Small Perpetual grow indoors, I can help you out there been doing it for the last 10 years
when to flower, very good question and has to be done at the right time
Its best to base it on the size and hight of the flower room and how many plants you have
you want the plants to fill a 1/4 of the flower room when you put them and for them to be at least 8" tall.
With perpetual grow you need to top remove some fan leaves and work hard to keep the plant small in veg
Any less you have a mother plant
(waste of electria space and time imo) but makes thing easier
taking clones a week in 12/12 works well
talkes about 2 weeks to root and then you veg for 5-6 weeks depending on the strain In the flower room
keep plants in smaller pots stunts the growth and help a lot
if you want to reduce the strech in flower repot and flower, don't let the roots any time to fill out
also this gives you more crops per year
