Ttystikk's vertical goodness

Hey ttystikk, I was wondering what's your opinion on running 315w CMH in a bare bulb vertical setup?
I currently run 1000w Hortilux in a bare bulb vertical setup. I start with 30" from the bulb and I feel that I only get about 4' of good vertical yield from this single light source.
I thinking that by stacking 2 of the CMH 315's in a tighter circumference, I should get better coverage with a better spectrum.

I think the 2 CMH is a better option, as well as cobs

COBS are the best option, then DIY CMH. you can pick up an adapter from your local Hydro store for $17 for a standard HPS/MH socket to CMH. find a balist that runs 300W. thats the cheapest way, but remember that a 315W CMH covers 2.5X2.5ft so you really need more of them which over all makes it more expensive than COBs by about 3-4 times depending on what youre using it for.

I agree I wouldnt run HID lights anymore.
Cobs for me these days, but CMH is definitely better than HPS IMO.

Should work fine. Stacking three would be even better.

Have you grown vertically in a tent, and do you think it would yield more than a 4-6 plant SOG+scrog under 3x3ft of horizontal COBs?

What do you think about a double sided cob bar and hang it vertically down the middle of the tent from the ceiling. now I've got 4 or 6 buckets and I'd fix a trellis on each side, also hung from the ceiling.

These are some cool ideas- I can't wait to see you try them!

We will see soon enough, Im going to try it anyways as its not that high of a cost... digital ballast though... I guess we will see lol

You'll end up either not stroking the lamp at all, or risking early failure- often explosively. Is your lamp open rated? If not, DON'T run it in the open! The lack of scatter protection will send little burning bits of ceramic pit everywhere and can start fires.

These fuckin bulbs are no joke!

For sure, I have a solid electronics background and to me the difference is silly Look at the running Amps and Volts and simulate the same thing... not a crazy concept.. worst case is a blown bulb.

Ok, low frequency in this case means below 175Hz. Magnetic ballasts do this, but their sine wave output is very inefficient compared to a square wave ballast. Your electronics background should help you connect the dots as to why 315W CMH lights on their proper drivers would be the desirable combination.

did i ever tell you the guy who owned advanced lighting had a LEC explode and almost blinded him? one of the reasons he was so late shipping out my CMH kit.

I hadnt looked into the waves produced only got as far as the power used, but if thats the case then yeah wont work too well.
