problems with plants too close?

Anyone.know of any reason I shouldn't let my plants grow into eachother? Im growing autos that got a little bushier than I anticipated

Poor light penetration if it gets too dense.

No worries of bud rot?

Light penetration is an issue. But the major concern you should have is lack of air flow, which causes bud rot and provides a perfect environment for other fungus and mould. This problem is made even worse when the ambient temp. of your grow room is high. So try and make sure there is sufficient fresh air flow (the tips of the leaves should bob up and down a tiny bit from the breeze). And try to reduce the grow room temp. whats your ambient temperature at right now ? Also make sure to trim off any dead foliage immediately as this will just give more things for mould/fungus to start on.

i got tons of air circulating in there.... also im pretty good about removing the lower fan leaves when they die off.

temps arent bad right now but i just moved my plants back out into the garage. temps have been 50-60 at night 70-80 during the day outside. i absolutely hate trying to keep my grow room chilled right now. its too nice to run the a/c but if i dont the plants get too hot.

i think now the garage is going to be fine. if it gets up to 80 they are going back inside

I wouldnt worry about mould aslong as your air isnt humid. Dry heat and air never hurt nothing, but not too hot ! Removing fan leaves is also fine, better to remove them then let them rot, Char§
