Athosanswered grow question 6 years ago
Each LED is different and there is no standard distance like with other light sources (like HID, T5, etc). The answer you are looking for depends on what kind of diodes your model uses (1W, 3W, 5W, 10W) and how hard they are driven (how much actual power are passed through them). The best answer would be to look on the manufacturer recommended distance. But if you can't find it, I would start at 18 inches (45 cm) and see how your plant reacts, does it stretch? Get it closer, day 12 inches (30 cm); Does it show symptoms of heat stress? Try 24 inches (60 cm). What you can do also is try different distances with the back of your hand, if it is comfortable for you, it is ok for the plants and if it is too hot for the back of your hand, then it's too hot for your plants.

Serious problem with small buds.This is my diary https://growdiaries.com/diaries/198497-white-critical-express-super-silver-haze-grow-journal-by-italy-grower
the pistils are turning orange and the buds are small, maybe not enough room? Too much PK? Is it really a serious problem? What can I do? Some advice?

Some guidance for ScrOG please@22cm & preflowering for about 4-5 days. Haven't noticed any stretching (~2-3cm)
When do I start with the ScrOG and at what height should one set the net ?
Also curious about defoliation: Right now, I keep tucking the fan leaves under the smaller ones.

Defoliation (no horizontal room in my tent and a lot of vertical room)This may seem like a dumb question but is cutting these small lower branches off going to promote vertical growth in my plants? I will be doing it later on anyways to eliminate larf but would it be more beneficial now or is it worth to keep to take in light energy for now

Removing of Big Leafs in Flower Phase ????Does it make sense to remove large leaves in the flowering phase to give the plant the opportunity to send more energy into the flowers or should you leave the larger leaves on because the plant also photosynthesises through them.

First Grow Help And FeedbackHello Grower,
OG Kush Flower Day 24: Lollipopped and defoliated 10 days ago. Can/should I defoliate again? The buds seem like they could get more light. Also, I noticed some sprinkles on the top leaves—could this be from too much P/K? Any tips and general feedback are welcome!

Defoliation AutoflowerHey fellow growers,
How should I approach defoliation with autoflowers during flowering? I'm thinking of removing lower leaves, especially near the soil. I prefer to be cautious to avoid mistakes. Reddit wasn't helpful as it seemed too critical. I hope for better insights here.

Defoliation late in flower on Auto'sI like to defoilate, If I were to pick majority of the fan leaves off of these plants being Auto's, will they react or stress too much? I like to defoil near the end of flower to really push all the focus to the budsites. Happy Growing!10 months ago

Remove leaves from auto?Should I remove fan leaves from my auto flower? I wonder since it is so crowded, I worry a bit that the leaves are pressing against the buds. But maybe that isn't a problem? I've read that removing leaves is unnecessary and stressful for the plant.
