Light distance and when to top?
I'm using a 300W LED. What distance should I keep the lights at now that I've transplanted and the plants are doing well? I'm thinking 24" and then move up as they grow until flipping. Also, when should I top? I've read that waiting for 6-8 nodes is the right way to go.

Mars Hydro ts1000 info
Looking to upgrade my flower tent light to a Mars Hydro TS 1000, is this a good light for a 3x3 tent? It says coverage area 2.5x2.5. My tmlapy 1500w will be going in to the new veg tent. Also, is it safe to swap lights mid flower?

Lux Meter Apps on Smartphones
What are your thoughts on Lux meter apps? The app on my Samsung Galaxy S10+ is showing 16,600 Lux at the tops of the seedlings, and converting that to a rough PPFD shows 222.55/umol/s/m². Reading more, 15k-45k Lux and 200-400 PPFD is good for early veg. What are your thoughts?

PAR/PPFD and light height
PAR/PPFD: does light height matter if your PPFD is in the right range? Another way to ask: is 300 PPFD @ 2 feet the same as 300 PPFD @ 20 feet, or are there other factors involved? (assuming heat, C02, all other non light inputs equal)

Can you make an Auto flower by changing the light schedule?
Ok, before everyone jumps on this with the obvious answer - I understand that you don’t NEED to change the lighting for an auto to flower, but my question is can you, if you wanted to, flip an auto to flower by changing the light schedule to 12/12?

Less light for an auto? Maybe 12/12?
Been going with 18/6 for my cream autoflower from growers choice from Day 1. Now 5 weeks into flower I’m wondering if she would benefit from less light, like 12/12, as you would for a photo period plant. What do you think? Would she be happy flowering in some more dark period?

HLG 550 V2 RSpec power/height in flower
I’m using an HLG 550 V2 RSpec in a 3x3 tent over one Universal Kush plant. Anyone have experience growing with this light in a similar setup? What’s the best height from plant and intensity level should I set the light to? Don’t want to stress her, just want ideal light levels.

How many plants in a 70x70x160cm tent with 100W?
Hello, I have a grow tent kit 2x2 with a 100W 301H EVO Spider Farmer light. I have put there three 11L pots. But now I realize the size/light of my tent might not be enough. Could I manage by adding an additional 60W lamp you reckon or is it best to discard at least 1 plant? Thx
