Yield Question

hi i have a single plant in a growbox. vegetative part was under 250w MH, 18-6 hours of light shfit, and a fertilizer separate from flowering. all values were ok. after 6 1/2 weeks it was 20 inches tall and i switched to flowering. Under 250w HPS with 12-12 timing it's in the second week. Air flow is ok in my box and the pot size is 18liters. i was wondering if anybody could estimate the harvest weight for me under these conditions?

Mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm Well is the pot from a bag of seed..? or is it good Genetics? Has it been topped?? shooting from the hip done right 2,3.5 oz max "shooting from the hip" and thats with the light being focused right on the plant speaker box size letting no light escape....

Seeds (white widow) were bought from amsterdam, a high quality seed shop, all were femminized.Since I only have one plant in the box, light is fosuced on that plant since day1 and since then conditions are almost perfect.

So you say at the end it will be max 100grams when it dried?

.5 grams a watt

I grow super haze(nice strain)with around 250w of cfl (act wattage).I veg for 20 days and yeild 2oz per plant.I think with your lighting and veg time you could expect way more than that.

ya about .5 too the watt with the right conditions.....
