    The root health challenge - Not for the inexperienced

    What media is in your net pots? Is it all in the same system? Maybe there is a spot that isn't getting cleaned, dirty airstone etc. Have you tried flooming instead of airstones?

    Anyone using Can Max Fans? Are they any good?

    I have the 10" and they are great. just as loud as any other fan that moves the same amount of air. You can add a foot or two of ducting if you want to quiet them down a bit. I am pretty sure you need a VARIAC style controller to adjust the fan speed. They are 60-100 $ I think but they will...

    Grow Room A/C

    Thanks CJ! I did the math at 4btu per a watt and thought I was in the clear. 9400w x 4BTU = 37600 btus. It looks like you did the math at 5btu per watt. All the bulbs are bare and unvented. I am very limited on amperage or I would get two 3ton minsplits. I have a chiller thats not being...
