Brix Meter (refractometer)
Has anyone used a brix meter as part of their grow?
Also known a refractometer (or reflectometer?) , a brix meter measures the sugar content of plant tissue. It has a prism on one end and an eyepiece on the other. When a drop of sap or juice is viewed through the meter a reading is given that indicates dissolved solids in the plant's system. This can give a much better picture of plant health than guesswork based on how the foliage looks etc. as well as alerting the grower to deficiencies or toxicities in the soil/medium/water.
I think they can also be used to assess ripeness, as I originally heard of them in the context of wine-making (although perhaps sugar levels can't be used to gauge ripeness in Cannabis as it is in grape vines.)
The meter isn't terribly expensive, around $100 for a Milwaukee.
Has anyone had any experience with these?

yeah brix meters are useful when making sure u plants are healthy
a brix reading of 12 means plants are healthy i think it is ill look it up and get back to you on that one
a good investment but not very neccesary a ph meter and a ec/ppm meter deffinately more important but if you got the money get it =)
