i had a friend in Ka`u at one time doing raised bed grows. he had a large greenhouse and did all of his pakalolo in the raised beds. they would be totally off the ground in rows and were like 2-4 feet thick, you could see under the beds/open space. i wish i had some pix so could illustrate better, but he used the shade cloth underneath so that the water would be able to flow thru. some of the largest plants i have ever personally seen as the sativas would just use as much space as they wanted. he had trouble keeping things small lol. good luck pepper, looks like the west side
