4 weeks of veg 8 1/2 tall ready for flowering????

5 white widow plants are 8 1/2 tall , i know they should be taller but i am lsting them all today is 1 month into veg can i switch to 12/12 or should i wait two more weeks??????

Depends on how much room you got for flowering.

if you have the room go for 2 more weeks! more buds

Marijuana will double or even tripple in size during flower.

ok then im going to wait 2 more weeks the height in my grow room is 5'6

you will be glad you waited.

thanx every one for the help love this forum wayyyyyyy better than grass city ive been giving them there gh 3 stage nutes every other watering

Its said that when its in the flowering stage that it can double to double to a double and a half the current hight.

Tt all depends on how much you want to get from your plants, if you want a larger yeild, veg longer, The longer you veg the more spots you have for the budding to take place.
