I might try switching from perlite/verc to Coco with the bottom of mixed with Hydroton hempy & see what bubbles with that endeavor...
I kind of did that. I ran a few experiments. At first I grew them all in 100% perlite, then perlite/verm, then perlite/shredded rapid rooters, and finally coco/perlite.
The best mix was coco/perlite without a doubt. The reason being: All the other mixes didn't provide enough support, requiring me to tie the girls up to keep them from falling over. The other mixes also wasted too much solution, but the number one reason I like coco/perlite is because it promoted superior side branching of the roots. All the other mixes tend to produce one big winding taproot with little branching out. The coco roots were healthier.
Alas, I'm hanging up my 100%-perlite-boots. Originally I wanted to reuse the perlite, but well.. its such a mess. I want to figure out a light soilless organic media for next time. Trying to avoid soil and peat since they are no bueno for the environment. Can you use bat guano and stuff like that with coco?
I'm using 3 parts Perlite to 1 part Vermiculite HempyJust keep the coco moist. Heft the cups and feel the weight after watering. Try to keep them from drying out. Situation dependent on watering. Size of plant, temp/humidity, airflow etc. will all play a role in how much to water.
I water once a day usually, but as for seedlings, they don't use as much water, and it is better to not waterlog the coco so they can develop a better root structure. Let them search for the water, but don't get the coco too dry.
