it depends on the high you want. The more amber the more 'couch lock'. Mostly cloudy with a few Ambers is going to be a little more uplifting. My CP was harvested when mostly cloudy with about 20% amber. Its mellow creeper and is a good evening smoke and easy to sleep...if not conk out in the chair ;)
My Hindu is also mostly Indica and I harvested it with mostly cloudy, still a few clear and only a few Ambers. Its more 'up' and I cant toke it too close to bed time.
