Relax Brah. Your tank temp is OK.
As long as the water is clean and the light is excluded you can run as high as 90 F. in the res.
Maybe higher, ah dunno.
But I've run near 90 for 3 weeks and did not change out the water at all during bloom.
I use no preventative other than what's already in my tap water and have yet to see any problems, (3rd grow).
Course, that could just be luck.


H.S. is right about the PH.
You'll want to keep hydro at 5.2 - 5.8.
Don't have to be too ridgid about it, they benefit from a little PH "drift".

I see you are using Hydrotron clay pellets.
I'd advise you to start your res water at 5.2 because the H'tron will try to raise your PH constantly, even when properly conditioned.
You can use that fact to schedule PH adjustments and sweep the range where plants use all the basics well.

Shake is also right about your form filling.
It's a pain, but it's why you have not been "being served"

Weezard Reviewed by Weezard on . Help with bubbleponics I just built a bubbleponics and has been running for 48hrs. This morning i woke up and it was filled with foam so bad that the pump was barley working. What would cause this? Also the bottom of my plants are yellow greenish now (is that from transplanting?). My temp is about 75 degrees with 65% hum. am using the same setup as stealth hydro sells but i made it myself. My lighting is 2 100 watt cfl and 2 leds. (2 leds are equal to one 400 hps so they claim). My plants were started in dirt pots Rating: 5
