Generally only use co2 if you're using HPS bulbs because of the amount of heat stress they put your plants under.

Co2 correlates with temperature not light conditions. 85-90 degrees F. 1200-1500 ppm co2

Ready to harvest?
Hey guys - this is my first ever grow so I'm totally winging it as I go along. Can you see the picture - is this ready to harvest? The trichomes look to be going cloudy to me - but I'm worried I'm just over eager!

Ready to harvest?
I am at the end of week 9 in flowering. The strain is Honey Cream FAST version feminized. I don't give that much water anymore and no nutrients for 2 weeks. Should I cut it all now? Or should I cut some now and some later? (judging by the amount of color) Thank you in advance

Who sells best seeds online? Pic is seeds from local dispensary but have had "femanized" that were hermaphrodite from a few of that brand.
Where should I buy seeds from online? I Googled the highest rated cannabis seed companies but most seem like sponsored articles. I definitely prefer quality so I wanted to see what people had to recommend, if anybody can help would be appreciated. Thanks?

Solenco Mini Dehumidifier
Hi Growers. Please can you advise if this mini dehumidifier will be sufficient to drop RH in my grow tent. I'm struggling to drop RH below 50% and I'm in flower with some huge top colas. Should I reduce light intensity?

What are these white hairs near the flower?
Please see the attached picture. What are these white hairs to the left of the flower? I don't see this anywhere else on this plant, with the exception of one fine strand elsewhere. I do have a dog with some white fur but this doesn't look like his hair at all.
