TBH, I think you over-complicate this. 1. Dry-weight scales are very common in produce/stores and extremely common in EU stores (I'm in Russia right now and it's de-facto the standard for most every store) 2. Get a few scales cause you can use them for all produce year around, and they easily earn their keep, and the upkeep is cheap 3. Pre-pick pumpkins under a certain threshold and sell at flat prices; this creates two sale levels: one for those who want a big pumpkin to mess with, one for those who just want a pumpkin to carve. The latter doesn't need to be heavily regulated, your workers can just eye-ball it and given the margins around Halloween you won't really lose out (probably such "eye-balling" will benefit the farm, not the consumer) The technical solution here might eventually be more accurate, but it doesn't really benefit anyone. The conditions to make the camera detection work are wonky and you probably end up wasting more time making sane conditions for detection than you do just setting some limits. Similarly, don't forget that too much tech, and it actually might __discourage__ people as they see the farm as non-authentic. The aesthetic of an organic "real" farm doesn't include a lot of high-tech in many people's minds, and you risk offending the wisdom of the masses by being "too technological". Granted, there's absolutely no difference in the end result, but consumers certainly thing differently about it (there's a reason a lot of people still prefer a human cashier to the touch-screen terminals at fast food restaurants, and it's not efficiency, that's for sure)
