I still like the CMh and im not discrediting them,I was just posting a pic of the side by side of the plants in the same system.I thought it was interesting.I can move the plants in closer and shrink there scrog but they wouldnt yield more than the cobs in a filled out 4x5.I think watt for watt the cobs have the edge and thats just my opinion.Im in the grams per watt game as others are in it for a different reason.Im going to order the 945 CMH with the square wave ballast and put it againt the cobs on the next run.
Ive seen the 860's but didnt know if they was square wave or not thats why i only got the 315s.The bulbs are pretty new.Ive ran them on 2 runs so far not counting this one.
I like your COBs, they give excellent very even dispersion with the multi-lite points,
Ive run a $20 GE 1000w MH against a 1kw HPS horti-eye and the $20 GE did what the $100 eye did
so ran those for quite a while. strains has a finger in the pie also.
I'm convinced the Kelvin figure has a lot to do with it and 4000K is the all around sweet spot imo.
like i said it's no coincidence the CMHs are 4000K.
my cdm-cmh 860s were the best Ive seen for healthy plants
but running a 6000w bloom room I was was coming up short to the tune of almost 1000w using the 860s.
I'm now using E-series gavs now for the powerful penetration, they are rocking for sure.
It's good thing experimenting, without it where would we be.
it's exactly how I ran across the $20 GEs trying to give a more balanced spectrum with the HPS
using 2 bulbs side by side I noticed the $20 Mh out performed in the yield dept on a certain strain.
I really upset a lot of apple carts @IC Mag with my results.
anyways It's all about the pro-n-cons of a system and they all seem to have em.
