Ppfd?
What ppfd do you guys recommend for plants in veg? I’m finding that my light can be too strong at max power even at a 24” distance.

Spider Farmer SF1000 or Mars Hydro TS1000?
What would you recommend between Spider SF1000 or Mars Hydro TS1000? Both seems pretty similar, which one to chose? I’m planning on growing two autos at a time/or one photo, 70x70cm space.

Change lights off time?
I'm having trouble with temperature control. My nights get too cold. My current lights off time is 12am-6am. Is it possible to change it? I really want my lights off to be from 9am-3pm. I think that would help me a lot. How do I change it? Let my lights run for 27 hours?

Too little light
I have now tried removing the WPM by smiering 40/60 milk/water on the affected areas. Deep inside the canopy aswell since little to no airflow passes here due to the plant being so deep in the pot. And apart from that the plant recieves 8 hours of light and I cant install a LED.

Lighting coverage
Will my viparspectra xs1500 have enough coverage once these plants get larger? Or will I need supplemental lighting? And if I do need more, am I better off getting the larger model, or just getting another identical unit so that I have 2?

Currently running my KingLED 2000 with both Bloom and Veg switches on. Is this the correct time to go just with the Bloom lighting? There's no harm in running both throughout; correct? Except to the power bill of course. Any thoughts?
