  1. C D Jones

    I’m a first time grower and used this medium to start my vegetable seedlings. I’ve had such great success with this product as it seems so easy for the plugs to find their way into it and flourish. I’ve checked on the root structure and it’s beyond compelling given I have a learning curve to adjust to in regards to watering and feeding. It was just easy to watch the plants take off after transplanting. It gave my first round almost 100% success when I transferred them into outdoor plot. Clearly a good beginning makes for a longevity in this crazy hot Oklahoma weather. I’ll be excited to try it again for my next round when the time comes.
