Getting going on week 3. The plants are starting to take off and so far no issues. My res temps are teetering around the 72-73 degree range so I will be adding Hydroguard today when I do my first res change. I may invest in a chiller but at this point I don't want to commit to the 250+ price tag for a decent one. I am also using a hose water meter to get a better idea of exactly how much water this system takes which will help me dial in nutrient levels. I plan on adding a touch of calimagic this week since I am using RO water.
Assuming growth continues at the rate it has been going I will probably top these in 7-10 days. Sometime this week I will be lowering the light and using my PAR meter to get things dialed in, I really want to find the right distance to intensity ratio to help reduce total wattage being pulled from the light. This thing is strong enough that I could just crank it up at the distance I'm at and get an acceptable amount of umols but that is a bit wasteful.
