they are Ashanti II (Sensi)
if they are growing at around 2 - 3 inches a day which they are then i guess they will grow at least another 1.5ft lol not sure if i can raise my light any further so i may bend the tops soon, i topped all of them one week into flowering (a) to get 2 nice big top buds and (b) to help stop them from growing too tall. im not going to chop anything though cos i dont want to shock them now as they are doing so well (appart from the height)
