  • I used to love this podcast

    This podcast used to give some pretty decent information when it was close to an hour long an episode. now that the show has been shortened down to less than a half hour there is no information. The show has become more of a sales platform for the different people being interviewed. It seems quite unfortunate for the general audience.

  • Too repetitive

    Claims to help growers grow-but it is more for new growers if they need a little help. Any seasoned grower wouldnt find anything new here
