i have a 20 pound co2 tank and the hydrofarm small room regulator.

my space is 3x3x6 = 36 cubic feet, so what should i set the CFH flow meter to? my model goes from .1 to 2

how long should i run the cycles for? the timer that came with it has 15 minute periods, but according to the online co2 calculator i should only be running it for 3 minutes.

should i run the tubing above the canopy or into the scrog screen?

is a 400 watt MH light enough to reap the full benefits of co2 for this space? i can add another 250 watts if neccesary.

should i be running exhaust cycles at all?



also: in the instructions it says to run the system for 3 hours continuously after the lights come on, should i do this or stick to a shorter cycle?


any help would be greatly appreciated :hippy:
