Ugro coco v canna coco problem

[Bigbudbenny]

Hi I have been using ugro coco works great , I have tried using canna coco but I doesn't seem to dry out as fast as the ugro coco , I've used the same amount for both , the pot is still heavy after 2 weeks 😡 any ideas why this is ? I even took out some canna coco out of the pot cause I thought it was to much but still the same .

Have both pots got the same drainage holes in them?

I adjust the time between watering by adding perlite to my cana coco. With 1/3 perlite (by volume) I water 5 gallon fabric pots every 4th day with adult plants. I determined the time to water by weighing the pots as they dry out.
Many factors will effect time between watering, such as humidity, fan placement, temperature, type of pots, etc.
Folks tell me that when you change one thing, it changes everything in this hobby. I think they are right.
