@Gentlemencorpse thanks man, yes probably best idea for this first grow (2nd actually but was long time ago), will go for just LST to see how it feels like. Also would love to have a not too long harvest so wuld like to avoid long vegetative phase therefore avoid topping.
got 2 sativa dominant (lemonkush headband) and 1 dominant indica (pineapple skunk)
and how about the 4plants option? that doesnt include any sort of training?
yes you are right not much height available
@Boatguy thanks for sharing, that was helpful, might be a great option for future
