Sativas & Sativa Dominate

well i was wondering how tall i should keep veg state on, before flowering with sativa plants ?? my space is 160-175cm high
so when to flower sativa?

strains like NYCD, Purple Bud, Willie Nelson, Hawaii strains.

Sativa dominate plants usually triple in height during the first three weeks of the flowering cycle. So ... your veg time will depend upon your headroom.

What ViRedd said. You'll want to start flowering around 50cm high or you can use LST to try and keep the height down.

well because i have growing indica dominate and idica plant's but now i realy want to grow sativas... so i want 150-160cm MAX height sativa so is it still 50cm that heinght when to flower ??

but i have seen about 15-20 cm sativa and at that height start the flowering and those plant's was tall after flowering 170-195cm.. but if the plant is sativa dominate or mostly sativa i can easily grow 50cm and then start flowering... well thanks your answers guys! Peace
