Experiment Update 9-27
 

Well, I finally ran out of fertilizer, so I decided to commence Phase 2 of the experiment:

Epiweb vs PrimeAgra

The results from phase 1 are attached below. Overall, they both grew similar amounts, B slightly more than A (but A was a bigger plant to start out with). So it would seem that over the short term, the two fertilizer brands are essentially equal.

I presoaked the primeagra and the Epiweb in KLN (same bowl even), and the Epiweb plant has some gravel in the very bottom to give it some weight. A is in Primeagra, B is in Epiweb.
