I wanted to dig up this thread the other day and i forgot too
i notice that loose cubes dry out more fully as opposed to a lot of the other media i have played with.
I have made a bunch of tubes of gutter guard and filled them with all manner of medium for different plants. For my bulbos that climb i used straight cubes. I have others with mixes of leca and cubes, coir and cubes, leca and coal and coir and i have a few with perlite too.
one day i was watering and i noticed the cubes looked really dry so i checked a bunch and all the ones with the cubes visible appeared very dry. it had been a few days and i wanted more than just looking at them so i watered and weighed 10 tubes. weighed them again the next day and so on for a week.
THe pure cubes gained the most weight (no surprise as they hold the most water) and lost the most weight. so i was curious if they were still moist at all and opened on of the tubes and the cubes were super dry, like from the bag dry.
I have always insisted that leca never gets fully dry in South Florida but i think the grocubes open structure and packing them loose exposes more surface area and allows for some really dry medium if you arent witchful.
i added some punky old pieces of broken basket wood into those mounts to see if it will act as a reservior of sorts.
just some anecdotal gro cube observations
