Getting ready for my first grow.

Interesting. I just gauge temperatures by walking in the room, and have never felt the need for a thermometer...but I know my MH's burn hotter than my HPS. I've been using the same 1000W MH bulb for quite some time (a generic Sylvania), and have a Hortilux HPS for flower. So maybe that's why I've noticed such a difference.

Guess it's about time to find me a better quality MH bulb...

Interesting indeed!

Well, maybe, just maybe, your MH is up for replacement?
I guess in your example, both bulbs are 1,000 watters?

I take it from the fact that I was able to cool a 400W MH with a 45CFM fart fan... and the cooltube was perfectly cool to the touch.
But the 600W HPS???
Even though it was 200W additional, the amount of heat was totally disproportionate. It was a grow bulb... don't remember exactly which, but it was not a security/HomeDepot HPS.

I remember installing a 300CFM squirrel cage fan to the cooltube (with the 600HPS), and still the cooltube would not be cool to the touch.

And you've never used a thermometer!?
I LOVE IT!
Gotta love growers like you man... really.
I was a freak. I would measure this, and that, and this other things... and the that of this. LoL



Peace Mr. Clandestine!
Best,

I guess I can start off with what I have to work with and then go from there. I'm looking to build my own grow cabinet. I don't have a lot of room so I need something compact and I think a cabinet will work best as I also need it to be semi-inconspicuous. What I had in mind was something along the lines of a 36" wide, 24" deep, 36-48" tall cabinet. I was looking at Rating: 5
