I augment c02 in flower with dozens of different strains of varying maturity full time @ lights on.
Some are first day in the flower room some are ready for harvest yesterday.
If I dont.....my experience suffers. (of course, in my sealed room right)
using C02 is cheaper, easier, less stressful, more precise than exchanging air here, for me and
after my own comparisons since 2009 I know I made the right choice with it.
I have no concerns with stretch, hermies, C0, 02 depletion.
My recipe for minimizing stretch;
Allow vegetative plant to attain sexual maturity before initiating flower
Keep flowering plants as close to the light source as possible without causing harm to it.
Add controls like AC, dehuey, heat, air flow/exchange for full time atmosphere control.
Sometimes stretching is good momma, I often put a plant under the highest light when initiating flower.
This is fun with a mature multi topped vegging bush, when these monsters stretch(I have 11' ceilings!)
they build trees of bud.
Good advice!
I would like to add that potassium deficiency even mild and unseen will cause plants to stretch. Sufficient amounts available promotes strong stocky branching.
