Hey guys, just discovered this thread yesterday and I'm pretty interested in the cmh's.
I have a question. Does anybody personally have readings from their par meter on the 630w de cmh?
I got the growers choice in 3000k red a couple weeks ago and also just got a par meter today. I watched the postal carrier toss the package from about 5 feet away onto my step, was not happy. So now I'm wondering if it's even reading accurate or not.
At 33"(how high ive had it from my young plant)I'm only getting a reading of roughly 242.3 umol m2 s1 but the plant seems to be growing atleast an inch on branching per day and stacking nodes about every half inch. At about 17" I was getting roughly 671.2 umol m2 s1.
Do these readings sound right?

That's exactly what my ex wife told me.
She was tough, and she looked at me and said 'get me some pain meds or kill me'.
You getting ultrasound?

No idea about the readings but if the plant's happy, that's what counts!

Yeah the plant has more than doubled in size in the last 7 days and its been under the light maybe 8 or 9 days(31 day old plant) she really seems to be liking it.
I'm trying to decide on going with 4 315s to aid my 630 or 2 more 630s. Grow area is 4'x9'10".
What would you recommend?

It's likely to cost a bit more but I'd go with more 315W lights over the 630W.
My reasoning is that all other things being equal, superior light distribution from more light sources is better. The efficiency difference is negligible.

Yeah I think that's what I'll do. Now to decide what company. I just saw growers house is running a sale on Sun system 315 lec stealth for $260 or I could go with the growers choice 315s for $290. Is there much of a difference? Both were square wave ballasts

Square wave ballast is the main thing. No idea what brand is better.

If a T9 ruptures it will shower everything in hot glass, including you if you are near it. It could also set the tent on fire. The double wall is supposed to contain the rupture within the bulb. I suppose the risk is the same. I never foliar feed near the bulb.

The hot glass isn't anywhere near as much of an issue as scattering mercury all over your plants. Mercury is very bad for you.

Thanks.looks like i got to go hassle the seller,i notice i cant buy a 315 hood either cos it wont take the base on a t9. cracking light,but not worth the risk.thanks for yer time mate.

1.6-2.1gpw. Depending on strain.
My old blue dream cut would pull 9 out of there every once and a while.

Also gotta keep in mind I'm not growing cookies or low yielding strains.

@carolinaDream'n how wide are your rows ? How far apart is each light? Does your split a/chandler the heat ? How many lights? Your space looks almost identical to my new space that is being roughed in now. Do you have a split a/c in each room?

I just read that the phantom 2 is in fact a square wave ballast.
