My buddy just got a Q. B. with a dimmer, he loves it!!! Did you happen to have the Platinum light height as those instructions suggested? Or did that depend on different grows? Did you get these famous brown spots
View attachment 1078375 I allways get them around the 5th or 6th week into growing? Is that kinda normal for these lights? I use TaNgs easy auto feed schedule with A.N. + 5ml. per. gal. CAL-MAG+ every watering, all bubbled and ph'd to 6.4, in soil- the soil ph is 6.8 on the accurate 8 meter---Full of questions-- i'm getting pretty good smoke, just ugly!!!!Those lights are built like tanks and they are very intense and have a very good 5 year warranty, I have probably asked before, I have just got a strange brain
----it is good to hear from some one that owns a Platinum brand!
It says 18" for the final height--it says 24" early veg- 18" final--- hmmmmmmm----
the tips of the leaves sure are curling up that close, I got them at 20" now---I have been experimenting a lot with these lights, it's just nice to hear from some one with real experience. When I first came to the site I read a thread from Muddy about how to tell when your ready for harvest-- just watch the leaves he said---well, its hard to watch your leaves when they look like mine early on!-----Thanks again for answering so quick-----
