My friend made a homemade version of it. He just got two lbs off of six plants. He topped them and retopped them again and again for clones then turned them over to flowering. Each plant had 15 or more tops on it. He did it all on a 3 foot by 2 foot tote. Most amazing thing Ive ever seen. Was so much vegetation that he had three different fans blowing in from three different angles just keep them from catching mold.
He would have gotten even more off of them but he pulled about 1/3 of the shade leaves off over the last month.
