Never used dry fertz before. I need to add very little amount (as little as 0.1 gr...) . Any recommendation on where and what kind of measuring tools to use to dispense such small amounts?
If you are measuring using teaspoons, you can get measuring spoons that go down to 1/64 on Amazon (I have heard people getting them from stores such as Bed, Bath and Beyond as well).
If you want to measure weights, then you can just get a kitchen scale that measures to 0.1 grams.
Are you wanting to dose that small of an amount on a regular basis? If so, it really is much easier to mix up your own liquid ferts and use some sort of dropper. I always prefer to measure the cap of whatever bottle I'll be using, and then mix up the ferts so that one capful is my target dose.
Any easy-to-use volumetric measurement of 0.1 gram will be rife with inconsistency.
I bought a scale on ebay for $20/shipped that weighs 0.1 grams up to almost 1.75 kg. Really great buy. I use it for fertilizer measurments and for homebrewing (not without a good wipe in between).
