Syringes provide one of the most accurate measurements of your feeds, control solutions, and treatments possible, allowing you to mix as intended for optimum results. These medical-grade examples are clearly and precisely marked, construction is high quality, and they draw and plunge smoothly.
Dosages of nutrients and pest control products can be absolutely tiny, meaning that a slip by just a few millilitres could halve or double the strength of your mix. At best this is just an expensive waste of nutrients. At worst it is overfeeding, permanent crop damage or loss.
