I wouldn't call them clear!
Well it's all down to genetics and what you like best. I recommend taking some a little before you think it would be ready, most of it when you think it's ready, and then save a little bit more to grab the next week or two. That way you can directly compare them and if you grow out that strain in the future you have an idea when to harvest that you will most prefer. I don't think there is any set, hard rules because it's up to the preference of the smoker. Some people want body high some people want mind high and some people just want the medicinal value with no high.I don't see seeds and I'm happy about that. My concern is that while I'm waiting for the cloudy ones to appear, more and more of the amber ones will pop up and I don't really want that since the high will be a "couch-lock / sleepy" one - indica
