Couldn't agree more. Flourish tabs are head and shoulders above the rest. No nitrate spikes like DIY Osmocote tabs, they don't turn to dust in a day like most of the others and they last 3-6 months unlike some that need to be replaced monthly. Only reason they aren't universal is because they cost more than other kinds. I still use some DIY tabs but flourish is my mainstay.
