minimum for what??? there is no minimum bro..
I mean.. what exactly are you asking?? like.. is there a minimum veg time in order to get a certain yield??!? or...what?
You don't have to give a plant any veg time.. if you so choose to do so. You can start a plant from seed and go straight to flowering and
skip the entire veg cycle.
I wouldn't recommend this.. as your yield at harvest won't be but about 2 or 3 grams. If that.. because once you harvest your plants..
and you start drying the buds.. they will shrink in size (the buds) while drying.
But anyhow.. sounds like you should do some reading.
If you need any further help, feel free to ask. Good luck to you.
peace
