Np. and I like your thinking (same as mine .. logical
I did start with 2 Femi to keep it simple as a new grower)
and one plant is enough .. if you can get it to maximum size (even in pots .. might need a bigger one .. or two along the way tho
)
I have had out door plants (in the ground tho) who gave me 2 ponds each !!
do you have nice wether wher you are ? and how about summer length ? do you still have atlest 3 month left ?
do you keep it inside at night for now wile its small .. so you can avoyd bad wether .. bugs .. thives aso ?
do you move it around to catch good sun ?
do you have atlest 5 hrs of direct sun a day ? (+8 would be best)
and I would atlest begin to look in to nutriens now .. need to atlest get some basic NPK (dont your mom/wife have some for her house plants ?)
just start small/low .. wile its small .. up it along the way and keep asking questions ..
I dunno about strain .. look to me like a mix .. but Im no expert atall .. but stavia do grow high .. with thin steams and slim leaves and is more light green I belive .. Indica is a low plant .. with wide leaves .. dark greeen I belive .. will mostly only get to 3-4 foot of high wile stavia can get +8
