Well as promised here are some pics of the massive 7-8 feet tall Jack Herer. They are so big that I cant really get into the room to take a decent overall pic of them. It is an 8 foot high ceiling and they have grown past the lights. The room is about 6x4 metres and the plants have grown from wall to wall. Most of these pics were taken by standing on a chair and others are taken by kneeling down under the canopy. There is only 4 plants here Instead of putting it next to a normal soda can to compare size I got someone to hold up a 10 litre watering can.
