They seem to be getting more than sufficient air bubbles in the water. Also, the roots look amazing, brilliant white. Water stays about 68-70F same as the room. That's why I'm starting to lean towards a light issue, either too intense or too close. Thanks for the input :D
Thanks for the reply buzzardbreath. They are growing hydroponically so I don't see how it can be too much water. I know they are getting plenty of oxygen.. I think you may be on to something with the light though. My ballast is dimmable so I will try turning it down to 75%
So I have 5 strains going, they are about 4 weeks old, and they are all doing great. Except Afghan. For 3 days now her leaves are starting to curl. Details are as follows:
Dwc 5 gl bucket
1000w mh 18" above
Fox farms nutes
Ppm 700 ish
Ph 5.8-6.0
Room temp stays 68-70
Your guys' input is...
How about too small? I'm setting up a 5x5 room with a 1000w hps/mh. You think my 6000btu will cool it enough? Should I use it conjunction with an exhaust fan? Then I'm going to need a humidifier and dehumidifier right?
