Im in a different situation, im in a more tropical state and dont really have a winter so controlling temps is a battle year round, thats why I like magnum xxxl in 4x4s, theyre great in my situation. Bare bulbs are great if you can control temps, no doubt about that. I dont run sog, its just not practical for me, getting popped with 6 rooted clones under a t5 is worse than 4 5' plants under 2000 watts so maximum production is less of a concern than maximizing what I can get out of 4 plants so im kinda biased in my opinions. A bare bulb 1000 will kill anything else out there if you can control temps and keep it close, if its 4' above your plants its not going to out preform a magnum or a blockbuster at 2' tho, thats my rant, im rrrripped n this took a lot of concentration
