I think @Nicky might have some input about that.
I was afraid of coco for the same reason but I’ve seen what folks do around here and how long they’re away from home. My longest stunts are usually 48-72 hrs so it’s nothing in the long run.
Auto pots and automatic watering systems in general are incredible for coco.
Think I could grow outdoors just in one of those plastic totes if I drilled a lot of drainage holes? It would be easiet to slide a tote than haul a bag if I have to move things. Just wondering if it would be feasible.
Dont know why not.
Keep in mind if the container has holes on the bottom the roots will grow through and into the dirt if its sitting on the ground. Same with a fabric pot on the dirt. Roots grow right through and anchor the plant in place.
you could probably put some type of material in the bottom of the tub that would prohibit root growth out of the bottom. Autopots have that copper sprayed surface to prevent root growth out of the bottom. I don’t know, but I would hazard to guess that the black material you buy at the big box stores would do the same thing.
Update:
So after watering daily as recommended i feel like they start to look healthier.
The new growth is still a bit yellow but it becomes more green day by day.
Here are some pictures :
That’s totally normal. The new stuff doesn’t have the chlorophyll totally developed so as they grow they deepen and look more like the rest of the plant. That’s why lots of seedlings look so sad and weak when they first sprout. No need for chlorophyll underground. 
Update:
Hello for those who care, i just switched to 12/12 cycle a few days ago.
Before triggering i repottet them into 11L pots and i did some defoliation + removing the growth on the lower 1/3 of the plants.
When i repottet them i noticed that some of my roots were brownish, i never let them sit in water and my media is mainly coco and perlite so i dont really know what else i can do to prevent root rot.
This is how they look now:
Happy growing🙂
Might not have been root rot. Probably just stained from the nutrients. They look great 
True that. N will raise PH. Leave out worm castings in that mix and use peat, coco and perlite for great success. IMO. Happy garden growing!
Oh ok thats really nice to hear, i did not know that could happen…
Thank you 
Great looking garden!
They do look quite healthy. Per previous comments, adding organic medium to a coco grow does complicate things… and defeats the purpose of using a medium like coco. I use coco and perlite only, buffered, of course, and then strictly control my watering ph and nutes. You can have a healthy microbial presence simply by adding inoculant to your pots before transplant and watering in compost/worm teas (with appropriate food like humic acid, molasses, etc) regularly. (Naturally, you cannot use tap water that hasn’t sat for a day or two, as the chlorine and other gases will be detrimental to the microbes.) Mycorrhizae actually do well in coco, as they get plenty of oxygen and cellulose. I have had great success with an auto water, 10-20% runoff. I hand water the teas, of course. There is also some debate over whether one needs to worry about ph as much if the mycorrhizal colonies are thriving in an organic medium, since they create optimal conditions for nutrient uptake (within the rhizosphere). When I did pure organic with tea brews going in everyday, I didn’t touch a ph meter, and my plants thrived. Folic acid can help with that as well. I’m not going to state this as anything but conjecture, but having the castings in there may be changing the dynamics of cation exchange and allowing for uptake at a higher ph than coco alone would allow for. Anyone have any thoughts on that?
Root rot not likely in coco as long as they aren’t sitting in runoff. Like mattybear said. Likely stained
