About 25". Yes 2 fans.

Lights are 25"? Not sure if that is enough but sounds fine, maybe heat then

Ok i moved my lights up a bit. Thinking about buying some led’s. Any recommendations on lights. Want at least 600w led’s. Need each light to cover 4x4

I’d get 2 lights that equal that amount
True watts is different than product name watts

Have u used visparpectra?

I’m not a good person for this I’d recommend reading reviews or asking others here. Yes I use led but I’m on my second grow and only know what I have


What u think. Heat stress and any recommendations on led’s

Looks like combination of heat stress and lights too close. Were the leave canoeing or turning up somewhat like a taco shell?

How’s life been treating you? Haven’t heard from you in awhile? Hope all is well!

Are you thinking switch to the LED lights to lower the temps?

Here is the light I just bought @Frescal

They claim draw wattage of +/- 205 but the actual draw wattage on my unit is like 192 watts. The light does a great job and it will cover a 4x4 area

Here is the grow I am using it on

I even talk about the light in my grow journal.

@Countryboyjvd1971 is who recommended this light to me and we are both happy with out purchases. I don’t have any experience with the visparpectra so I can’t offer any input on that

No tacos shells. I’ve been good. Going on second round here. First grow came out ok but i learned alot. Im ready to go at it again. Yeah. Temperatures have been in the 100s here so its been a rough start. Other then been doing well.

excellent @Frescal usually leaves will taco to let you know they are too hot. Keep an eye on those plants and if you see the beginning of something happening start taking pics for me. It could be some type of deficiency but those leaves were too far gone for me to tell what happened to them. I just went off the temp numbers and the light setup and figured it probably was heat stress.

Otherwise the support ticket info looks solid!


Same here @bob31
