If your growing setup is much larger then the medium and small sprayers on this list are likely not going to cut the mustard in terms of providing you the necessary power and storage to get around your crops without constantly having to re-concoct your spray. However, this 2-gallon funnel-top will do just that. Suitable for use with common fertilizers and pesticides and well designed for easy carrying and pumping, you’ll have your plants treated I no time with this beast.
The major pros of this unit are that: it is actually very cheap; it has an excellent anti-clogging filter; it is easy to clean, and; it is built to last. It also has an adjustable nozzle for different spray needs and either a 12 or 28-inch spraying hose. The cons of this product are that because it is larger it will weigh more to lug around and the locking mechanism which keeps the sprayer going can be a bit temperamental.
