first time grow question

how long should i allow veg? cause i have been thinking like 2 months but i just seen something about 90 days im at like day 28 should i switch to flower soon i also just did the lst to bush it a bit i have a nice bit of new growth in the nodes so what do you guys think??

its really up to you man .. they double in size so make a good estimate as to how much room you will have left before they are done.. post some pics if u can... i vegged my babies for 2 months and im very happy with their size..check out my sig

90 days is probably the quoted flowering finishing time, you can switch to flower when you want, but understand alot of plants can double in size when put into flower so take your space into consideration

Really up to your lighting and your space. Wouldn't veg longer than a month in a half if you only have one light. As short as one week if flowering with a CFLs or a low watt HID.
