I know that this is a bit of a necro post, but I am planning an experiment soon that may give a bit of quantifiable data for this. I have 40 auto anesthia seeds that I'll be starting within the next week. I am hoping for 24 females ideally. I'm going to grow all of them in 3 gallon Airpots using Growstone GS3 coco mix. Once they are sexed I am going to then separate them into 3 groups. I have a closet that is sufficient size for 8 plants, and that group will get 20/4. I'm then going to split the remaining females between my regular flower room (12/12) and my veg room (24/0). I'll be monitoring and recording height along the way. One question that I have that may seem dumb is this: do autos have an issue with scrogging? If so I may need to rethink the pot size. Also, they will all be getting the same nutrients. I use
Xtreme Gardening's
Mykos and
Azos for beneficial microbes during veg,
Canna Coco A&B, Cannazym, Rhizotonic, PK13/14, and Humboldt's Secret Golden Tree (I've done a couple of side-by-side comparisons of the same setup using Canna Boost as directed and with Golden Tree, to find out that Golden Tree produces the same results). I run drain-to-waste, give a weekly flush (I use the heavy feeding schedule from Canna and this eliminates the risk of salt-lock...might be unnecessary but I'd rather blow 12 days per cycle on flushing as a preventive measure rather than deal with stressed or locked plants). They will be run under 1000W HPS using Econowing XL reflectors (1 ballast/reflector/bulb per 4 plants) and kept to an 80F canopy temp in flower. I supplement CO2 during veg (1000ppm) and flower (1500ppm timed to turn off 8 hours into the light cycle to allow the plant to consume enough CO2 during light to properly transpire at night). I'll be putting a tank and regulator into the closet for the 20/4 ones and will keep 1500ppm for 16 hours with 4 hours to consume the CO2 just like my regular flower room. I'm hoping that the lower but constant CO2 supplementation in veg won't invalidate the experiment. I'm considering bumping my veg regulator up to 1500 ppm for the duration of the experiment (suggestions welcome).
