Hydrofarm 3.75 inch Net Cup. Bag of 100, Slotted Mesh Basket

What the Hydrofarm 3.75 inch Net Cup Is Actually For This basket measures three and three quarter inches across the lip for a reason. The lip seats in an opening cut for four inch cups, where a true four inch basket has no shoulder left to sit on. Below the lip it is the same slotted mesh as the rest of the line. Roots leave through the wall and water drains through the base rather than standing in it. Checking Hole Size on 3.75 in Net Pots Measure the opening, not the cup. Boards and lids get drilled to whatever hole saw was in the box. This size exists because so many of them land near four inches. The bag of 100 is enough to fill a board and keep spares for the ones that crack when a root ball is pulled. Anyone working with a board cut for three inch cups should stay with the smaller basket. Key Features Bag of 100: Fills a board and leaves spares for the baskets that crack when a root ball comes out. 3.75 in lip: Seats in a four inch opening where a true four inch cup drops straight through it. Slotted mesh wall: Roots run out through the sides, which keeps a maturing root mass from circling. Open base: Water clears the basket instead of collecting under the medium and going stale. Takes any medium: Clay pebbles, rockwool, plugs and coco blends all sit in these without a liner.
