Every one to two weeks you should see a difference in color

If I post a pic of the color it might actually look lighter or darker than the actual thing. But there's a way to find out with homemade tools.
First get a straw
Preferably red but white works too
Bend the tip
Slowly lower the straw vertically in a 90degree angle until you can't see the bent tip. Measure the distance
Around 1.5"-2" is 3-4weeks from harvest
Around an 1" is 1-2 weeks from harvest (can be harvested at this stage but it isn't dense enough for what's considered a "full dose"
Harvesting should be 1cm depth or less
Here's a pic of a culture at harvesting state
