After spending a number of days reading the comments, questions and answers (YES I mean DAYS!) I did not find a correction to a couple of statements made by you in the early pages regarding the use of a multi-meter or ohmeter for measuring EC. You said that such a meter could not me used because an EC meter needed a power source to cause a current to flow in the liquid, and these meters did not have one.
An ohmmeter actually measures the conduction of current through the item being measured and uses ohms law to convert the current reading into resistance reading. To do this is does have an internal power source.
To change the resistance reading to conductance you have to take the reciprocal (dive the reading into 1) Since the EC is per centimeter the probe must be made correctly to take this into account.
So if you already have a good multimeter just make up a probe and save some money.
John McCaslin
I have a hard time reading a multimeter. I'll stick with a EC meter.
So tell us, how do we make this probe???

Why is there a lettuce shortage?
My supermarket said bad weather in California.
Ron, do you need to add calcium nitrate to the Nutrient mix sold on this site? I will be growing mostly fruiting crops (tomatoes, peppers) and some lettuce.
Thanks.
No you don't.
