Not sure if it's the camera angle but it looks like the cob garden looks bigger than the others?
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I think his lighting is obsolete imo.the cobs definitely yielded more than the cmh.a 315w cmh is good for a 3x3 that's about it.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.

Cause it is.its been that way from the beginning,fuller branching and bigger roots.it would take 900 watts of cmh ro compete with 700 watts of led In my opinion.Not sure if it's the camera angle but it looks like the cob garden looks bigger than the others?

Hps but it's a different cut that always looks like that.i have 1 ghost and 1 starfighter under them that are the same size as the left sides.plus it's a 1000 watts vs 700 and 630In the last pic, what light is used for the front half of the scrog on the right?
Those buds look the phatest
Yeah I normally top feed the root crowns with hydroguard and remove the rapid plugs before flip just in case.I'm glad I removed my Rockwool cubes! eeek no rot! I can see a tiny little bit of tan starting at the top of my roots just from being in warm air. I'm gonna set my top off level RIGHT below those net pots to see if that takes care of it. I think I have enough DO
But very successful grow Heisen! even with the bumps and missed bulbs

LEC is the same as CMH. Just another name for the same technology.I have a family member who is quite the gardener and he uses LEC. Where do you think LEC fits into the stack...do you have an opinion on them? Just curious.

The clones under the cmh and cobs are all the same.this is really what I wanted to experiment with.the cobs vs cmh.I wud say if u didnt use the same clones for all the different lights then ur experiment is null and void.
I emphatically disagree w ur opinion on hps. Let me ask u this....how many watts from the wall do u pull to cover a specific space? 500w for a 4x4? Is that about right?The clones under the cmh and cobs are all the same.this is really what I wanted to experiment with.the cobs vs cmh.
hps is dead technology imo.i put 2 of the same cuts under the HPS and they in no way compare to the cmh and cob side.ive ran the Scott's under 630 watts of cmh and under 600 watts of hps in the same space and there was absolutely no comparison.the cmh killed them.so watt for watt I'm done with HPS completely.ive already done enough HPS comparisons to waste electricity on poor HPS efficiency.
the 5x10 has ghost og all the exact same size in the same buckets.one side is cmh and the other is cobs.there is no overlap on the ends only in the center.it doesnt take alot to compare the plants under the lights.the lights aren't high enough from the 2 sides for overlap.the light is ambient.In order to extract any tangible data from ur experiment every last factor other than having used different lights has to be identical. Thats including the plants being genetically identical.
The other thing that gives me major doubts about the merit of ur light comparisons is the fact that the different kinds of lights r overlapping one another.
1000 watts a piece on the right side.thise are 1000 watt ballast lol.there is no comparison on par of hps technology compared to cmh or cobbs.i have ran them all with the same cuts.I emphatically disagree w ur opinion on hps. Let me ask u this....how many watts from the wall do u pull to cover a specific space? 500w for a 4x4? Is that about right?
I was asking about the l.e.d.'s?1000 watts a piece on the right side.thise are 1000 watt ballast lol.there is no comparison on par of hps technology compared to cmh or cobbs.i have ran them all with the same cuts.
700 watts on the cobs.I was asking about the l.e.d.'s?
Ok. 700w for what size space? 4x4?700 watts on the cobs.
