Side by side grow. 630 CMH vs 1000HPS

[eyes]

nice job, man. What was the length of those tables? Im guessing 16 feet? also, im looking at your plant spacing and venturing to guess 2 ft between plants?

Air conditioning grows always seem to grow nice plants. Seems to keep the environment right on point.

Hey all I just checked this thread and logged on for the first time in a while. I have done alot of changes to this room and I'm now running 15 630s all together with my other new room. I'm still rocking it out guys. ! Rocking 100s of pounds since this post. The new game changer is the UBV strip lights from California light works. I hang them right next to the 630s and daisy chain them all on a timer. Running about 3 hours during each light cycle the last 2 weeks of flower. 15 minutes intervals every 2 hours. Huge notice in terp and resin production.
I'll be posting more soon and will have a new grow thread. I have never skipped a beat and growing is my life. Happy to see all the comment since I've been gone..

Several philips 315watt CDM/CMH bulbs are available in the open fixture configuration, but only the one designated "Agro GreenPower Elite" (as illustrated in my previous post) is made without Fadeblock. The 942 is also jacketed and suitable for open fixtures, however it does not produce as well as the 930. See Growershouse.com bulb comparison videos.

Forgive the necromancy. But im doing a side by side with cmh vs led.

So i feel it's proper to clear one thing up here thats incorrect

The 2 Phillips bulbs available that are double jacketed most commonly used for growing is are the Phillips agro elite cdm 930 3100k 315 watt double jacketed open end rated
Shown here

This here is the Philips Master color cdm 942 4100k 315 (Also comes in 4000 and 4200, these aren't "grow specific" but work well)

Those are both double jacketed with the UV block (all hid, hps, mh, have a uv blocking outer glass, it stops alot, but let's More then enough through to stimulus ur8 response)

Those are jacket or bulb shape "T12"

The Phillips cmd 315 bulbs that don't have it look like This

Here's a side by side comparison of the 2 jackets
