hey all.....
how tall should my plants be after 1 month of growth starting from beans

? i have been growing them under a 400 w mh at 18/6 now for month and they are only 8" tall. i'm just curious if i am on track or if they are falling behind

? i was expecting a faster growth rate. but i am please the the internode growth and the overall health of the plants. i was expecting 1/2" per day but so far i have been lucky with 1/4" per day, and just over an 1" a week

. will growth rate increase once i go to flowering?
peace....
