I'm intrigued as to how those babes turn out in our climate, I'll be looking in on your journal.
I chose to grow hydroponic drip system in my garage as i have nosey neighbours.
The very best of british to you.
I believe it's 18 hrs of light - 6 hrs complete darkness for the first month, or until the plant reaches around a foot or foot and a half tall, then it's onto flowering.
I'm also from the UK and am new to the grow scene, Rhino seeds is a trustworthy site who also ship worldwide and will get you any seed you desire my friend
