yeah set it to 250w and you'll be fine.I used to use 400w in a 90x90x180 tent with cooltube,that was good too. but either way you'll need a cooltube reflector. without cooltube, temps hit 33-34C easily.

I would say it is way too big. A 200 or 250 watt would be more appropriate in my opinion.

Light for 4x4 tent?
Which would you go with for a 4x4 that is used for veg and flower: Mars Hydro TSW3000 or AC Infinity s44? I've got myself narrowed down to these two options.

Veg lighting approach? Switching from cfl to hps?
I started my second grow a couple weeks ago with a 130w cfl in my 1m veg cupboard. I’m thinking I will make the switch to a 250w hps soon. I don’t want to overheat the space. Do you think this is a good strategy? I’ll flower the autos in my 1.4m tent with 600w hps.

Should I substitute sunlight with a grow lamp on cloudy days?
It’s overcast here today and I’m wondering if I should turn my grow lights on to compensate for the lack of direct sunlight. If so, should I drop the intensity to compensate for the additional natural light? Can you overdo the amount of light (not heat) a plant gets?

LEDs lumens
is there a method (which does not involve the purchase of a rather expensive device) to measure the lumens present in the growbox? I would like to make sure that the LEDs that I bought have the same performance declared on the package 😕

Mars TSL 2000 doubt
I just installed my new Mars TSL 2000 and noticed that some of the IR LEDs are more faded than the others. Is it normal in LED lights? Also the LEDs distribution is different than the advertised. Ripped off or just a different model?

at the moment I'm using a 250W HPS and 2 40W CFL, this takes humidity down. When I will afford LEDs do you think that the humidity will stay as per night or drop down like maximum 10% or it will have same behavior as with hps/cfl combo? Thanks

Light distance and power with a 205W Sanlight LED
Sanlight told me I should use it dimmed at 80% and 45cm when in flowering. I was aiming to reach lower buds so I put it at 100% and 50cm from the upper buds. The tips of the leaves are slightly burned but no bud bleaching yet like my last run (at 100% 45cm). What's best ? Thx !

Need to upgrade grow light
I'm looking to buy a stronger light for around 200$ that can adequately cover a 4x5 space for veg/flower. I've been researching for weeks but can't decide. I'm currently running with two TOAD LED Grow Lights 600W, actual watts 85. They are Blurples. Any suggestions?

What light to plant distance would you set it at? The only test I've done is at 25 inches its stable at 80°f and 75% humidity. When I lower it to 18 inches, the tent read 85°f and 73 humidity. Other question I have is what's your favorite air stone(disk)? Lastly, add c02 yes/no

is the 'greenfingers led grow light 2000w full spectrum' not very good compared to others?
if you don't know the light you can google but there aren't any reviews i can find, compared to say spider farmer 4000 (or others) is it much worse or a little worse, etc? if that much worse when i can afford it someday should i buy another one and count this purchase as a loss?
