Greenhouse Accessories will enhance your greenhouse growing experience. Depending on how your greenhouse is used most people will find that a minimum list of supplies is a heater and a ventilation system. This all depends upon the plants you are growing, what time of year you are using your greenhouse and the climate you live in. Greenhouses will not maintain heat overnight in the winter months. Greenhouses will build up heat during the day in the summer months. The next item of general importance is shade cloths and automatic roof vent openers. The automatic roof vent openers are solar powered and require no electricity. These are an inexpensive way to cut down on summer heat. Shade cloths are available in knitted, woven or alumitex fabric. Different shade percentages are also available. Our greenhouse benches come in fiberglass with UV protected tops. Propagation mats are an essential for seed starting. The even gentle bottom heat will help your seeds to germinate. Circulating fans keep the air moving in your greenhouse, and give you stronger and healthier plants. We suggest adding these accessories as you find that you need them. We do strongly suggest that you get a ventilation system at the same time as your greenhouse, as you will need to do some retrofitting if they are purchased at a later date. All of the other accessories will not be attached to your greenhouse frame.
