To cool tube or not to cool tube........ I bought a cool tube and thought I was going to use it and never did. Vertical atleast. Ended up using it in the veg department.

Temps will be fine just wondering about light intensity and bleaching etc

What I'm sure of is that twin 315's in a 4x4 space will do a really good job.

Yeah I'm just unsure of the buds the colour spectrum will produce. Pretty sure I can only get 4200k? in my corner of the world. And I don't want to drop all that coin at once, but I am pretty much thinking of moving in that direction eventually

Anyone running vertical double stacked, 315 watts CMH, on all four sides of a plant ?

Lots of people mix lamp spectrums. I think that more blue encourages shorter internodes & that's about it. It maybe brings out the purples & maroons in maturity a little more

I went from a 1000w hps to a 1000w dual arc lamp & then to the twin 315's & that's what I noticed in the process other than less heat & lower electric bills with the 315's. I'm sure your mixed spectrum setup would work just fine if it doesn't generate too much heat for you to shed readily.

I'm waiting on an email back from supplier about hanging vertical and if it's all cool I'll drop the $400. Figuring it should be all good but not actually sure about how the light fits into socket. Haven't looked into it yet, just looks like it bolts in sort of?

Genuine Philips 315's are U (universal) rated, meaning they can be operated in any position. PGZ lamp holders are a polarized twistlock configuration. Insert the 2 slightly different feet on the lamp into the 2 slightly different holes in the socket & turn 90 degrees clockwise until the pins bottom out in the keyholes. Secure & easy. Piece o' cake once you notice that the feet are different sizes.

PGZ & PGZX lampholders are slightly different. Double envelope open fixture rated 315's will fit both. Single envelope enclosed fixture rated 315's will only fit PGZ lamp holders.

i find it hard to believe a 315w cmh will replace a 600hps and yield the same amount
