I have an oscillating fan blowing across the top of my canopy and a fan on the floor blowing up through the canopy. Fan on floor brings the cooler air that sinks back up and also co2 is heavier than air so it helps to blow the co2 back into the canopy. Good luck, hope this helps!

I keep a 20" box fan running while lights on at low speed from week 1 on. Its pointed directly down on my plants (with lights in path). I find most people will use fans from the top or side of the grow. A fan will add heat to the grow space, but the benefits of air movement is greater.

Popcorn budsThis is my OG Kush outdoor grow. It's kind of a side project. Fed regularly with fox farms liquid nutes. The summer was pretty warm and humid. Will these fatten up or am I stuck with popcorn buds?

Defoliate?Hello! Based on these photos, should I defoliate any more? She’s an auto, 8 weeks, 20 days since she entered flowering. I just don’t feel like she’s putting as much into the buds, but I’m not sure. Recommendations would be so so appreciated!

Pineapple Auto - Can it still produce some decent buds?Hi All,
I'm a complete newbie so thank you in advance. So long as I have my grow dates correct... my Pineapple Auto is it 75 days and looking like it could be several more weeks till harvest. Is it possible for some autos to take 90 days or so?

Popcorntopjes op 1 plantHallo,
Iets raar, ik heb 5 autoflowers en 1 plant staat heel hoog en vol met mini popcorntopjes geen enkele dikke top, de ander 4 vol met dikke toppen. Hoe zou dit komen. Heb ze in het begin wel getopt. Kan dit een reden zijn?

Nitrogen overfed on flowering stageHi
My grow seems to go deeper into nitrogen overfeed that I cant do much about, the soil i bought seems to be PACKED with it. Flushed a couple of times, and no result. I get leaves, not buds.
I’m on the 8th week.
Can i still save the grow and try to re-pot in neutral soil?

Autos - pistil colour, timing, and bud expectationsOne of my autos is seeing a lot of pistil colouration already. I am in approx week 4 of bloom. Can I expect more bud growth, new pistils, or is this a sign that this is more or less as big as we're gonna get? I know with photos pistils can appear in waves as buds fatten. TIA
