Does this look ok? I have 2 plants not growing as fast as my macchiato plant. The other two are different strains, Runtz & Zittles. I don’t want to over do it but I know light is key so I thought I’d ask. Both 1000 watt uv & the other is led. I’m on veg week 5 of all 3.

78,600 lumens at canopy, ok for pre-flower and flowering?
I have recently received a lumen meter. Measuring 78,600 lumen over canopy, is that OK? For my other grow, does anyone know how many lumens seedlings need (at about 25000 now) ? I can convert from PPFD or PAR. Educate me! Thanks

How to reveg plants after preflowers by the end of april outdoors?
How big are the chances to bounce the plants back to veg after preflowers by the end of april and 14h of day length? Mostly cloudy weather, warm day temperatures (30c) and cooler nights (8c)in the old greenhouse simulated probably to much end of summer vibes.

How to tell if light is damaging plant?
I'm using a Mars Hydro Ts600. Manufacturers advice is to keep height at 12'' minimum above the canopy in flower but other growers report it can hang as low as 10''. In identifying optimum height how would I be able to tell if it was too low for my plants? What should Iook for?

NEED SOME ADVICE! Change to LED from HPS? which ones are good for tent size? Which ones are good for good yields?
I've got a 4x4 tent with 8 seedlings in cups but will be in 11L pots. Currently I had a 600w HPS light but my ballast busted today. I have a back up CFL 150W not to mess up the light schedule. Thinking about changing to LED lights, I know it'll be cheaper but I want same yield...

How much light does a seedling need?
Is there a limit to what it can use? Could an LED grow bulb a couple inches away provide enough light? Up to what age? Thank you so so much. My first grow and I really appreciate it! Specifically this one https://www.gelighting.com/led-bulbs/e2624/ge-grow-balanced-spectrum-br30#

Changing light cycle on seedlings?
Can I run autoflower seedlings under 24/0 light cycle until they reach mature veg stage, and then move them into an 18/6 light cycle? I’m starting seedlings in a space tote, then transferring to a large tent to mature. Will the light cycle change have negative consequences?

General question about raising lights.
Gotta question for what most of you are doing to raise your lights? Currently I've just set it static and move as needed. But I'm curious if anyone has a easier method or know of anything made to aid in the raising of the LED light fixtures ?

amount of sunshine for autos in late flower - open air, outdoor grow
We're getting 14-15 hours of strong sunshine a day. Now that I'm late flower, should I move my autos into a spot that will get shade for half of the day? Seems like they may not need to be pounded by this much light/heat at this point and could use more down time.
