20 or so days flowering

heya guys im back with a new grow box and 2 flowering plants just wanted to c what your thought any advice complaments lol will be nice my box is 2 metre high and wraped in white panda film it has a 250 hps light running inside with the fan on the side that blows air in the one on the ground that circulates air and the ducting with a fan in it to blow hot air out. i also have 4 cfl lights that i can put for side lighting but the 250 hps looks like it is enough 4 my girls what do u all think?? the plants are doing great and the buds are coming along get am planning on setting up a grow room with 2 600w hps lights next after these . so a couple questions how much longer do u think these will take to flower . and what would the yeild be any estimations would be great as this is my first time growing this stain . soo thanks for looking guys think its about time to water my girls thanks for looking
KEEP SMOKIN :jointsmile:

Nice Healthy plant's!! Good luck with your finish!...Later

Hey thanks for that man hopefully they stay nice and healthy. what yeild do ya rekon i will get of each plant (estimate)

This time with the 250hps @ cfl= 3 to 4 oz. a plant. Next time if you get the 2 x 600hps = 10 to 16 oz. a plant. Hopefully you have everything else worked out? Good ventilation is just as important as Good Lighting! Good Luck, They look Good so Far...Later
