Changing light schedule
TheSurfBudstarted grow question 3 years ago
Hi, my light is running at 12/12 because i had photoperiod's with them but they are finished now, my question is would it be ok to add an hour each day back to 18/6 without hermi or other issues?
Cheers .

Yeah man an hour day to play it safe , I’ve done similar with no ill effect
HerbalEduanswered grow question 3 years ago
you could either finish your auto 12/12, either switch back directly to 18/6 or progressively if you prefer it prolly won't make a huge difference.
i once had an auto mixed with some photoperiods running 12/12 from week 3 to finish and didn't notice a difference with autos i run 16/8 from start to finish in term of yield, bud density or whatsoever.

Seems i can use both stands at the same time.

Should I only use flower stand or both on? The manual which come with it doesn't tell me this.

Yellowing leaves after first Mainline top. Light stress?Just checking in here, I am pretty sure this is light stress. it was at 18" (specs say 18-24" during veg) and she was likely pretty stressed after having her top cut off!!!
I have raised light to 23". Am I on the right track here?

My grow kit will arrive this week. is there anything I need to watch out for considering the fact that they only have stood by the window (mostly cloudy weather) for most of their lives? I don't want them to get overloaded with the rays of my growlight 😇

ViparSpectra XS 1000 (x2) vs. HLG 100 RSpec (x2)Thoughts on VS XS 1000 (x2) vs. me buying HLG 100 RSpec (x2)? They'd go to either side of my HLG 225 in a tent that's 2.75' deep and 5' wide to 'fill the wings' more evenly. Thoughts on build, safety, quality & heat?

Should I substitute sunlight with a grow lamp on cloudy days?It’s overcast here today and I’m wondering if I should turn my grow lights on to compensate for the lack of direct sunlight. If so, should I drop the intensity to compensate for the additional natural light? Can you overdo the amount of light (not heat) a plant gets?

Swapping lights during floweringDo you guys think that swapping lights at the late flowering stage is going to harm my girls in any way? Been fortunate enough to be able to order myself a Viparspectra xs4000 to replace the v600. And as I understand it should be quite an upgrade.
Thanks for any advice!Week 7

Set Up TentHow should I set up my carbon filter, exhaust fan & air ducts? I’m in limited space right now but want to make sure I get good air circulation still. I set it up the wrong way the last time I had it up but it was already up so I just left it. Also, my fans. Where should they go ?
