Parametric fertilizer measuring spoon set

# Measuring spoon set This is a custom set of one to four measuring spoons that are calibrated to your exact fertilizer, plant, and watering requirements. The calibrated spoons ensure an accurate mix of fertilizer every time. **IMPORTANT** you ***must*** customize this thing by measuring your own fertilizer. Every fertilizer blend is different. See the section below for detailed instructions on how to measure your fertilizer. First, measure your fertilizer, then enter both the volume and weight of your sample. Then enter the N-number of your fertilizer (i.e. for 13-3-5 fertilizer you would enter '13'). You then specify the container sizes of water you will mix it with. You can enter from 1 to 4 different container sizes, and the desired dosage in PPM for that container (such as 125PPM). Each spoon will be precisely computed for your fertilizer and watering cans. You can customize spoons for mixing things other than fertilizers too, such as pesticides, herbicides, or fungicides. You still need to measure and weigh the product, but instead of entering an N number for the fertilizer, enter the strength as 100. Follow the rest of the instructions as normal.
