this was an idea i found on a website, just a random guy showing how to build soil beds, not even for MJ. not trying to take credit for it.i have a entire 1.5" layer of 3/4 cinder for drainage, also two drains per bed. much more drainage i have seen anyone else incorporate into their beds... i also put tubes in the four corners of each bed that are buried into the rocks so every time i water new air is sucked under neath each soil layer via those tubes. i think its pretty ingenious if you ask me... i think my beds are pretty "advanced" not just some soil tossed in there.
but the beds have two 3" sewer drains per bed. one RIGHT in the middle of each 4x4 section. i used particle board and a 2x4 going directly across the middle so the beds sag right in the middle towards the two drains if that makes sense, id take a picture but my photobucket is giving me hell, why i havent updated this thread either, im getting frustrated...
i just have a five gal bucket under each drain. also like mention 1/4 yard of 3/4 inch cinder per bed, pretty much enough to cover the entire bottom without being able to see through is what i did... the ON TOP of the cinder i laid some 15 year (high quality) weed barrier, placed the four tubes in the corners for fresh air, then started pouring bags of soil in, starting at the corners to keep the weed barrier in place then kept filling, used 10 bags per bed. i read a thread of someone using 22 bags per bed, how? i dont not know... maybe if didnt use any rock and filled the soil to the BRIM you could stuff that much soil in there, but that a TON of weight after water. mine a bowing pretty good as is.
