Chow_13answered grow question 3 years ago The common strategy is measure from the base of the plant to the highest you can put your light. Subtract the distance you need away from the light for flowering for led's its usually 12"( 30 cm ) Then divide that in half. You don't want to Veg your plant any taller then that. Its best to go a bit shorter just to make sure you will have room.Your strain is sativa dominate so it will be taller then usual. Since this is your first grow I would recommend veg for 3-4 weeks then flip to flower. Flowering time will be based on the strain yours is around 9 weeks. Get a jewelers loupe ( 60x magnification) or digital microscope to check the trichomes for the best estimate on when to harvest. If you have any other questions feel free to PM me.
Happy Growing.
