| does anyone know much about these lights. are they cool or hot. results good or poor?

Don’t be fooled by the 1000w tag. That light only really puts out 118w

COMPARE TO HPS/MH- The 1000W LED grow light can replace traditional 400 watt HPS/MH while consuming only 118 watts! More effective coverage area than any reflector series lights. perfect for a 2x2ft growing area at 24" height.

All those cheap lights run super hot. That light is not 1000w and if I was you I would definitely NOT buy that light. What size area are you trying to grow in and what is your light budget?

im not totally sure but i have 20 big pots. space isnt a issue i have alot. im thinking £60 per light and looking at 4 of them ? oh ill leave that light in the pic and thanks guys for help too

I use a hlg 260 qb for every two plants.

You’ll need about 10 of them for what your doing if you want the plants to produce a product worth putting on the market.

There’s a few things to have in place before plants.

Ventilation fresh air intake/ hot air exhaust

Then get plants in place

If you have 20 large planters and want to keep in veg and not use as a flower room, I’ve seen people use t5’s as a veg light

I would do a lot more research bro. And be prepared to invest waaayyyy more money if your trying to light 20 big pots. Each plants needs roughly 2x2 foot area to itself. You could also calculate your lighting needs by multiplying your SQ FT x 40= amount of watts needed to flower/veg your area properly. Just for reference it cost me 500 dollars to light a 3x3 tent the RIGHT way. If you want good weed, you gotta pay to play. Good news is the lights will pay for themselves if you have a good run.


might do nothing lol. look at these and im a little ebarrased to show these too

22.3c with a high of 30c and 38% humidity and a low of 10c and 18% humidity

@jimmyjimjam check your ph, and place a dome over it. It’s likely curling due to the low humidity. The help ticket info will help.

hope this helps im going to try warm and insulate for the light off period

Combination of almost 20c (almost 40f) temp swings and super low humidity is stopping any transpiration. Gotta get those more stable.

@PharmerBob My grow tent I do it all under the same light. From the time the seed is placed in the soil till I harvest the plants.

It works for me and I also use 2 HLG 260xl rspec for my 4x4. My plants do so much better than when they was under my Viparspectra PAR600 Light.


Your ph in coco should be no higher then 6.0 and no lower then 5.8 to be safe. The low humidity is probably what’s making your leafs curl along with being locked out of the nutrients.

thanks for all help im on it and ill keep you updated i dare not alter ph any more in fear of meter wrong

@jimmyjimjam Just tag me and I’ll be there. I’m on here a lot. I’ve read so much my head is jam packed with info.

I do love my HLG lights. Expensive but well worth the investment as I’ve spent a grand total of $1250 on lights. My HLG lights for both kits what just shy of $799.

DIY route wasn’t an option for me as I don’t have the tools to build a light rig.

If you dont have tools you can get pre cut 80/20 aluminum extrusion, you can get the 3 sided extrusion and use it as a heatsink as well for strip builds.

@imSICKkid I’m happy with my HLG lights. It was very entertaining to put together when you don’t have the space to do so.

If I ever decide to do a DIY kit, you know I will pick @dbrn32 brain first.
