How high should a 600 watt PHS light be from the ...
Stickanswered grow question 5 years ago
Hi @GetTheGat! You should use the universal hand test, put your hand above the canopy for a minute and see how it feels, if your hand gets too hot, your plants will also suffer. Remember it's easy to burn apical summits with HPS so you better reduce the distance step by step, and see how the plants react. Happy growing! 👊

My method is simple ! Without cooltube 250w (hps or MH ) = 25cm // 400w = 40cm // 600w = 60 cm . With cooltube its more like 15 cm for 250w , 20 for a 400 and 30 for a 600w

40cm or a bit more but it's meant to be close !

When I used to run hps the sweet spot was around 16 inches for the 600 watt. You never want to go closer than 14 inches. I always run oscilating fans between the lights and the plant to help prevent hot spots and burns. Good luck finishing them up!

Well for that light 600 watt HP's you would need to be at least 24 inches above the plants and if they are healthy and taking the light well then you shouldn't need to do much about them and that height. They look healthy and like they are loving the lights and setup good to see cheers ..

How much / often should I be defoliating?Currently on my 2nd grow. How often should I be defoliating? I did a big defoliation at the start of flower, but it seems like after a week they've grown it all back. I'm worried I will stress them out if I defoliate too much. Do I hold off a week or 2 before doing more?Week 10

Near Schwazz Week 6 - AutoflowerMy plant grew massively the first 4 weeks, and leaves became jammed regardless of my training techniques. A medium defoliation, turned into a massacre! Growth slowed last two days - almost up to speed again. What will come of a near "Schwazz" in early week 6 (auto), in the end?Week 6

Looking for pruning/defoliating tipsI have several tented plants under 12 hour light and I am looking for pruning/defoliating tips.
Pics attached. For one, should I take out some select fan leaves to let more light down?? Lots of branches, too, maybe prune some smaller ones?
Thanks for your help!

Late defoliation?I didn't pay as much attention to defoliation during veg stage as I would have liked, instead I kind of picked leaves out here and there all through flowering. Should I have left it altogether after missing timing or as long as you don't cause too much stress it should be OK?Week 14
