Thanks for your detailed response!

Temps have been barly hitting 60 during the day so, I have turned the thermostat up a bit on the intake fan and have turned the fan speeds down as well. Im slowly bringin the heat up. Its funny because normally heat has been the main issue using these hps's. One problem is at night the fans are just off so there is no heat persay.

One problem I see is the fact that the system does not recirculate. They are just connected at the bottoms. Also the controller bucket is in another room were the temp gets in the low 50s if not lower. I put some blankets around it and under it.

Im goin to set all the buckets up on something, thanks for the tip. I am thinkin though it might need a warmer of some sort of seedling heating mat under the controller bucket to raise those res temps. I stuck my hand down in it and it was almost too cold to touch.

I believe at the start most of the yellowing was from not using the calmag. I wish they would have foliar feed them but now I realize its too late..

I wonder if this yellowing is going to effect the finished quality? None of the hairs have turned yet, wonder how much longer too go, no logs have been kept, so I havent a clue on age.

Thanks for your time,

How would I go about contacting Latewood?
