unreal threads man. The number one source of LED grow truth on the web after scouring for the best of 3 months.
Been looking at growledhydro, hydrogrowled, growl-ed and stealth grow which seem to be the biggest ones. HGL have plenty of terrible press (seems just due to the spokesperson being the typical salesperson...enough said) but you used them with a reasonable result, and now they have the 3w models but are on the pricey side. Stealth are well expensive as well and the quality all looks rather similar. Growl have had not too many tests on them from what I can see. Your forum set the standard so will stick with GLH.
Contacting GLH as we speak for a 290 Spectra purchase for 2 plants. The summer has been a nightmare for heat but worried that the night get too cold for ladies at night getting down to about 45F at night in winter. Still, I think a small heater will be more economical than using the 600w as heater as well as light source. Does the 600W GLH produce that much heat that you need to extract a lot?
Also, you dont enrich with CO2 at all? Doesn't seem like you need it anyway?!
Thanks for any info!
Smart move by sticking with the GLH leds, they are the best. Just it was a smart move on ur part bro to stick with what works, their are a ton of great grows on the web using these lights and not just mine. i was just the 1st to use them and i use the more high power ones. i can get you a discount on these also if you say you follow my threads and make sure to tell GLH you seen me post about this. a little something for the support of my threads, i just expect you to join my next grow.lol. na just messing with you bro.lol..
GLH dosent make a 600w anymore , not they have a 500w witch i am about to get in a few days to do a grow with so i dont know much about it. but every light need air to be exchanged its more for fresh air for ur plants and not all about just because of heat. screw those little heaters unless u have a real big room, i use reptile heat lights but the ones that do put out any light, so i only use 150w to heat my room instead of my 1500w heater. its always best to run ur lights at night, this is when its coldest and helps with both winter and summer. either way if it gets too cold during the lights out no matter what light u will need heat. leds do put out heat but its not IR (Radiant) the stuff that HID puts out and burns ur leaves in the hot temps. this is how i am able to grow in the crazy 100F+ summer temps.
i do not use CO2 but would love to see what it can do for me, but my setup really isnt too good and i cant run it in my room.
heres a little something about HGL ( Hydro Grow Led) that you might want to see.

its also funny how she always said 1w leds were the best and will out do the 3w leds any day and now using the 3w leds because of the lights i use have them, if you look real hard most led company's and just copying GLH now, most company's use now 3w leds, 90 degree leds and try to use 11-12 wavelengths. the key thing to remember is that none of these company's can get the same results because its all about the wavelengths used, kinda like a award winning BBQ, you can use the same meant but without the proper use its not going to be the same.
now i dont know about growl? never really seen any grows from them. ive seen a few stealth grow on youtube and i wasn't impressed at all, and it was posted from the company witch is owned or ties in with Advanced Nutrients.. all their plants seem stretched out and their no way that light matches a 600w HPS, i cant stand those claims it makes leds have a bad name

when getting leds look for respected growers and journals to make up ur mind, dont listen to led sales people. the proof is in the pudding. Google my name and you will see even more journals/grows i did and did post on here.
