Ive tried soil a couple times, then decided to try coco. My coco plants are about 3x the size of anything I’ve ever grown in soil. Everything I put into CoCo outgrows my soil plants. Maybe I just suck at soil lol!
To me - Soil requires guesswork. Coco is exact. Whatever you feed coco is what the plants get. In soil you have to plan ahead and things go much slower. In coco it’s ready, set, go. Just gotta keep the ppm’s and pH in check.
If you don’t want to tend to the plants daily, then soil could be the way to go. You can build a simple watering system for either type of medium. It’s hard to overwater coco.
I went with Canna brand nutrients and coco. You just mix equal parts of A+B. Easy. You’ll absolutely need to add some
CalMag with CoCo but don’t go overboard. I add about 3ml/gal of
calmag to bring the ppm’s up to about 200. I added some Silica, Rhizotonic, and Cannaboost as well during veg. You always add Silica first, then
calmag, then your base nutrients, then finally your additives. I wait a at least few minutes between adding different nutrients to let the solution settle out.
I’ve been feeding every 36-48 hours in bigass pots (for coco). 6.5ish gallon pots and they drink 2.5-3gallons every other day. That’s different than what most people do. Most people go with smaller pots and feed daily or multiple times a day. Never let the coco get completely dry. Never. I wait until the top layer gets dry, but if I scratch the surface it is nice and damp just below the surface. Most people never let the coco dry out at all with the daily/multiple times a day feeds. I plan on trying that technique next round with one plant.
You will use lots of nutrients with CoCo doing drain to waste, but it seems to be the best way to run it as opposed to a recirculating system. BUT people have had success with both... Just seems that most people (including me) drain to waste
If you have nutrient problems then flushing coco is super easy. I always water to like 30-40% runoff, drain to waste, and never flush.
I feed 6ml of A+B to clones and youngins. Then bump it up to 8ml/gal in veg. And I only use 9ml/gal so far in flowering. I added Cannaboost when the pistils started to really form and flowering was 100% in effect. It was about 12 days after the switch to 12/12. Going to add in a PK boost srpund week 5 of flowering.
