If the gains were entirely exclusive to this product alone you would have my ear. A experienced grower in this thread has used the product and stated he is getting better yields with products that cost half as much. Couple that with the fact that so many expensive products in the past have similarly been ripped apart and then done cheaper, the myth busters would be asking why they are still here.
Side by sides are great, hope more people report on this product. But only from the mentality of what products performed similarly for cheaper, that is where people who run those tests with that goal do us all a service. The rest might as well work for AN.
Growers doing comparison grows often test... not perfectly scientifically. Which is fine, just, it makes me want to see results from multiple people. We have one grower in this thread that said that, and we have one grower on youtube who showed evidence of it that was pretty substantial. So more side by sides with correct dosage in controlled side by sides are required to stop evidence from just being anecdotal. Also reporting what medium and other stuff you were using during the grow, since there is a white paper on some enzymes being stymied by fulvic acid, etc that wasn't taken into account.
Also, it's great that people will want to compare this to another cheaper product! Stopping companies from taking advantage of new/rich/lazy growers is commendable. I really don't want to pay $200 for 6 months of product that I could buy for $20. (dry nutrients come to mind) I just have found that on these forums people show up to shit on new things, offering nothing in return. What I would love to see is more people being interesting in growing (punny!) as growers, testing new methods/products as close to scientific as possible and sharing (fully) the results with the community so they can make a consensus. Granted, I'm new, but this has been my experience thus far.
