New light system this week : I went to a MHS Hid 600 watt to a Zeus Lumatek 465 watt LED System.
All I have to say is : They seem to like it after two days.
I stay at 50 % then 75% of maximum light system power for a few days before going full speed !
@Nickname11123, Thx, this is my first grow in 12 weeks without ANY action on the plant structure (no LST, no scrog, no topping, ... ) and they did quite well :)
