Just a tip for watching BBS for new info. I use NetMind: http://mindit.netmind.com/ Enter the URL that you want it to monitor and it will email you when the page is updated. If you're like me, you want to know every time someone posts to the board, but you don't wanna check it everyday.

Have fun and keep growin'! Erik - Ohio - ehoover@netdotcom.com

Now that is something I can use. Thanks Erik.

I'm almost finished with my 11-plant garden. Thanks for all the info Ron.

In regards to aeration: I'm using a submersible pump (170GPH). I don't want to run another power cord to a air pump. Can the submersible be used somehow? Can I split the output from the pump and just let one output churn around in the nutrient tank?

Also folks, at smarthome.com (and other sites) you can get an X10 starter kit for 29.95. The IBM branded version. If you have a computer (which seems a given if you are reading this) this seems a good timer option. I had to order a 3-prong(e.g. grounded) controller for my pump, but those are also being cleared out (Magnavox branded: $4.99).

Thanks again. And, I'm TUI (typing under the influence), so feel free to edit... :)

Yes you can aerate that way. A lot of submersible pumps (Power Head) comes with an aerator tube built in.
Yes I have been using X10 stuff along time now. I have their hole house control system but have yet to set it up because I have so many things hook to my computer now, I ran out of IRQs or something like that.
I use their remote cameras to keep an eye on my property because they are so cheap.

You don't need to aerate your nutrient solution. The easiest way to do it if you really want to, is to allow the pump to continue for 30 seconds or so longer than is needed to reach the overflow. The nutrient solution falling back into the tank will aerate it.

hydro tomatoes in a 7' tall greenhouse. plants are at the roof. is there a way to lower the plants without breaking the main stem? have been keeping the plants pruned so the lower part of the plant is all stem. need more growing room.

Yes slowly  lower your string, thus lowering the plant slightly down and to one side. Only lower it about 6 inches at a time to prevent braking the plant. Start at one end of your row a do the same thing to each plant in the same way and direction.

hi there what is your source of P ?

you see, i tried using Monopotassium Phosphate as my P source and it turn out to be a failure. 3 weeks into that chemical and it seems my roots ain't growing the way it should

when i change to Peter's Hydrosol, just in 12 hours, new root hair starts to pop out.

wonder if you have answer to this mystery

thanks

pzing

I am using a :
5-11-26 Hydroponic Water Soluble Fertilizer                    - 5 ounces
Calcium Nitrate                                                                 - 4 ounces
Magnesium Sulfate                                                            - 2 ounces

I mix all three in a blender with enough water to liquefy it.
Then I mix that to my reservoir and use my  meter to adjust to the correct ppm and pH. 

Correction 

I was just informed by someone who knows that I shouldn't mix the Calcium Nitrite with the hydro mix because of conflicting chemicals. 
So I will add the Calcium Nitrite separately to my reservoir. 
I should have known it was left out of the hydro mix for a reason.

On your order form for the 11 plant garden, there isn't hand 90 deg. fitting/2 liter cap or the two 90's for the overflow. I can't find anyone in my area that sells 1" thin wall pvc. Is there any suppler on the internet?

Thanks, JJ

Try a True Value Hardware Store and ask the manager to order you some from a store in Florida where they do sell thinwall PVC. Or just order what you need from me

Is hydroponics more environmentally friendly than organic gardening? What are the benefits?

You can't get any more environmentally friendly than hydroponic growing because the nutrient water in hydro systems are retrievable and don't run off into the ground, season after season. Even organic gardening in dirt creates a problem over time.
Not even 20 miles from me here in Central Florida the state had to buy out the vegetable muck farms north of Lake Apopka. Because of decades of fertilizer runoff into the lake it virtually killed one of the largest lakes in Florida.  Birds are dieing and the alligators are even born deformed.
Their is a restoration project going on to try and save it.
Hydroponics is the future and will be the only way to grow as more dirt farms disappear.

