ChemCookies - First Grow

Today begins week 8 of the flower cycle. I lowered the nute down by 100ppm as well as the C02 to 800ppm. I should have enough CO2 in the tank to make it to the end of the grow. 40lbs of CO2 or 394cuft @ $22. Not a bad deal. I stopped using the Streptomyces K61 as they are approaching the flush and lowered the solution temp to 66°F. Nighttime air temps here are in the upper 40's with 40% humidity. The inline AC Infinity exhaust fan is set to cycle to 1/10 for daytime beginning at 07:00. Then 4/10 for nighttime air flow at 19:00. I'll start checking the trichomes closely now. Harvest is soon!
