@Caanan18 - just search on amazon for tropf blumat kit and it should be about $36 before shipping right now. (I can't remember if it's a 5 or 6 carrot kit).
Another thing you might want to search for is a usb microscope, there are some alright ones for under $25. I used one last time and threw away my little handheld 60x microscope. All you do it cut a small part of a leaf off near the top of one of your major buds and look at it under there with your computer.
Once you have harvested a few times, you would be able to tell when they are ripe without a scope, like Dr. Who was getting at.
Hope you get feeling better, but unfortunately your plants won't care
