Yes another question

Guys I moved my light closer(150w hps) BC its getting cold and I'm not sure how close it should be any way no signs of heat stress as of now although I just did it. As of right now its sits exactly 8 3/4 inches from the tallest point on the plant I have plenty of fresh air rolling through and temps are dropping below 50 every night outside and some parts of the house (which is when I run my lights) and sticks around 77-80 around the tops of the plants.

Also its 1 plant and a scrog 2x1 1/2 feet net

I ain't no expert, but I think you can put your hands at the top of the plant and if it's not to hot to your hands then you should be ok.
Hth

That distance should be fine in my experience - I have a 250w HPS and keep it at about 10 inches away.

I'd think that would be fine, are u in veg or flowering?

Flowering 10th day

150 watt hps? Your not going to bother it at 6-8 inches with 50f, but your going to miss out on coverage for your scrog.

Maybe purchase an additional light, get some daylight 65k 150 watt LED floods and stack a few around it, you wont have any issues with coverage or heat +/- issues. I run those LED floods as supplemental and the buds grow right on top of them sometimes (they get very leaf happy sitting on them so I know they are tossing out some decent day light spectrum's for the edges).

Thanks for the advise but that's exactly what I've already done just left that info out lol

Should probably switch to COB.

I'm buying a new set in about a month I'm looking at 2 options for the money I can spend one is a 5x5 vivoson tent, 1kw hps from sun system, and two 8in fans the other I'll post a pic of

You won't need anywhere near 1kW for a 5x5, especially with COB. Chip On Board LED. I get trichomes on seedlings with them.

lol, great minds.

Well barring that, you might want to think about enclosing them. I know it might stupid but in a large space like that you loose lots of heat from all the air in the room, just put up some card board or something to help retain the heat in. If things get really cold you can always invest in a brighter HPS, haha.

I'll look it up but what watts am I looking for and I'm on a budget

My heat stays pretty decent with adjusting my light but some nights is colder than other I usually range from 75-79 81 is rare but I adjust when I see that I usually check the room about every hour

Forget your budget, 89w will give you about the power of a 400-600w HPS in a 2x2, minus the heat and electric bill. No shit.

I would beware the LED train, and I love them. There is no magic LED to replace a HPS currently, only the right tool for the right situations.

Legacy LED and COB are entirely different animals. COBs are proven HPS killers.

Do you know a good site that's trust worry and has deals I'll check it out but I'd need two for my 4x4

I have had these trichomes on my plant since day 3 seedling.

You can ask anyone here. COBs > All HID & Legacy LED panels.
