Not sure if it's the camera angle but it looks like the cob garden looks bigger than the others?The comparison is pretty much done.water level was to high on one side from a clogged pipe due to root mass and the root riot plug rotted the crowns on 4 plants on the right side.pretty pissed off about it.ive been so busy with other shit I didnt have time to micro manage everything.
That combined with the 2 blown bulbs just sucks.
Either way I really think the cobs did better over all than the cmh.i have 3 weeks left and pulled the plants last night.the stems seperated from the rott mass.2 plants under the cmh and 2 under the cobs.
Overall the cob gtowth is more consistent and stacked down to the screen.the cmh is more sporadic.
The cmh plants definitely look better overall but could be because the cobs are brighter therefore putting a higher demand on nitrogen which I cut out alot of it 2 weeks ago.i may run 50 50 nitrogen to part b next run all the way through.
I think his lighting is obsolete imo.the cobs definitely yielded more than the cmh.a 315w cmh is good for a 3x3 that's about it.
It would take 3 315s to cover a 4x5 to compare to 700watts of cobs. Startup cost would be more for cobs but after running both of I had to pick one it would definitely be the cobs.i could cover a 4x10 with 1500 watts and would grow as much or more than 1900 watts of cmh.
If up front cost is a concern I would go cmh .
If it's not than the cobs would be better imo.
People say led doesnt penetrate enough.thats bullshit.i have useable buds down past the screen fat all the way up.all outside colas are as big as the insides.
I think that's the big difference.
3 weeks left to chop.
