Adding in an LED board for the last 2-3 weeks of flowering?
Dudders
started grow question 5y ago
Currently running a 400w HPS lamp. Would there be any significant benefit in adding in a 100w LED board on purple or blurple?

No. Just a waste of electricity. Your 400 watt HPS will be far superior and also be completely adequate.

Started the plants off with 60 watts. Increased to 100 watts today with a 20/5 schedule. Could I increase to the full 150 watts already or should I give them a few days with 100? Thanks in advance for any advice. It’s my first indoor grow with this setup and I’m still learning :)

If I move 3wk old S.Diesel & Critical from 18hrs💡indoors to outdoors where they'll get +/-11hrs direct🌞. Is there still a risk of them going into flower even though they're still babies? I really don't want this to happen. They'll be in the woods so no chance to add extra light

Switching light schedule for an auto and Phototype!
I'am growing together an auto and a phototype with 20/4 light circle. For my phototype is about time to change light schedule for flowering, will my auto be badly impacted by switching to a 12/12 light? Or should I move every day (same place but no light) the photo for the night?

😂😂 The heat problem was back... well, now I had to hang the lamp 40cm higher, just put in new poles and made the tent taller. I hope it's not too bad for the ladies. But there was no other way; the temperature at the highest point of the plant was sometimes 33 degrees.

ViparSpectra P600 or P1000?
I'm just starting with a small setup (40x40x100cm tent), only one small plant at the time, but want to be able to grow proper quality in long-term. I suppose the biggest difference between the two lights is the 930 vs 1006 umol/m2/s? Any advise appreciated!

Can anyone explain why all the guides and manuals say that autoflowers need 500mmol/cm2 during flowering while photoperiods need 700, when in reality, under sunlight, the plant in the wild gets 1400-1600? Why not give the same amount of light to plants indoors?

Just wondering if adding sunlight could improve it or makes no difference?
Do you still need to give plants sunlight if they have a tent fan and ac plus led grow lights? I really need to know if after 53 days of 6hours of sunlight daily the plant might be used to the sunlight , although I know led grow lights are like a mini sun inside tent but still?

UV light
Where exactly should the uv light be placed? Is it possible to place it between two spotlights? Or is it better at the ends of the lamps? What uv light do I need for a space of 1m2? I'm very lost, help please! Thank you!
