A strain with slow stem growth - like Jack The Ripper - grown in a peat mix will not stretch much in flower and you will get little bud. A strain like Kali Mist in hydro will litterally give you a 3' budcycle from a 3" clone.
3 Kali Mist in the back right (from 1 1/2" - 3" in veg to 30", 32" and 33") - Recycled Deep Water Culture: air pumps and a sump pump for sprayers. The tall spear on the left is Taiga, Big Laughing in front of the Taiga.
