started grow question 6y ago
What ppfd do you guys recommend for plants in veg? I’m finding that my light can be too strong at max power even at a 24” distance.

Put your hand under the light at the height of your canopy., if your hand feels comfortable under the light for 1 minute then your girls will be fine. Cheers

6 weeks of veg? I got only 3
Why do i see some auto or non auto diaries with 6 week of veg? When i grew non auto i just had them 3 weeks then switch the light time and changed 400w to a 600w. I learned that because they used to get hella big. And in Auto seeds i switch the spectrum after 3 weeks

Can I switch my lighting schedule ?
Hello everyone. 1st grow here. I'd like to swap my lighting (automatic plants) from [4am:midnight] to [4pm:noon] just to keep the temperature a little higher at night. Is it doable while not hurting the ladies or should I shift it an hour per day to change the cycle ? Thanks !

How to tell if light is damaging plant?
I'm using a Mars Hydro Ts600. Manufacturers advice is to keep height at 12'' minimum above the canopy in flower but other growers report it can hang as low as 10''. In identifying optimum height how would I be able to tell if it was too low for my plants? What should Iook for?

White and blurple led in same tent?
I recently upgraded to a TS1000 for my flower tent, and am waiting on an SF1000D for my veg tent, and now have a tmlapy “1500w” blurple sitting around. Would i gain anything running the blurple and ts1000 in the same tent? Or is it not worth the extra energy consumption

I’m using an HLG 550 V2 RSpec in a 3x3 tent over one Universal Kush plant. Anyone have experience growing with this light in a similar setup? What’s the best height from plant and intensity level should I set the light to? Don’t want to stress her, just want ideal light levels.
