They're certainly rootbound somewhat.. but its nothing more than they have been for the last couple of weeks of their growing cycle, its just been since the heat I think...

Other than perhaps digging them into the ground next time around (6 months or so) as these are pretty much the largest pots you can easily buy here.

Yes, its a coco looking stuff.. coconut husk or something I think its suppose to be? its good for drainage etc.

I water for 4 minutes 3 times a day and for another 2-3 minutes in the middle of the night... there is always moisture an inch or so under the surface.

we've had a couple of days in the 100's but nothing prolonged.. it would get warmer than that in the greenhouse given how it works, but the fans and the water keeps it going.

I have some in smaller pots outside that i pretty much neglect other than giving it water every now and then and they're going fine.. not showing any signs like these ones are.
