first off some of you may be awar of hempy buckets some may...i did not start this method...its just something i feel is a benifit to the marijuana comunity asa whole....the "offical" name for this hempy buckets..started in the late 80's buy a guy named hempy hence forth hempy buckets...the system was set up to be simple cheap an ez to use, it requires a soilless medium..there are several ways for this..i use 100% perlite..other include parts vermaculte or coco coir...i use the 100% perlite for its ph nutrality...so i dont see much fluction in root zone ph...i personally use r/o water ped to 6.0 an work from there...but i know plenty of people who use this an dont ph at all...using mixs of coco coir an vermaculte can sometimes shift ph....
NOW ON to containers...the pot or "bucket" for this is typilly a cup or bucket ranging in sizes from 16oz to 5 gal....plant size dectates pot size always...you want a container that has no holes on the bottem...you then cut a small hole opn the side of the container 1-2inches above the bottem ...the bottem inch or so now acts like a mini resivor for the roots to work there way to an soak up...the hole acts like an overflow valve an making sure you dont water log the plants...SO NOW come the point of real terms the hempy bucket is a passive hydro system whose growth compeates with that of dwc/swc...so depending on your final plant size most people use between 1-3 gal plastic trash cans/mop buckets from any home supply store....personally ima sog grower so i grow plants in 32 oz cups then bog those on top of 1 gal water jugs all 100%perlite...your pot size will vary on what you decide you want to do....
ON to nutes....in a system like this you want to use hydro nutes..but organic teas an coco specific nutes work well to...seedlings an clones in small container's need to be watered everyday untill root establishment...after this every other day or so an once you get into bigger containers it may be every 2 days depending on your size pots...the lifting method works well here...in my system i go like this for a feeding schudal...water heavey feed water water heavy feed water ...this keeps salts from building up an cusing problems....now that you know...i would like all hempy grower to post pics an experencies with this system....peace az
