i work for the biggest hydro retailer in boulder colorado and i can tell you right now that the only people in my shop using AN are the newbiest of the newbz.
Its one of our slowest moving lines with the highest markup and we more commonly have customers that are buying the one liter sized bottles as opposed to gallon/2.5 gallon and bigger.
This tells me that the only people who are wiling to run their nutrients, are just starting- hobbiest kind of growers.
carboload might have been their one stand out product that people liked to add to their nutrients regimens and also bud candy sells decent well.
carboload was recently reformulated to add another 45% water. these bottles use to feel thick. Almost like a molasses but now its just like any other watered down BS
good luck guys!! Meow
I think it should tell you that your prices cannot compete with what people can get online, shipped to their door for free, under MSRP. It's not like every gardener comes to the retail store.
I have several customers that have been buying Sensi Bloom in the 10L size like clockwork for a few years. Big Bud Dry does well too. And their pH down seems to find its way into gardens.
