I guess everyone is sleeping
I am in the same boat as you so I will be looking for answers to your questions. Happy New Year

5 or 6 weeks veg from seed and bud em for a metre.
Sativa's grow very tall and fast. The plants will double in size during the first two weeks of budding.
If they get too tall just stake the cola sideways so it still gets light.
Also be prepared for 13 weeks of budding.

Strain?

Silver haze #9 is the strain pal iv put them in flower already at 5 cm tall because they veg and bloom at the same time on 12 12 coz that's what there used to growing near the equator

those hazes you can grow pretty much 12/12 and get a meter tall. i'd say veg them to 1 foot tall and then flower

A meter fine by me any bigger then there might be height issues i 12 12 them at 5cm pal

Only have 2 metre of height in my tent
