Second light in one tent
3 fan, 1 carbon filter, humidifier works inside and the tent is 120x120. I have 1 240w qb inside, i like it but i want more yield. So my question is i buy second 240w qb would it be good or it would disturb the balance? Also im afraid maybe electric bill will be too much to hide?

Veg/Bloom switch
My plants are 5 weeks from germination, I have flowers and buds forming but I am starting to worry they aren't growing as they should (I want them bigger). I have had my light veg and bloom switches on throughout. Would you recommend I change over to just bloom switch now?

Switching light schedule for an auto and Phototype!
I'am growing together an auto and a phototype with 20/4 light circle. For my phototype is about time to change light schedule for flowering, will my auto be badly impacted by switching to a 12/12 light? Or should I move every day (same place but no light) the photo for the night?

If humans took weed to grow on another planet where the sun was up for 28 hours and down for 10 hours, how well would it grow? Would the plants adapt to the different light / dark times? Or maybe 24 of hours light, 6 hours of dark? Theories? Earthly Proof? Comments? š½

Que tiempo tengo que dejar mi ventilar encendido??
Can I use the fan in my grow only when the light is on?? I mean, can I set it to turn on and off with the light in the same cycle, or should it always be on??
