I use the ones my Pharmacy gives me when I get cough medicine (Rx). It’s also excellent to spot-water small plants and seedlings when you don’t want to water the whole thing. I’m sure they will either give you one or just charge a buck or two

6 syringes with long blunt needles…one for pH up, one for pH down, 4 more for whatever.
I like the needles for getting past the suds from shaking some of the nutes, supplements.
I’m sloppy when dealing with all the liquids and my poured measurements where never the same…this works for me and my compulsions. 10ml when full, I filled them a few times for some nutes.
