need advice ASAP on growth

ok i have 10 plants i put in my room 2 weeks beofre my second set i put in and they are about a foot taller than my second set i put in . how can i stunt the growth to let the shorter ones catch up..they are in veg still. shorter ones are 7" and taller ones are 15"

Don't stunt them, thats never good!!! instead build a raised platform for the shorter ones.

building a raised platform for the shortere ones what will that do?i want teh plants them self to catch up but how can a platform benifit me

Are the seeds all the same strain?

no they are not the first 10 were half hindu skunk and big shivas the second set are 10 bubblegum

Alright fuck the strains. raise they platform or top the ones that are at 15!!

ok i will top them but should i top them at the very top or choose where to top them because i was thinking about toping as a choice

you could put a screen over the top and ScrOG the entire room or LST the larger ones

whats scrOG and LST

scrog is great because you control the height. But as you learn over time that is possible by tying down and topping. 15 inchs is longer than I wait but top them ever two weeks and you will be very happy

i have never toped before where would you top them at?

Just tye them down so they are the same height.

can i top any lower than what is shows in that example becaues i want to take a couple inch off my plants
