hi all im about 5 weeks in to my first grow i have 6 white rhino they are about a foot n half tall and very bushy. im not sure when to put them in to flower because i dont no how long they flower for before they are finished. could someone help me out plzzzz

come on somebody must be able to help me out

start flowering them now as they will double or triple in size once you start your 12/12 photoperiod.

W/R sucks,,, sorry but never did like that strain.Anyways flip them now unless ya have a very tall room.They are gonna grow atleast 2 times the size they are now so your looking at 3 to 4 ft tall ATLEAST when done.Prolly more like 4 to 5 ft being w/r.They like to streach ALOT....

If I was you I'd lst them now and then send them to bloom or you'll waste alot of buds due to light lose.Just tie them off at the top and bend them over till they almost hit the bucket.This will not hurt the plant and will keep them short so you end up with several big colas instead of just one and a bunch of popcorn buds.Just look up low stress training and have at it..... Good luck

thanks mate
