Just looking for different experiences from growers who use coco as media.pros, cons etc, also please elaborate, thanks, peace!

Nutes need to be lower in K than N.
Ca needs to be around 5%
Mg needs to be around 2%
Look out for Ca and Mg def during flowering as coco can hold onto both of these as time progresses.
Watch out for K tox if using high K nutes which will also slow uptake of Mg and Fe.
PH between 5.5-6.5 and the coco will buffer pretty well.
Always achieve at least 20% runoff.
Never use plain water as it messes around with rootzone EC to much.
Coco performs best when the rootzone is kept around 1.3EC. To test this use the 1:1.5 extraction method.
Choose a good quality coco that's buffered with calcium nitrate to around 1.5EC.
Feed with every watering and if you over do the nutes don't use plain water just back off a couple of points on the EC.
Never allow the coco to dry out excessively as this can cause salt build up and can change the rootzone pH to an unstable range.
That's about all I can think of right now.

Jondamon had some really good info in his post
I'll do 16 - 1 gallon mesh bottom pots per 4X4 tray under a 1000w. Vegged to about 10" before flip. Run to waste, fed via basket drip stakes. 3-4 feed cycles per light cycle. Each drip (not really drip) cycle is long enough to achieve runoff. Fucking rocks. But lots of plants, if you have lots of lights
I'll do anywhere from 4-9 plants(with 6 being what I usually do these days)in 5 to 7 gallon pots, per 4X4 under a 1000w. I treat these ALMOST as I would with dirt. The main difference, besides the slightly different nutrient needs(what jondamon said, and what I said in that other post), is NOT to let it dry out as much as you would with dirt. In peak flower, I water every other day. It rocks also, but much more veg needed of course
I use Big City Hydro mix lately, just to save on labor
You still want to rinse your coco, i don't care what brand. I transplant, then I rinse with water + 1/2 tsp per gal of calmag, ph'd to 6.0. I rinse till runoff is clear, and ppm is the same as what went in. Then feed, and walk away.
