Solo 2 liter hand sprayer.
I have so many plants crowded together it can be hard to reach some. You need a watering system that is efficient. It has to be easy to water your plants or they won't get enough on time. This sprayer is a nice size. Not too heavy to hold. Forget the little cup they show on the end of the spray arm. 99% of the time I adjust the nozzle for stream instead of spray. Very precise application. I am watering the pots and not the saucers and not the plants themselves. Tip can be rotated which is handy for overhead hanging plants. Arm has a sliding piece that allows for different "reaches." Can be filled with tap water - I live out in the country where the tap water if fine for plants. Or distilled water. One could even add liquid fertilizer. 99% of the time I use it just for house plants though I have used it outdoors and for other tasks. Rugged, lasts. I could not be without it. For the very large plants that I have I use an old style watering can. And, since it is a sprayer, it could be used for spraying insecticides. I have those in spray bottles which work well but it is an option. Gene
