LEDs for lettuce and microgreens

How far above the plants should these vero 10s be?

Keep them pretty close,4-8" depending on how the heat is.

The room ambient is 78 or so average. I had the leds sitting right on the humidity domes. Didn't melt the plastic but did increase condensate where the lights didn't shine. Anyway didn't get good light spread/coverage so I put them the lowest I could on the chains.

Not sure how much light the domes reflect back or absorb, they need to be removed soon but hoping for stragglers to come out. Anyway I thought the tomatoes seemed tall for having the light right on them



I picked up some maxicrop to foliar feed the seedlings

My room has climbed up to 84 degrees. The lights have been on 24/7 all this time. The 6" x 2" heat sinks are warm to touch and don't want to leave your hand there too long. Probably want bigger heat sinks for constant running, maybe even part time.

adding active cooling is an easy/quick fix for the heatsinks..........won't help your room temps though obviously.

Yeah I'm not too worried about it. Just thought I'd share the info for those keeping up, add to the collective knowledge for whatever it's worth

I have 5 Vero 10s each on their own 9"x1-1/2"x1/8" chunk of flat aluminum driven at 320mA and they are BARELY warm to the touch. What TIM did you use? What are you driving them at?

~300mA. I haven't actually tested them.

Light bleached, not enough light, or deficiency?

I've been wondering about growing a large / tall living tropical vivarium with leds. Somewhere between 6-8 foot tall.

Also looking to light a desert vivarium with them.

Too bad don't have uva and uvb for reptiles. The uv levels of fluorescents fall off in very short distance.
