You can run a small heater or dehumidifier near your molds, which will help them dry. We let larger pieces sit until the wall-the solid layer next to the mold-is about 1/4" thick before pouring off the excess.
Pinholes can be caused by dirty molds. Older molds often leave pinholes, as the plaster has started to degrade with use. If you are using old molds, you may have to recast a master and recast the mold in new plaster. Most of the time a damp sponge or chamois will take care of them. If the top of the piece is plugged with semi-solid clay, you can poke it with a dowel or small sharp knife, then pour out the excess slip still inside the mold. Pieces with small gates (pour holes) often need this, especially if the rest of the piece is broader, like a tree mold will be.
The many variables of slip viscosity, temperature, mold dryness, air humidity, etc.,etc. mean you need lots of practice to gauge your cast pieces readiness to be pulled. Be prepared to experiment until you have a good idea of how the slip will act. You can reclaim your clay.
At this point you are in training to learn a new trade. You could be in school learning to be a nurse and have the same issues. With that in mind, is there a studio in town where you could work part time? The exposure to others working methods is valuable in itself, and if they can't pay cash, perhaps private lessons or free clay or some exchange could be worked out.
Also, decide for yourself what's really important to your family life and let the rest go. Home made dinner is nice, but it's time eating together that's more important to me. Adding layers of stress because society tells us to be "doing it all" will just drive you nuts. Kids really can amuse themselves. They will still thrive even if you take the time to clean. And a clean workspace equals better working habits, which means more money when you are trying to sell in quantity. Also, you can have them help with the chores-it builds character!
I use this as a selling point. I have a bit of schitck were I describe how beakers thousands of years old exist, and that the beaker they purchase today could be found by the archeologists of the future....it works pretty well, too!
This is like the question of how to have a "bikini body", which is answered by having a body, and wearing a bikini. Take the vessel you made, add dirt and seeds and you have a planter. Drill a few holes in the bottom if you really want to.
