Not sure who replying to but- going with known COBS/LEDS you know the light and power you're getting.
I currently have one of the Roeladro cobs. My girls have loved it for veg and it was cheap and I got it when I had to setup super fast. Now that I have time I'm going for either Cree or Citizen...
On timber's site look under framework- that has the ready to go, kits need wired and own framing made. You can diy but above my level so once have the funds I'm pretty well set on 2x200w citizen framework setups.
My grow is all legal so no worries there just keeping nosey people at Bay.
I don't see heat being a huge issue as this one seems to out out very little (Roleadro 400w).
If I run the digital temp cut off would I still need dial adjuster to get proper speeds out of the fan?
Lights are the cheaper Chinese led so I give specs with a grain of salt if that helps.
Having a hard time after searching so thought I'd post. Just getting back into things- have a SJ dr150w on my list (5x3x79" iirc). Gonna be running LED- most likely two 420w cob lights for now. I'm stuck on fan size. I'm leaning heavily towards Vortex, just not sure on 4 or 6" and which model...
