Possibly the only farm (1900+), built it as I own BuyStarToolDroid

Obviously I was not aware that there was a second growlactus exploit that was patched silently so I ended up having all of those and there aren't any suppliers anymore. Average tools per 4 and a half day is ~130-150.
Initially bought them all for 3 to 4 each but now there is no fixed price anymore as I've even managed to find buyers for 10+ each.
