Help plz

I have 4 marijuana plants in a 1.6' by 1.6' by 3.5' white box with 200 watts of Cfl 2 inches on top of 4 plants. the plants have been vegging for 2 weeks up to its 3rd set of leaves (excluding the feeder leaves) around 3 inches. From here i am planning to go straight to flowering, how much grams can i expect from each plant? Any estimate or prior knowledge is greatly appreciated.

If you go to flower now you can set aside 3 or 4 zig-zag papers. That's about what you can expect.

how long should i veg for?

more info needed for an answer imo. what nutrients are you using if any and what medium are you in? more light always helps your chances. my roommate and I just harvested plants we vegged for 1 month from clone under 550w (~100w per plant) and we expect an oz or so dried and cured from each. based on the amount of
light and size of your plants I'm
guessing you'll get about an eighth per plant

200 watts of cfl is not very much so yeild will be low no matter what and the space you have is really small of 4 plants to really veg youd be better off vegging one slightly bigger plant. I do agree more info is need such as strain, type of grow medium and such but sounds like this is a first so as is I would say going to flower right now a total dry weight if they are all female probabbly in the 1/4 oz area if they are all female but it will be fluffy airy at best.
