thanks man :) both have the same volume of substrate, the pots are however different in shape so it does throw the experiment off but the cream pot with soil in it has a water reservois on the bottom 4 inches of the pot so thats why it looks considerably larger but i filled it with one load of soil from the black pot which the coco PE is in so they had near on the same volume

Awesome man ill check them out :)

Good luck with the grow ;)

thanks @bobo420!
