Weekly, remove dead plant material from plants and soil. Watch for slugs and other pests on plants, in pots, under trays, in corners and beneath benches. Sterilize pots and flats with Physan 20 (#7620) before reusing them.
At least once a year, take all your plants out of your greenhouse and thoroughly clean the greenhouse, benches, shelves and walkways. Spray with a hose to remove surface dirt and debris. Then apply a disinfectant (Physan 20). (For TwinWall, rinse with hose and then wash with a mild liquid dishwashing soap and lukewarm water. Use a soft cloth or sponge. Rub lightly only in the same direction as channels to avoid scratches.)
Use Bull Frog Lubricant (#1606) to oil metal frames, door hinges and vents.
Clean glass admits more light and heat. For stubborn spots of algae, spray with Physan 20 or household bleach and let it soak before rinsing. For tree pitch and adhesive residue, use Citrus Cleaner (#1670).
