So whats your rule of thumb for your wattage per sq ft under leds? Maybe I'm just over saturating my plants with the lighting. My flower light is at 50 watts a sq ft with the supplemental and about 41 with just the strips,Yeah man look at the purpling on the stems,Phosphorus without a doubt probably locked out from the absence of calcium to move it through the plant.Your LEDs are probably more powerful than you think and its putting the extra strain on the plants uptake.
Do u shoot that Co2 during veg or flower?Yeah man its 16x15 feet with a 24K mini split,RO system and CO2 controller.I built it specifically for this purpose.Has an exterior door on the inside that seals the room nice.I can get the CO2 ppm up to 1000 just breathing in the room come back an hr later and it only drop down to like 980.
I went through alot to seal it all up,moisture proof sheetrock,plywood ceilings to screw my fixtures in wherever i need them,several 30 amp outlets and everyone of them has a purpose.Bright as fuck painted walls with elastomeric.I put alot of thought into.The Veg room is next to this one but im still working on it.Will have 27 4 gallon buckets for starting plants.

Yeah im pretty dumbfounded by this entire comparison.COBS and CMH are where its at.Im pulling the HPS out after this grow,I doubt i will ever run HPS again,Not when i can get 1000W CMH in 3100k full spectrum.Just to clarify the left side on the last picture is the cobs and cmh(hps till new cmh comes), and the right side is the hps and normal mh?
Assuming that's right the cmh/cob side is blasting ahead with the stretch. This is gonna be a damn good show to watch. I can't wait to see how things look in the next few weeks here.
Lookin fantastic bro. I would love to see those done with a DE hps as wellThere flowering up pretty good,no difference at all between the cmh and the cobs.about the same stretch and node stacking.
HPS is dragging ass compared to the other side but is at 980 ppm stable and the cob and cmh side is at 680 stable.crazy shit.

The next run will be 1 side 1500 watts of cobs vs 2 1000w nanolux DE CMH.ill have 6 strains on each side all clone only strains,wedding cake,wifi 43,gg4,sour dub, A dub and purple punch 2.0..ill run them from the get go and see where it goes and weigh the 2 plants from each side for final comparison on weight,color and trichsLookin fantastic bro. I would love to see those done with a DE hps as well
Valid point. And the price of DE hps is already reflecting this. I'm now seeing 1000w gravitas for £200 brand new lolI would run the DE but I cant justify buying them just for a comparison and them selling them after.i think after the new DE cmh 1000w become more widespread they will make de hps obsolete.like the old mercury vapors and t8s
I can take measurements later and give an average node distance from each light,I think stacking may have more to do with lights off temps and kelvin rating,but is still interesting,I dont see any difference between the CMH and COBS on node distance,The HPS is a little closer stacked.But it does appear that the HPS side is about to go ape shit.I’m interested to know about stretching and stacking, if one lighting technology minimizes/maximizes them. Thanks for doing this @heisenbubble
Im not sure why.You would think that more PPM means more growth.It has to do something with the spectrum is all i can guess.Fuller spectrum is encouraging more growth with less required nutrients.
