Yes..leds are cheap now, and rotating devices with lights...I think they are prone to accidents...

Long time ago, circa 2002 leds were so expensive that I thought that as they weigh a little..I could use less leds by rotating them in a circular way over the canopy…. in order to acomplish that I use a rotor, in the axis of the rotorThere was like a big horizontal fan Blade...well too much for...

Use the lights at night time, use leds, use high light intensity cause it allows the plant to deal better with high temps...Anyway 33-34 Celsius is a lot, you also need to learn VPD concept and increase the humidity according with a good VPD chart. Also you better grow sativa strains that are...

R.I.P .Condolences to his family and friends

I only consider S1 if is the only way to preserve some special genetics…

Lucky you...but S1 for me is not the way to go

I think the same happened to me but by chance...:) unknowing the real reason

Also it should be keep in mind that at low temps, photosynthesis rates go down...so the plant use less nutes..so a kind of equilibrium much be reached….
