anyone using uv in their tents ?

Started one hour and walked it up for a week to 12 here is some pic from this morning. I am ending week 11 of flower, also I chopped one yesterday.

...The entire stem is a solid purple. Holy fuck.

I used the uv for one day to see how powerful it is and it was just as expected I’m not going to be using the uv till later flower last 2 weeks or so but these girls are on day 10 of 12/12 looking very happy so far not to dark leaves but not to light in green

go with 24w for every 6 sq.ft ( 30-40") away. 120-130w for an 8x4, you had double that.

Introduce lightly at a young age to help harden off plants, 15mins in veg to mid flower before bumping up to 1hr a day. 15mins every hour from 12-3.

12 hours per day? Wow....and no leaf damage?

I was planning to follow their instructions of 4-5 hours per day. (Attached)

Can’t argue with results though....your bud looks nice and frosty.

I use California Light Works stuff as far as the uvb goes I have only had it on for two days. One hour the first and two the second. Yes you can tell a difference in production by the naked eye, I will say kinda hard on the leaves.
