I'm gonna take those seeds and put them in the Earth box in the next auto run. I think I'm gonna get a little bit bigger seedling planters, so I can run them until I can sex them without restricting their roots too much, hopefully.
I don't really think it's worth transplanting autos in regular size Earth boxes. I think juniors will be fine since they get that root relationship with the wicking area quicker than a regular. I think a regular would be overkill . Junior I think would be absolutely perfect.
If I time it right, By the time they show sex, their root system is well established but not bound. In the junior, the wicking reservoirs are to the either side of the center line. With the pot close to the same depth as the junior, it will take the roots anytime at all to get established with the wicking area And be well into that Earth box effect by day 21.
That's how I have it planned out in my head!
