Do you remember what your ambient and leaf temps were before, and after the addition of the CMH?This was the game changing factor for me.
I'm in the UP of MI, (often mistaken for Canadian eh!)...the LED had it's limitations during the frigid winter months.... worked fine, buuuuutttt....when I started "mixing" the two techs, things started getting nutty.
The ladies started doing things I hadn't seen before. Hidden potential I didn't know existed. Eye popping frost.
Ya I’m following some grow logs of different lights. I’ve got a few months at least to decide yet, depending on how I need to acquire itTwo kingbrite 250w kits, or wait for HLG's V3 boards to come out.
If using cmh for flower you would want a 3100k bulb can be used for full cycle or use the 4200k for veg and switch bulbs for flower. I recommend Phillips bulbs seem to be the best on the market I just picked up a sun system 315 it has a dimmer switch on it and the guy at the grow store claims that it is equivalent to a 600w hps guess we will see. With the sun system you can get a 240w version for half the draw from the wall. I paid just over 600$ for mine with a Phillips 3100k cant wait to give it a try.A quick look shows that a 400W air-cooled HID (even a 600W which you can dim to 300W) appears to be a fair amount cheaper than a CMH315.
You stated you wanted the lamp for flower, but my understanding is that the CMH315 is a metal halide (4100k) lamp (typically used in veg), where HPS is 2700k for flower.
Also, most 400W/600W/1000W kits come with both an MH and HPS bulb.
Forgive my ignorance, I haven't done any research on the CMH systems as of yet, so I don't know many details about them.
Brutal man.Leaf temps I couldn't say... ambient room temperature used to be 70-75F lights on, down to 60-65F lights off....in the winter months.
Genuine lol. I know man, I know.Summertime (all 4 weeks) was never an issue, the LEDs killed.
Nice, what do the 4 x 315s and the led have the room at?Hung 4x 315s nearer the sides of one half the room, and a DIY 240W 2x3 strip build in the middle for balance. LUX meter says I got a good 8x6 and maybe a side scraggler or two... Won't be able to run like this by April without AC, so I'll make the hay before the sun shines....
hey run a 600 hid theres to much het to powerloss with a 400 hid,i personally went thru this myself,my 600 is the bomb compared to my old 400,just a thought im still learning,you could also dim down the 600 if need be,good seein ya HustYa maybe but I feel like I’d be paying a similar price to a 315? I don’t have experience with HPS but I’m not opposed.
I think 600w is a sweet spot for hps, too.hey run a 600 hid theres to much het to powerloss with a 400 hid,i personally went thru this myself,my 600 is the bomb compared to my old 400,just a thought im still learning,you could also dim down the 600 if need be,good seein ya Hust
It's been lit up continuously for about 16 hours, floating right around 82F +/- 3....Nice, what do the 4 x 315s and the led have the room at?
Leaf temps are 86ish? That's nice! So they're above ambient air temp. I think getting plant temp up would be a huge benefit where I'm seeing leaf temps of 75-76*F IIRC, that's while the air temp is around 80-81*F...pathetic, no? Haha.It's been lit up continuously for about 16 hours, floating right around 82F +/- 3....
Started zapping leaf temps, those are 86ish, about 3 feet from the lamps, plants are still small...
Pretty satisfying to get a solid 6x8 fully saturated with about 1600W draw, all total...
I've been reading about a lot of people buying that Timber light, I'm sure it's a solid deal. 100w per cob is some intense light. I built a DIY light for my 3x3 tent with 4 cobs that could go up to 100w each, and they were just way too intense for the plants, I had to keep them 3' over the canopy and the tent was only 6' tall. I ended out dimming them to about 75w each and I still had to run them 24" over the canopy in order not to burn the plants. In the end I added more cobs, and I run them at about 50w each, keeping it at about 40w/sf, and they run about 16-18" over the canopy. I'm happy with the results, but I'm just a hobby grower. For me, I could only use that light if I had 8+ vertical feet to work with and/or I don't veg for very long or if I trained the plants (scrog etc.). But that might be more about my limits as a grower or grow style, YMMV.I just finished researching LEDs and I went with Timber’s cobs just based on power. There’s a nice Timber grow light that covers a 3.5x3.5. It’s available in multiple spectrums, so you could do a flowering spectrum specifically. It’s slightly over 400 watts and includes a dimmer.
best of luck in your search! Comparing LEDs is challenging.

Hi. Amigo could you explain a little more what you mean by that please. Im new at this. Thank you .Strip build if you are gonna scrog.
Cob if you're going to grow veg monsters imo
