Depth Is What Separates the Botanicare ID 3x3 Grow Tray
ID stands for inside dimension, and that is the whole point. You get a true 36 in x 36 in of growing floor rather than an outside measurement that shrinks once you account for the walls. The redesigned sidewall stands 7 in from the top of the drainage grid. That depth is what takes a bigger root mass, taller pots, or a deeper flood than a shallow tray can hold. Capacity works out to 36 gallons. Outside footprint is 41 in x 41 in x 7 in, so measure the bench before it arrives.
What a Heavy Duty 3x3 Plastic Tray Is Built From
The shell is recycled and recyclable ABS. A core of 70% recycled plastic sits inside a virgin UV-resistant cap, so the surface holds up under grow light and repeated cleaning. Corner gussets were re-engineered for support, which is what stops a loaded tray from flexing at the corners when you slide it. The drainage channels are rounded and wider than the old design, and that shows up on cleaning day more than any other feature. A square drainage grid keeps pots up out of standing runoff, and the flanged edge gives you something to grab. Made in the USA on solar power, and BPA free. The honest trade is weight and price. If all you need is catchment under a few plants, the Low Tide black tray does that job. It costs less and takes less bulk.
Key Features
- 7 in sidewall depth: Takes larger root masses, taller pots and deeper saturation than a low-profile catchment tray can hold.
- True 36 in x 36 in inside dimension: Inside measurement is the honest one, so a 3x3 footprint gives a real 3x3 of growing floor.
- 36 gallon capacity: Enough volume for a proper flood-and-drain cycle rather than a shallow runoff catch.
- 70% recycled ABS with UV-resistant cap: Recycled core, virgin outer layer, holding its surface under grow light and repeated cleaning.
- Rounded wide drainage channels and corner gussets: Faster to scrub between runs, with reinforced corners that resist flex under a loaded tray.
