Great shots man. I have done a couple vert stadium grows and man are they a blast. I haven't surrounded the bulb this way BUT it looks perfect for penetration. I think the only thing I would add would be a vertical light mover, odds are needs to be a diy job though lol
Trichs will tell you a ton but check from multiple bud sites. I really go by the bud swell itself because sometimes you can have a decent amount of amber but wait just a few more days until the buds actually swell up is the way I go. Now there are some sativas that are just airy and I just go...
