Thanks srh88 I didn't mean to get folks upset, I should have worded it different or not at all. I'm not good at using this phone. I'm old school and never was up on all the Tec stuff. My son tried to show me how to reply on here so I hope I get it right. Don't know how to take that post down. Anyway I was wondering about how to us grow cil and if it works ? Have you used it for outdoor in pots ? I live in northern Minnesota and grow time is limited. I look forward to your response . thanks again.
