The most common greenhouse growers supplies are garden tools. A spade, trowel or small shovel is the most widely used tool, it can be used to pot and transplant plants, add fertilizer and till soil. They are usually only big enough to hold a couple of cups of soil, have a pointed tip and a durable handle made from wood or tough plastic. Wooden handles tend to crack and break when exposed to the elements, so either keep it dry or use plastic trowel.
Other greenhouse growers supplies are durable gloves, a watering can or special hose attachment, and plenty of extra soil and fertilizers. Fertilizers are important in greenhouses because of the limited space. The soil often does not get to rotate and aerate properly between crops which drastically lowers its nutrient value and slowly makes it ineffective for growing unless it is replenished with the correct amount of fertilizers.
Other useful greenhouse growers supplies are various beneficial insects. A natural ecosystem is healthier than trying to use pesticides and other chemicals to control pests and mold, which can ravage greenhouses closed environments. Aphids are a common problem which can be remedied by a number of beneficial bugs such as lady bugs. Many nurseries sell beneficial insect larvae.
