Every day I bring you an item on Amazon that I personally use or has been purchased by many members of the audience and I have researched enough to recommend.
Today’s TSP Item of the day is the Greater Goods Digital Pocket Scale which I both own and love. I have verified its repeated accuracy and done so by measuring the weight of bullet in grains from 35 grains up to 405 grains. It has shown itself to be within one grain accuracy for all the tests. Honestly it is more likely that some of the bullets are off by a grain then the scale is. Precision reloaders often cull bullets by doing this to all of them.
This is a piece of kit many of you need if you want to do well with hydroponics that we discussed recently. When mixing a product like Masterblend by the gallon your weaker solution is going to be two parts at 2 grams to the gallon and one part at 1 gram to the gallon. You need a scale that measures accurately at a very small weight to be on the money.
That said you should be checking your solution with an EC meter anyway so if you are a little light you just add a bit, if a little heavy dilute with a bit of water. And I don’t strive for perfect anyway. Rather than EC I use the PPM reading for most of my work, it is just as good. I am looking for a PPM of about 550 based on my starting PPM with rain water of about 2. If it says 520, I am fine, if it says 600, fine, get it? Unless it is way out of wack I just roll.
UPDATE – Having done hydro now for over 2 years, I no longer follow my own advice in the paragraph above. I simply mix the 2-2-1 formula for MasterBlend and go on with my life. I am sure if I was doing a small commercial operation or a very large grow system doing peppers and tomatoes etc. I would take every step to optimize. However, on my homestead I try to optimize via elimination of things I don’t have to do. I grow 95% herbs and leaf crops with hydro, they don’t seem to care so I don’t either. Do with that info as you will. The truth though is I don’t even know where my EC meter is now, I think I gave it away.
What I will add though is I am so confident in the Greater Goods Digital Pocket Scale that I would use it for pocket reloading of ammo too. Now I would always check with a known weight for calibration first, two is even better say a light and a heavier one.
So if you want to take your hydroponics to the next level get either one of these. If you know you want to use it for reloading too, I personally have confidence in the Greater Goods Digital Pocket Scale but again always check with a calibration weight.

P.S. – I would not use this scale or anything like it as a primary reloading scale, I see it more as a shirt pocket scale where you stay say 10% under maximum at all times, for like shooting bench reloading with something like a Lee Loader, just to be clear. Also if you really want to test out a scale you can get a gram calibration weight set, but I think for this level of use it may be over kill, especially if you have access to pellets or bullets of known weight in grains to use instead.
