This showdown is going to be in the same manner as my http://www.rollitup.org/grow-journals/358562-dyna-gro-vs-general-hydroponics.html journal in that it wont be a simultaneous grow-off, but rather a direct comparison of the base nutrient lines offered by DynaGro and Advanced Nutrients. Ill be comparing things like pH stability, salt build up, plant performance, plant health, nutrient concentration levels, and of course final yield. I chose Connoisseur because its probably the most expensive, over-hyped base nutrient on the market and as a veteran grower, Im in a much better position to put out the truth about the actual performance of this product than some beginner who just doesnt know any better. After 11 years in this hobby, Ive settled into the no-frills DynaGro brand which offers total and complete plant nutrition and isnt purposely split up into multiple products. Im not starting this journal because Im unhappy with my current nutrient brand, I just want to post some honest and bullshiz free info about ANs most prestigious base nutrient. Welcome to the no-hype zone . The strain well be working with is Serious Seeds AK47, a strain Ive grown many times before and am very familiar with. Using DynaGro, my yields for the past four grows have all been between 20 and 21.3 ounces (most recent harvest numbers are not in yet) so this shall be the benchmark for ANs Connoisseur. In regards to the final product, Ill also be looking for differences or similarities in potency, aroma and flavor, all of which will be 'tested' for in a blind comparison. Now AN fanboys are probably among the most annoying members in this community and there will probably be a few following along. There will be no arguing, personal attacks, or just plain old newb-grower ignorance in this thread, just the facts as I post them throughout this comparison. Unwanted and unwarranted posts will be reported. Let the competition begin . My setup is a DIY Ebb & Flow system with 6 inch rockwool cubes and a 600 watt HPS hortilux. I flood two to three times per day for 15 minutes with weekly res changes and a pH in the high 5's. These plants were vegged with DynaGro Grow and were also topped.
