Thanks everyone for the answers so far. I think I am going on the right track, somewhat atleast.
I am doing after this harvest a repetition of 4 strains, 1 plant per strain. Thats all I can fit.
(All RQS)
Green Gelato : high thc, low cbd, day usage, aiming for an elevated level of cbn in the end product (amber pistils). This I have all ready found to help my adhd nicely.
White widow : medium thc, medium cbd, no medical purpose in mind, getting stoned / maybe anxiety relief
O.G. Kush: medium thc, medium cbd, end of day usage/ anxiety, sleep
Royal Medic : medium thc, high cbd, my girlfriends arthritis relief plant
This what I have come up so far.
