Did a great job and did what it was supposed to do :fire:
Highly recommend, especially if your using autopots.
Best nutrients used to date, high-quality and great results!!!
This is my second grow using these and both times I've been very happy with the quality and the plants have always responded well.

Greening my cheeba up nicely after some noob gardening mistakes. Locked her out of nutrients at the 6th week of veg and it took a couple of weeks to get the learning curve done. With the medium drying out properly between waterings, the pH in good range for uptake, allowing 25% runoff, and some added Pro-Cal... things are getting back on track and I'm going to flip her to flower. I'll continue to add some Pro-Cal throughout flower.
