I need to produce a specific amount, am I on the right track?

I would not waste so much money to get 1 ounce a month. I would not mess with any clone cab. you can literally do it in a tiny box for what you need. also no mother plants just clone the ones in flower to get your next ones ready. I would do soil as you can grow easily 6 ounces/3 months with a 600 in it. I would just put one clone in the flower room every 3 weeks so every 3 weeks you would harvest one plant and replace it with your next clone. no need to veg for hardly any time for the amount you desire. I would just put baby clones straight in there once rooted in a 1x1 box with a desk lamp. just my two cents. hydro maybe less watering though, not like a mini drip system would be hard or expensive.
