Yes its an 8x8 tent they have remained in same space whole time so far hadnt got the other tent to start a cloning process. Temps with all three lights been 82-68 humidity been
65-90 lately i mean i just cant figure it out. Usually thought plants wld show mildew or mold and have water on ceiling but none
What is the lung room temp and humidity? I've seen bud rot start at 65%

When does mold and mildew really start to take toll, like its only been one week into flower no signs yet and i just started running all 3 lights. So before it was just the one with all the AC going and fans. Numbers were good.
I got mold at 45% humidity. The air was 45% but inside those fat buds was almost 100%. Actually I think that was when I got the bright idea to turn one of the fans off. Anything over 60% is tempting fate.

The tent is in my garage Temps usually 80-71 and humidity 35-50
Somethings not right with your airflow I'm suspecting. If your feeding your tent with those numbers and exhausting outside i think you should be able to control humidity better. You running your 1050cfm fan at full power? Have you checked for leaks in system and any bad kinks?

Also is your AC in tent or in garage when running?

Its inside the tent exhausting hot air from AC out.

I cant figure out your airflow inside the tent....the cold air comes out the AC, right next to an exhaust filter on the ground where it is sucking out the rest of your cool air.
Then you have huge bubbles of hot humid air around the lights, and how do even get any circulation? Blowing hot air around the upper canopy isn't going to do anything. The air is stratified.
Try to get the filter/exhaust up higher and get a fan to blow that cool ac air into your canopy, then put a couple rotating tower fans in the corners.

I 100% agree!

Personally I'd run the AC in the garage and control the air feeding the tent. Also where does the exhaust from tent fan and AC exhaust to? Not into the garage correct?

Finally got the numbers down fellas i was just running AC with lights on and dehumid after lights went out, i know ass backward now i got it running with Ac and lights on. Numbers good for as many lights in an 8x8

Next battle will be height of plants in here, i going to use net and bend down and i also can take lights up 6-8 more inches
When did you flip those? The stretch can be real. lol

I had some GMO (skunkmasterflex cut) plants in this run and I was told they are 12 week plants but I didn't know that all those extra days of 12/12 would be spent in stretch! I thought they would just take longer to ripen or maybe have the added time spread throughout the 12/12 phase. Nope, all in stretch lol and an aggressive stretch at that. At day 42 their flowers looked like my glue does at day 28. If one started that plant a few weeks earlier it could take that veg time in flower and save a few hours of lighting. Dialed in it could be a sweet strain as it's potent and has excellent yield potentials.

Renfro my guy Im scared because this is due to me being greedy, i flipped 9 days ago the plants themselves are 61 days old from seed. They still have to go 8-10 weeks. Will the net and 6 inches of space help or pretty much am i just going to just have to see wt happens???

Of course it will help, but will it be enough? Time will tell. Some strains stretch a lot and some don't. If you had more area I would scrog them out sideways really aggressively to make them wider and shorter. Starting to get late for that though.

First harvest always the toughest most unpredictable one after this definitely will have little more figured out. That gorilla tent 7"11 ceiling looking real nice now lol.
