greenhouse

please, all info on greenhouse growing. i have 2 female lowrider and 3 female bubblegum. how long roughly will each take to grow. it is spring here in the uk and seeds are germinating. i ave no control over the daylight so i'm sure it takes much longer than indoor grows. greenhouse gets the direct sun for about 6-8 hours but its light for rest of day. any advice would be great

it depends on where you live. whenever the days are 12/12 it will start to flower. also make sure that it doesnt get to hot a non vented greenhouse can get real hot in the summer
