Helloo growmies! I've got a question.. I need a new light for vegging (only) in a 80x80cm tent. I am thinking of eather the LIGHTWAVE T5HO 60 CM (48W) or MarsHydro TS 600 (100W) Has some one experience with those lights? Is it worth spending double on electricity with the MH?

Is this a sign of too much light?
I’m noticing the leaves grow extremely close to each other, should I be concerned at this stage, should I pull the light higher back? This is day 3 of week 2, I’m feeding it full advanced nutrients line up for veg. And drying out for a day and a half between waterings

Supplemental light for flowering?
I have a 300w quantum board LED. Its a Mars Hydro TSW 2000. Should I add more light of a different type for flowering or should I just run the LED alone? I've heard people mention the UV-B lights.

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.

light intensity for clones right after transplant ?
basically should you treat them like a early veg ? using migro 4 array and it recommends 40 percent intensity at 35 cm away for early veg. or because they are just transplanted should I give them a lower light intensity.

couple quick questions
Do I need to close the flap to the vent during dark cycles? (Lights off during the day) and should I block lights coming from fan power, humidifier, dehumidifier, or indicator lights? Also do I need to use the carbon filter the whole time? should I ever have the exaust fan off?

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?

I need help choosing a better light for my single plant microgrow!
H50cm W37.5cm L57cm Now using 1 household 13w Phillips LED 2700K for flower, a 120w CFL for veg and I use a cheap 20w dual Spectrum LED that I'm sure does almost nothing. See pics for convo with led sales guy. Is the height really that much of an issue with the light intensity?
