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

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 ..

Should I do defoliation ? Hulk Berry Auto - 5th WeekHi guys !
My plant is growing so far so good but I feel like she could gain a little bit more height and I could end with a better result with bigger yield if I cut some of the small leaves in the bottom of the plant
Any advice ?
Where should I cut ?

Popcorn/ mini branches keep/remove?Buds are tiny not fattening at week 6. I also have lots of popcorn nugs. Being first growth not sure to remove them or keep them at this late in flowering (week 6), might stress the girls out or might even help fattening buds?
Should i clean up the leaves as well?

Cutting or not cuttingHi everyone,
I’m not used to defoliation and I wanted to know if I should remove the yellowing leaves from my plant. I read lots of things with different kind of view so I’m at loss. The leaves are nutrient so why remove them?
Thank you

Defoliation after LST (week 5)After starting LST on all 5 of my plants I’ve noticed that some fan leaves are still blocking light from new growth sites. The inverse is now also true as some lower fan leaves are now not getting any light. Should I chop the top leaves, lower leaves, both? when should I do so?Week 4

LST or leave them be?Should I Low stress train these girls? I have never grown autos and I am very afraid to stun them. They are ripping fast through water, temperatures are high so they are producing a lot of sugars. I defoliated the fan leaves of #3 in the hope it will grow a bit faster.4 years ago

Remove lower branches on this grow?Should I just remove the lower branches or keep them? They are getting pretty heavily shaded but I rotate the grow bag daily to expose the under canopy growth. This is the only plant I have ever not been able to LST the main Cola, I opted to top it and LST'ed the lower branches.4 years ago

Cut or keep topped branches? (1st day of flower)I have 2 budsites on my plants that I needed to top due to dying growth (either from windburn or trellis net). Both are on thick stems & pass the trellis net. It is now the first day of flower, should I cut these stems back or let them grow out? Maybe cut the one that is “sick”?

Remove lower branchesWould it be beneficial to also remove these lower branches? It's my first grow so I'm not sure if this would be useful. I'm in about week 3-4 of flower, but don't know if this would create bigger buds on the main branches. Experienced growers help me out pls xp
