I have not used them before, but I do like to try new things and part of my reason for my grow journals is not to show how well (or poorly ) I grow. My reasoning is to help people learn along with me. If I was just going to do what worked, I'd be growing in earthboxes. Next winter I'm going to do a perpetual grow for about 6 months.Recharge is good stuff, but I've never used the grow dots. I felt, with a simple formula like Jack's in peat, I'd have more control over excesses or deficiencies than with dots. Recharge works so well, I might rethink my position. I'll be watching to see your results with them.
But yeah, check in and hopefully we can see how these grow dots work. I just ordered a few small fans and a couple of exhale bags. As well as my 2nd light for the 2x4.
