Coco in air-pot is my style. Perlite not necessary, but wouldn't hurt.

You HAVE to transition with coco in air-pots. Transplanting autos shouldn't cause you any issues with proper handling, but that air-pot is way too big for that plant. I start seeds in coco plugs, and after 4 days (before the roots pop through) I drop the plug(s) into the .7L size. At 14 days, I move them into #2's, which is the biggest you need with autos in coco (4'+ no problem). You just unroll the clump & drop it into a bigger size BEFORE the roots air prune and they just keep trucking.

I did my last run in #5's and they proved to be larger than necessary. I had great results, but the bigger pots meant more water, more nutes & generally more work, albeit less often. Air-pots & coco are a match made in cultivation heaven, but sizing properly is the key. Especially since autos don't have time to fill the pot out, it's counterproductive. Had great yields, but the rootballs weren't as impressive as they were in the proper size air-pot.
