Personally I would say no..........cannabis plants are "designed" to cope with full sun, all day, every day. I have always run my lights at 100% and with both "veg" and "bloom" spectrums turned on, from day one until harvest day. However, you may want to check the manufacturers' website for their recommendations for the particular light you are using.........some might say 50% for seedlings, 75% for veg and 100% for flowering for example. By adjusting the height of your lights, it is fairly simple to stay in the "safe zone" regarding intensity.........heat is probably a bigger enemy.

LEDs Please help me understand LEDs as mains. Same amount of money I can run double the plants and produce larger sticky buds with hps/mhl combo. I was always under impression LEDS are a just a better florescent.

Cloning area lighting I have a 4x4 tent that has 2 plants growing, and 1/4 of it I wanna create a little box that light cant get out if for clones to grow, and set an LED in there. If I take clones, set my main plants to flower, takes 4-6 weeks, how much light is needed for the clones to survive?

Anyone have any history with vibrating HPS lamps? Mine keeps making a buzzing/rattling noise. I’m thinking it’s the metal inside rattling on the glass so if I slightly rotate it it may stop? What do you think? Thanks!

600w hps Wouldnt let me PM. I have a 5ft long 3ft wide 6ft tall white walled grow room and am thinking about a 600w HPS light now. Will this fill the entire room? If so how many plants should I plant? Will this one suffice? Would a 400w hps be more suitable for this space?

at the moment I'm using a 250W HPS and 2 40W CFL, this takes humidity down. When I will afford LEDs do you think that the humidity will stay as per night or drop down like maximum 10% or it will have same behavior as with hps/cfl combo? Thanks

Hello fellow growers :D thx a lot Firstly, is the reason why my plants (especially cookies) are very slightly curling/folding at the ends of the leaves because the LED is too powerful?(Reason to be worried?) Secondly, should I start adding nutrients? Just 1/4 of Bio-grow for now?

Auto and regular plants in one box.I got an auto plant in a box, waiting for flowering to start very soon. Light schedule 20/4. Now I planted a new photoperiodic seed in a same box. What should I do, keep the 20/4 light schedule before the auto plant finishes and after change to 18/6? Or change it right now?
