Great thread. I've just bought myself a 315 CMH to replace my 400w HPS. hoping for good things. What is the ideal lamp distance from the canopy?

well, its a preference thing. i keep lights 3 ft above canopy for best coverage, and even at 3 ft above canopy, 3ft plants lower buds wroughly 6ft from bulb are still big.. you can keep lamps much closer tho as these things dont get as hot as the hps.. id say most guys keep the 315's 2 ft above for great intensity and bud swell.. id say at 2ft above the lamp covers a 3ftx3ft area very well,but at 3ft above they cover a 4ftx4ft area.. ive done a few runs now covering a 4x6ft table with 2 315's then a few runs with 3 315's overhead..with 2 i get 800 grams dry, but with 3 i get around 1200 grams.. however i seem to prefer running 2 315's over the table as for some reason i get a better gram per watt with 630 watts,, if i had a 4ftx8ft table i would kill using the 3 315's at 945 watts,,seems 945 watts crammed above the 4ftx6ft table gets great coverage but may be overkill..my best gpw so far was with 2 315's over the 4x6 table,30 plants and yield was 842 grams dry weight in bags...yor going to love the 315,, way better than a 400watt hps or mh

Thanks for the information! I've got a seedling in the tent at the mo under the CDL running on 125w I think, and its about two foot away. I grow in a 1m square tent, SCROG DWC. Going to veg her under 315w and then crank it up up to 380w in flower. I guess I'm just going to have to play around with the light height, but will use 2ft as a guideline. Cheers!

you got it..
im growing a few new strains, sensi's shiva skunk and bomb cherry bomb.. the shiva skunk has weird buds, not very hairy, calyxs look almost like herm bananas but not,,il try to get a pic,,,very weird,,not a favorite for sure.. cherry bomb nice big dense buds hairy n swole with plenty of crystals but not crystalized like the bubble gum.. cherry bomb smells fruity, i got feminized pollen and crossed it with bubble gum, spliff blue berry, and shiva skunk..i also made S1's of all. i think the blue berryxcherry bomb and bubble gumxcherry bomb will be some nice crosses.. in 2 pluss years and 50 different strains still havnt found one better than th bubble gum..

the single plant is the spliff blue berry, it has the velvet blue colors coming nice. on table is 15 bubble gum and 15 cherry bomb, cherry bomb on the right side, its a bit taller and is over growing the bubble gums.. 2 more weeks to go, took cuttings for next run took 16 bubble gums,16 cherry bombs, and 4 blue angels off a 5 week old fem seed mom from freedom of seeds romberryxblue berry, definatly indica dominant wide 9 fingered leaves.. i can only put 30 on the table but i want to put a few blue angels in the front hope it turns out nicely.. ill put up a few more pix after xmas just before harvest, and then again as soon as the next run begins..
question,,, do you think its a good idea having the white horizontal blinds on each side of table? they seem to help keep the plants in the grow area, no branches sticking out the sides, and the last few runs w/out the led's i had a white curtain on the left side but i left the right side open,, the buds on the left side by the curtain seemed fuller than the buds on the far right side.. i thought putting up the blinds on both sides will reflect more light onto the plants,,, thoughts?

saw a spike on the first day of rifle season,, no buck this year, i hunted through black powder season w/ no luck.. my game cam got pix of a few different bucks but no shooters,, lack of snow really messes hunting, as soon as we get snow the deer are seen more often.. every year i get a buck there is snow on the ground by nov.15th this year we didnt get snow till dec.2 i started seeing more deer in black powder from dec 1st- dec 12th... ill get one next year so long as we get snow.. FUCKING GLOBAL WARMING!!

The curtains certainly won't hurt, should reflect light back and like you say, and keep them contained in their area, looks good to me!

how did the side by side go? 2 315's should get better gpw but 2 600's is like 1200 grams if u get 1 gpw.. 2 315's should get around 1,000 grams

I had a ballast fail the other day. So after some pondering. I'm going to dive in to the deep end. I've ruled out DE because of height restrictions. So I'm going to be removing my 2 600 watt MH/HPS from my 4x8 tent. That will give a ballast in place of the failed ballast and one to make seeds with. Going into the tent as replacements will be 3 - 315 CMH. I called my hydro guy and put them on hold. So as soon as I have a few hours I'll go pick them up later in the week. We spoke for a good bit of time about a great many things. I'm not certain but I believe they're the same as used here.

Ive got 8 plants in the tent now just waiting for their new lighting before I flip them to flower. So the first run will be half and half lighting veg under MH and flowered under CMH. I'm still hoping to at least get a glimps of the "better" product. I'll report back in a month and a half or so and give some idea as to what I'm seeing. Most of my strains are in the 10+ to 12 week category. So it will take awhile.

Gorgeous as usual!

I notice you arranged the lights to combine the 315W and the LED output.

I'm curious as to your thinking on this.

What color temperature are the LED lights?

my thoughts were simple,, save on electricity! 3 315's cover the area well but outside rows still have smaller buds,, by using 2 315's and the cobs to the side im saving 115 watts and increasing bud size on those outside rows.. i have 4 100 watt citizen cobs, 2 are 4000k and 2 are 3100k im using one of each over the bloom table and 1 of the 4000k was aded to my veg room... idid 2 previous runs, one w 3 315's and one with this set up, yields were w/in 20 grams 945 watts to 830 watts,,, only a 20 gram difference,,, i think this set up is the winner...
oh just as a note,, i switched my table from the homemade pvc undercurrent typ, to a 4x6 ft flood table, w the screen above to keep plants from falling over,,same size rock wool just not in net pots..this way i can add more plants if i want,,the pvc had 35 plant max,, i think i have 40 on the table now...
