This is my friends plant he got a cutting and has grown it to be extremely big only been vegging a month and half? The first photo was taken at around 4 weeks and the last is the first week its been put into flowering. for the first 4 weeks it was under just 1 600W hps light but 2 weeks before flowering another 600W hps was added it is in a 70L pot filled with hydroton which sits in a flood&drain tray and a pump constantly pumps water in for as long as the light is on Never measured ph or heat ect simply water and feed it plus little bit of topping the photos dont do the plant justice it is up to my chest and is huge will add more pics as it gets bigger but this is going to be a huge yielder!!
