Very technical question - LED wattage vs actual power usedMy LED is a Phlizon 600w but the power draw is only around 97w at the plug. Perhaps a silly question, but is my diary entry supposed to be 600w or 97w? Looking at other diaries, it looks like yield is expressed as weight/watt and want to be consistent.Other. Other

Nanners?Can someone verify my latest 2 photos look like nanners? If so, I’d love some insight on why my plants seem to be so light sensitive. Most growers seem to blast their plants with upwards of 200w with little issue. Mine is sitting at 80w 22inches and it seems to be struggling!6y ago

How to switch to floweringIt's been about 5 weeks from germination. I think we're ready to switch to flowering. I'm just not certain on how to go about it. Do I gradually reduce 18/6 of the veg light down to 12/12 (over a week?) then pop in the flower bulb? Or do I just make a hard switch?Week 4

UV rays - Is it worthSo guys, what are your thoughts about UV light complementation?
Earlier this year, I havested an auto flower, and she dind't bulk up the trich production. I ended up with big flowers but with no effect at all.
I was wondering if that has something to do with my light setup.5y ago

Floodlight for bloom supplementI have read that my vipar is not the very best for bloom. I want to encourage and support the flowering with my philips 50w 4000k floodlight, what do you think, will this make a worthy difference? (Until I get a new all arounder light)Week 4

Right lighting at day 6 - fluo or HI as both availableRight lighting at day 6? Very happy that all germination looking good on day 6 from seed. I could either continue with this compact fluorescent bulb (15 cm from tiny first leaf) for another week or two OR switch to full HI 250w immediately (30cm from plant) Thanks!Setup. Lighting

Lifespan of led grow lights?Lifespan of LED quantum boards?
Hi
I'm looking for anyone who has first hand experience with the lifespan of the led grow lights. I'm not looking for the manufacturer guidelines. Just anyone who has noticed any difference in performance from the LEDs over time..

Mars Hydro FC4800 vs FC-E4800FC4800 = 2016 samsung diodes| 2,8 µmol/j |1347µmol PPE -- FC-E4800= 2646 bridgelux diodes | 2,7 µmol/j |1328µmol PPE
Both are 480watt lights...
Is there a difference between µmol 2,7 and 2,8 when it comes to yield?
Is the FC4800 worth the extra money? Doesn't cost much moreSetup. Lighting
