[GSAS-Member] Aquatic Plant Stuff & Gregg Watson Ferts

Susan:

I am glad to hear that you are taking the next step to explosive plant growth.

I would recommend reading this longish article by Tom Barr on the estimative 
index to start:
http://www.barrreport.com/estimative-index/62-estimative-index-dosing-no-need-test-kits.html

After you get the general idea we can discuss variations, (PMDD <"poor man's 
Dupla drops">, dry dosing vs home made solutions etc.)

We can also discuss local and national sources.

Enjoy!
-Paul