Dear Ron, I have used your plans for the 11 plant system, thanks for providing them, although I am a bit confused on the amount of time the plants should stay in and out of the solution. I am planning on growing container tomatoes in my green house the aggregate that I will be using is leca or the puffed clay. I would also appreciate advice on the best seed starting method. Many Thanks, Jason

The roots only need to be watered every 15 minutes or so. The plants don't need to sit in the nutrient solution longer than it takes to fill the garden. The overflow is provided for people with timers that run longer than it takes to just fill the garden. If it takes 3 minutes to fill the garden to the correct height then set your timer to come on for three minutes every 15 minutes. That is if you can set your timer to do that.

hey ron, can you buy MH and HPS lights at lowe's (eagle hardware and garden) or true value hardware, if you can do you know about how much they are?

Some members say yes. I know they sell low pressure sodium outdoor lights. Not as good as HPS or MH.

I am a first time user of hydroponics, and I was wondering if it would be easier to start with using a drip system or a flood system. I have heard drip systems produce better results because the root ball stays small and the plant spends more energy on vegetative growth. Then I have heard drip systems take experience, but I have set up drip systems for our vineyard and really wasn't tough. Any answers would be great.

Thank you Grant W Missoula MT

email GW8662000@yahoo.com

Yes the drip system is easier. I am growing 100 tomato plants with the drip system now. I am even using a 10 dollar timer to drip 15 minutes on 15 minutes off.

can you turn a highbay light sideways instead of hanging it down?

Not unless it is a universal bulb which can be used ether horizontal or vertically. It will work but the life of the bulb will be greatly accelerated .

Hi Ron, I have a system where my plants are in Rockwool and are sitting in an aerated nutrient solution 24/7. This has worked fine for me in the past, but recently my plants have been getting root rot and dying. I'm wondering what the lowest temperature the water could be before the roots start dying. If you have any other suggestions as to why this is happening please let me know. Thanks, your sight has been a great resource.

I tried rockwool with my first garden I bought from HydroFarm 10 years ago and I had a problem with root rot. After that I built the 2-liter gardens that used growrocks and have been with them ever since.
I would use the drip from the top method with rockwool to prevent over watering.

I remember reading somewhere that I should thoroughly rinse perlite before introducing my plants to it. Something about dangerous airborne particles or something. Is this absolutely necessary or can I get by ok with just taking the perlite outside and dumping it into my grow chamber? If I do need to rinse, should I worry about water quality?

Re: Washing Perlite

If you're worried about breathing dust from the Perlite, just take some scissors and clip the corner off the bag and stick a hose in there using low water pressure.

Fill the bag with water and then empty it into a bucket. Wet Perlite won't release any dust. Add some more water and rinse it out a couple of time and then use a kitchen strainer to put it into another bucket.

The dust is in the bag because of handling the stuff during bagging and shipping and once it's wetted there will be no more. The water will not hurt any performance in rinsing the Perlite.

I'm trying to build the system by the book. Today I bought a box of "gro-rocks" from my local hydro store. However, it doesn't look like what most people call grow rocks. I think its pumice. I've seen pumice mentioned several times on the Q&A pages, but no comments from you or anyone else. Am I okay? Or should I return it and get the clay ones.

Thanks

Re: Pumice/Gro-Rocks

The generic name for Gro-Rocks is "expanded clay". There is a hard smooth exterior and a porous interior of the rock. This keeps it lightweight.

The rock is Ph neutral and has no bearing on the growth of the plant as it does not become soggy from absorbing nutrient during the feeding of the plant.

You could also use 1/4 inch pea gravel if you feel that the Ph is OK. I'd say "Don't worry about it." The Hydro supplier isn't going to sell you the wrong stuff. The important thing is to make sure you have a good easy to use balanced nutrient suitable for the plant(s) you're growing.

If any of you are having problems getting all of the parts for the 11 plant garden-i am offering a complete kit on e-bay. Everything from the pump to the cups. Better yet for every purchase I will donate at least a dollar to the owner of this site. Amount will depend on how well these kits do. This is all high quality stuff-no junk precut and ready to go glue included go to hell to check it out.

At least a dollar. Get real. I want at least 5 bucks a garden. It is one thing to try and make money off my garden plans but please don't expect to advertise on this site. This site is for home and farm information purposes only and not for commercial use. If anyone needs a garden they can order one from me.

I like the idea of the 2 litre bottles - very simple system. Couple of questions.

How big a plant can you grow - (mainly considering chillis and tomatoes)? 

patio tomatoes and chillis ok

What aggregate do you suggest (expanded clay beads seem a good idea). 

yes
