Equipment: rubber gloves, washing up sponges, bleach, 35% strength hydrogen peroxide, a soft fabric cloth, a dustpan and brush, mop, bucket, hot water.
Empty your grow room or grow tent. You can keep lights and hanging stuff in place—but be sure to clear the floor. Grow trays, free standing fans, reservoirs, pumps, root balls of harvested plants, everything like that must go. Sweep any debris off the floor
Mop bleach solution: Add three quarters of a cup of strong bleach for every gallon of water—that’s 50 mils per liter.
Clean your reflectors, inside and out using a soft fabric cloth—not paper or abrasives. Use a 3% vinegar solution and rinse with distilled or reverse osmosis water to prevent calcium spots. Check for dust accumulation on top of your reflectors too, and use a standard window cleaning product to buff up the glass panels on air-cooled hoods. Verify that the ducting connections are secure. Consider the age of your lamps and whether they’re due for replacement. You can watch my video all about that here. Otherwise give them a wipe with a dry cloth.
Irrigation and growing systems. Hydrogen peroxide solution—2 parts water to 1 part 35% hydrogen peroxide.
