I dried the coco out because the plant had already fallen over, thinking i was overwatering and did this in a desperate attempt to help it... i later decided to water, and the next morning... that.
You need drainage. I like to use two solo cups in conjunction with one another. One full size as the outter container and one smaller 1/2 size cup inside of the full size cup. Poke holes in the bottom of the smaller cup for drainage. This allows the runoff to drain into the full size cup. I often find roots protruding through the bottom and growing into the run off of I let them go too long in the small cups.
The reasoning behind this is it allows you to use a container just big enough for what stage the plant is in. Once it becomes rootbound or rather just before you can transplant into a larger container. The upside is you introduce it into fresh growing medium that hasn’t been ruined by over/under fert, wrong ph, etc. So the plants will almost instantly take off and keep growing.
