The 600h kit from HLG. Bought it through growers lights. Has a dimmer switch etc.

So far seems to be the best led light we've owned.

Only complaint is the quantum boards are mounted pretty close together. We knew this going into it so the plan was we were going to put the light on a mover and move it a couple feet. Haven't bought the mover yet. That's next on the list.

By the way they aren't that cool when turned up. If we didn't have the fan on the thing it heats up significantly. At least more than we originally anticipated. Nothing like hps but warmer than you might think.
Yes, LEDs get hot. Difference is the heat is above the light and not below, reason for a heatsink to pull the heat away from the diode. I run 5.88" aluminum (bar type) heatsinks from Heatsink USA. I run a passive heatsink, but I also run a fan and they stay pretty cool. Heat destroys LEDs.

Makes 200 Gallons of soil drench, That's one hell of a sample if you ask me. Any other good samples out there you can point me towards yimbeans?

Get a sample bag of the "MegaCrop" 1 part dry nutrient. Free 230g bag for $3 shipping. One of the best 1 part dry nutrients I've ever used. I got a sample bag and have been using it exclusively since. That was over a year ago.
Use "megacroppromo" code at checkout.

Will do, Thank you for the quick reply!

The heat is also more dispersed over a larger surface area, rather than being concentrated around one giant bulb. So there’s no strong hot spot. Still, watt for watt, it’s gonna heat the room/tent about the same as HID.

Lots of folks dont think LED put off heat, but they do. Though it is less heat than equivelant HPS, its still heat. Plus a lot of folks forget to mention that unlike a HPS/MH hood that can duct heat away from the room -most LED manufacturers dont make a convenient way to exhaust the heat from the LED out of your room. You have to cool your room vs exhausting the heat out of a grow room through a duct to relieve high temps. Though LED has afforded me the ability to grow in the summer months, HPS still holds a place in my rooms. Here in MI, I rely on the heat from the HPS to heat the rooms in the colder months.Its a win/win.

@Cheesy Bo' Greesy, how does the Blizzard Bush compare to Purple Mountain Majesty or Night Rider or California Cannon as I have run all those and have a fresh pack of Blizzard Bush?
The Blizzard Bush is a thc bomb. Trichomes everywhere. As compared to the others it has been the most sativa dominant of the bunch ALL three runs (this has been our experience anyway).

Longer and lanky needs extra training/staking and took some time to finish. Nice stone! just wish it had more flavor.

They put off heat but they are more than twice as efficient. 500 watts of my cobs crush a 1000 watt hps with a slightly larger footprint for veg. My ursa's are too strong in the middle 2x2 area where I hit 1600 par easy. A little screen over the middle 4 cobs ameliorates this issue (I have the original versions I am told this is fixed in the new version). That is how they are way less heat. Watt for watt as you guys are saying for sure but you use half the watts.
