Well for anyone following along, I've rearranged my room to place my res in a cool corner compared to the hot spot it was at (my water temp would start around 68 degrees and climb to over 75 through the day, and I didnt like that). The temp at the ground level next to the res is 68 degrees. Looks like the right spot.

I raised my growtup up on 2 old phonebooks that were slated for recycling. Procrastination pays off! This allowed me to add about 2 more gallons total to my system, which should also help keep numbers more stable for longer, and temps lower. The exact volume is now 10 gallons. Perfect easy number!

I took a plastic straw and put it straight down into my res, and marked the waterline with a rubberband so now I can check water level very simply.

Based on my water volume and using the "latewood formula", I've come up with these numbers for Vegetative growth:

NUTES*: 10 gallon@8ml/gal = 80ml (1/4 cup + 1.44 tblsp)
*this is for EACH of GH 3 part. Flora, Micro and Bloom.

CALMAG+: 10 gallon@3ml/gal = 30ml (2.08 tblsp)

I've released my attic hatch which allows the warm air to vent naturally, and the ambient room temperature at the canopy top is now at 77 degrees. 400watt lamp is about 14 inches above canopy, and I have cool white flourescent shoplight as side lighting.

As to the PH, it's currently at 6.0 with the plain RO water. I'll nute and supplement it in the morning with the exact numbers above and monitor through the day. PPM is currently at 20.

If any of this sounds wrong or anything, let me know.

Thanks for watching! hehe imp:
