I basically look at it like this..if you are finding the root system not drying out like you want it to and like multiple daily feeds until runoff..throw in some perlite or rice hulls on next transplant or next crop to dial in the right feed/dry down timings. But its not necessary. You can play with pot sizes as well. All dependent on strain..room condtions and dialage/mileage. Look at it this way...the big greenhouses that are replacing rockwool with coco coir for tomatoes and veggies just use big slabs of straight coco coir. They call them cocopeat grow bags but they are actually big thick slabs of straight high quality coco coir. Rio and PeleMix being popular brands for those growers. And those big hot house veggie growers have much thinner profit margins. Only employing equipment, techniques, and inputs that work period. If adding perlite affected the bottom line in a positive and dramatic way..believe me they would be making coco coir blends of all types for optimum production. They are looking for methods to water less..not more.
