Quick question

[Evaldreamar]

Anyone know how long it takes to show bleach damage from led lights being to close cause my one girl wants to eat the light an is showing no damage at all

Couple of days is all it can take (Ive burned seedlings) but every strain and even different plants of the same strain can react differently. Like D.A.S.S. said 18 inches is usually max for 300 watts leds, higher for higher watt leds. Go with what the manufacturer says. They should know what there doing.

Imo those are way to close. I have nitrogen bleaching in my plants too. Im using an 1800 Cob im at 24 inches away and still getting the bleaching. More nitrogen should help combat that too. I bought raw nitrogen to add to my seedling water for that reason.


What wattage output is that light rated at?

'Cept you don't really too much nitrogen in flower, so that could backfire.

Lot of times ,you can't tell till it's already done damage, you sure don't want it to close like that one guy who used to be on GWE, used to tell people to put them 5-6 inches away, he had done ruined his plants ,an didn't even know it. I forget his name.most of the time you want them at least 18inches away.

But he always was so sure that his opinion (on everything) was correct lol

[D.A.A.S.69]

Yeah Aloner, He was a genius, in his own mind. He could do anything, especially if it was different than what was advised, what a nut.

I know they were way to close i just love how it was growing the past ciuple days being close like that but didnt want to push it to long and cause damage i moved the light up lastnight better safe then sorry and btw. Its a mars 300 and a 250 watt 2100k cfl are in the tent at the moment will be upgrading the led to a mars 720 reflector series or a viparspectra 600 par dimmable series its a surprise lol

[D.A.A.S.69]

Glad you raised it, i find they even grow way better when up higher, what you want is good growth, but not too fast, some call it the SWEETSPOT, it ain't hard to find if you watch your plants pretty close, Good Luck Evaldreamar.
