This system was used two different ways. A plant started from seed was germinated then placed in the rockwool cube in the basket. There was never any transplant shock so the seedling shot off. My plant went 4 foot green giant in no time.
The center of the lid was cut out, to allow for the basket in the middle. The center lid as a result, was relocated to the opposite side of the plant stability pvc pole (for tying up a heavily flowering plants). The lid also aides in the ease of taking nutrient samples.
Spinners around radius and one on the up tube for an added dimension.
This system was then changed. A hole was cut in the lid of a 18 gallon rubbermaid tub. The bucket blaster was then placed inside the cut out tub and received puntcures in the bottom by knife to allow recycling nutrient, to drain further down into the tub. Note THE ENTIRE BUCKET WAS USED AS A FALSE BOTTOM THAT ALLOWED THE NUTRIENT TO DRAIN, BUT THE ROOTBALL TO STAY INTACT ISOLATED IN THE BUCKET. THEN PUMPED BACK UP FROM THE REAL BOTTOM TUB TO POWER SPINNERS
