You want amber in the curing process, but they should be harvested at 25percent amber. The plant continues to mature even while it's drying so if you wait too long a majority of the THC might lose potency by the time it's dry enough to smoke. Depending where you got your white widow it might be mostly sativa or mostly indica.The Cali version is closer to maui wowie and is mostly sativa , which won't help with insomnia, but there are Dutch versions heavier on the indie that might help. An easy way to tell is to check the fan leaves,5-7 broad leaves=indie,7-9 thin leaves=sativa, and hybrids will show something in between.
