INSTEAD OF STANDING IN A CRAMPED DARK CLOSET... and possibly breaking something, or squashing a plant...
Why not just check for light that comes out when the lights are on... DUH!
Not you tnmowtown...
*1. Yes fans 24/7... Not strong, just a gentle breeze, make the fan leaves dance around a little, but not like a flag on a flag pole...
*2.Yes, you can use a novelty green CFL bulb, the output isn't enough to fuck anything up, and they barely notice the green spectrum... You can also find green LED flashlights and headlamps at some hydro shops...
*3.That's not the max temp... The max would be 90 degrees, some say higher, but you're risking root problems... The
IDEAL temp for co2 supplementation is 85*F...
-And keep in mind that co2 is absorbed by flowing over the surface of the leaves, so fans are key...
-Also the higher temps open the pores on the leaves so the co2 is more easily absorbed.
*4. It really depends on your knowledge, what nutrients and supplements you're using, if you're metering it all...
For example;
-If you're just using base nutes at bottle strength, water every other feeding...
-If you are using a rigorous feeding program full of supplements, enzymes and beneficials you can feed every watering no problem...
