Hydro question

I started a hydro set-up and have some questions any help would be much appreciated. I am using 2 3'x'6' trays 8- 3 gal. pots in each, the trays are 1/4 full of hydroton and the pots are full of hydroton. I transplanted clones from a easy cloner bare root set-up. I have a top feed drip system pumping water from a full 70 gal. res underneath the tables(the res is equipped with 4 large airstones. I had the water timer set to water every hour for 15 min, during this time the tables would flood while continuing to drain back into the res, kinda like a recirculating system for 15 min every hour. My question is, is that too much water?? they were/are showing signs of over watering. and how often should I water using this top feed, flood, recirculating system???

The only way you know that you are over watering your crop is that is when the leaves are drooping too much.

try adding bleach to your solution at 1000ppm works great.

Sure why not. And if he wants to kill himself along with the plants he can add some ammonia - WTF?

PS - for safeties sake in case you don't know - mixing bleach and ammonia releases deadly fumes - please don't do it.

lots of weird post here tonight

If you are trying to do a flood and drain system you should turn on the pump and time how long it takes to fill up the tray. It is usually 15min three times a day. Check this out YouTube - How to grow green part 5.

Any answers besides the bleach thing lol

3 times a day during lights on no water at night during lights out? this sound good to everybodyelse?? remember this just bare roots in hydroton no rockwool.

Yeah, and at lights out run your CO2 with the fans off twice for 15 minutes. Watch the Green Man "how to grow green parts 1-9". It should answer all of your questions.

thanks for your help sticky

If I remember right green man uses 4" rockwool and waters three times a day with a drip in his veg area. With no rockwool personally I would just start cutting it down an hour at a time till you see the leaves start perking up ie: go to once every two hours and see what they look like. Or maybe go to straight to every 3 hours to start but just keep a close eye on them. If any of them start leaning over water quickly. You could also try setting up one pot exactly as you have the others (no plant) and use it to just to check the hydroton moisture.

I'm completely guessing here so please take it with a grain of salt, it's just what I would do. Hopefully someone will chime in that has experience with growing in only hydroton. Keep us posted, I'm very interested in the method your using.
