I use a pressurized tank that is used for spraying weeds. It has a hose and a wand that reaches 4 feet. You just pump up the pressure with a handle on it and it can hold 2 gallons of water. Just make sure it is only used for water and or nutes and don't try and use one that has had chemicals in it. I have a bad back injury and can't bend down so I sit on a stool and use the hose to reach the soil. They sell them at Lowe's or any big box store that has a garden center and they are pretty cheap. You can get a smaller one gallon one or a much bigger back pack model if you have a really big garden. The nice thing is you can control the output from a fine mist to a full on blast mode depending on what you need. Good luck with the grow.
