i use rainwater from a DIY cistern for my 5 gal DWC. recently i've noticed that even with filtering thru cheesecloth the water is urine color from pollen. when i looked up the chemical composition of pollen and found that its approx 60%lipoprotein to include all the amino acids, 30%carbohydrates of which lactose was predominate, and 2%K. the rest was fiber. i use subcultureB in my system so the microbes should be able to convert this into food. i was looking at the ingredients in advanced nutrients Big bud bloom booster and they were almost identical to pollen. any thoughts on using unfiltered pollen?
