When I place the light closers than 5-6" she starts to show sings of heat stress.Check out the T5 Club thread. Lots of good mixed spectrum details.
But yes, I mix 25% red bulbs during veg. I like giving more spectrum.
And I put my T5s.....2 inches from plant tops. Close. It won't hurt.
Best of luck.
Peace
When I place the light closers than 5-6" she starts to show sings of heat stress.
I think I will let them grow to the light
I keep them about 7-8"
pending on the strength of a t5 because i have a 100watt t5 and if it is closer than 4 inches it will burn but it also puts out more lumens/watt than my single 39 watt t5 as checked with my light meter but for your veg if looking to dial it in a notch or two more i can suggest a 660-710nm red for veg as this encourages veg hormone (pfr) but will require you to have an ledLook at Cassanderas grow
The link is my status.
.I have a rotating fan on them in between the canopy and the lights but they still seem to cup upIf it does that get the fan to blow between your plant canopy and light. Should stop the cupping if that's what your talking bout... Get that with a cfl when placed close to the lady so I aimed the fan at canopy and all is good now
Hope it helps
Yes it is. And keep some blues on during flower. The same ratio of 3 red and 1 blue.But I'm asking is it better to have 1 red and 3 blue as apposed to 4 blue???
