| 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. (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.) |
