I remember my first! I read all the articles. I found the GWE website. I sweated all the details. And I was scared! I hovered over my girls for 5 months, 3 weeks, 2 days, 6 minutes, and 37 seconds.
Almost 2 years later, it has become so routine and so easy. I don't have to think twice about what I'm doing. So I'm always working on improvements and trying different things. (My new thing is coco coir.) If I have issues, questions, concerns, thoughts...I come to this forum. Occasionally I add my 2 cents to posts.
Eventually, it all pays off and you will relax a bit, too.
