I have a 6" in Veg and 8" in bloom running since February and so far no issue's. No idea on warranty?? I bought it for noise level as this was my number one priority.
Being new to indoor growing and coming up on my first harvest in about 2 weeks I thought I would share what I think I did wrong. Maybe others can add to the list from their experiences.
1) Yellow bag Miracle Grow. While this worked fantastic for me outdoors, not so much indoors in 2 gallon...
hotrodharleys advice is generally spot on. He must be having one of those days.
Be patient somebody with more knowledge will come along with more than a one liner. I have a few years to put under my belt still before I can give advice on indoor growing issue's. Sorry.
