Botanicare Drain Screen HGC708573 | Fits 4 ft & 5 ft Grow Mod Drain Trays

Botanicare Drain Screen for Grow Mod Drain Trays

Every flood-and-drain run lives or dies by its return line, and one clump of coco can back it up overnight. This is Botanicare's drain screen, part number HGC708573, made for the drain section of their modular grow trays. It fits both the 4 ft and 5 ft wide Botanicare drain trays. On those trays the drain sits in a recessed sump near the middle of the floor. The screen covers that sump and lets water through while holding back grow media, roots and leaf litter. Three punch-outs can be knocked out to pass plumbing lines through the screen. Unused punch-outs stay closed, so the screen keeps its full filtering area. Water passes freely, so the tray still drains quickly after each flood. The part measures about 8.6 x 5.0 x 1.0 in and weighs well under a pound. It is a simple part to keep on hand, because a cracked or missing screen exposes the plumbing to everything in the tray.

Keeping a Flood Tray Drain Flowing

Set the screen in place before the first flood, so loose media never reaches the fittings. Punch out only the openings you actually use, since every open hole lets more debris through. Line up the punch-outs with the fittings before setting the screen down. Check the screen at every crop turn, and more often in systems that run coco or loose substrate. Lift it out and rinse it under a hose to clear trapped roots and fines. Slow drain-down after a flood cycle is often the first sign the screen needs clearing. Root mats tend to grow toward the drain late in a run, so give the sump area a look during flowering. Botanicare's tray cleaning routine works for the screen too: scrub, rinse, disinfect, then rinse again. Keep a spare with the cleaning gear, so a damaged screen never leaves a drain open. It also suits drip setups that drain to waste through the same sump.
