Just food for thought, but these monetary considerations, ie, cost per ounce, were the main reason that I went to a reusable organic soil model. Outside of the electricity costs for my now super efficient COB lights (that I will run at 90w total in early veg) I have no real expenses for this current grow. I do not use nutes, but I will buy my water at the grocery store at .89c per gallon. It is all about how to be a miser for me, or why would I do this if it would be cheaper and easier to just go to the dispensary and pay their prices?
Also, a well managed soil grow can give you oftentimes throughout the grow, 2-3 days in a row where you really don't need to do anything with the plants except watch them grow. This is why coco and many of the other hands on every day methods just wont work for me... I have a life and many times I need to jet out for a day or two during a grow.
Kudos on being patient and waiting for your plants to get done... despite them taking their time about it. You are a talented grower, and I look forward to you coming back when circumstances sort themselves.
