Prime quality cup winning bud has been grown for decades without any UV. I wouldn't stress myself over the specifics because the TS light seems pretty good.
As for the tents, 70*70 for sure. It will be even better if the quality was the same again as the old tents with yellow/green logo. 180 cm high!
Hmmm, but how so? You do know that HID lights emit UV, right?
Anyways thanks for the comments all, much appreciated, but as I said the question was more "what does it do in detail and what does that mean" rather than "does it emit UV".
Cheers
