I left of vaction and am back, ready to start dosing again. I went to measure out the ferts and the digital scale I bought (from ebay) says it needs to be recalibrated. I need 200g to recalibrate it. Anyone have any idea what I can use to recalibrate it without having to buy an expensive weight?

Just an idea.

You must find something small enough to fit on the scales and weigh 200 g exactly ,if you have access to another scales,weigh a couple of objects that total exactly 200 g then use it to recalibrate yours.

I think that if they had another scale it would be a problem.
Find something that has the weight listed on it and weigh

Thanks for all the help guys. I just talked to a friend of mine working in a lab and he said he'll take the scale into work tomorrow and recalibrate it using the weights he has there.

Cents can vary in weight up to 0.2g or more. You would get a very "rough" 200g from 80 cents.

Nickels weigh right at 5 grams. Old nickels 4.9 grams due to wear. Or you could weigh a small container and add enough water to get to 200 grams. Water weighs 1 gram per cc.
