looking good bro! i see you have a scrog screen ready as well.
i would suggest cutting those to a 2x2 hole so the buds can squeeze through.
add magnets/electrical/duct tape on the sides of that screen so you can keep it in place :thumbs:
as far as 2 plants in 1 container -- its been done and seen some nice results from em.
i would try to use the same plants to minimize the problems and make sure they are fem.
using different beans/plants can result in one taking over etc.
(man this coffee is just letting me run though threads like theres no tomorrow

)
