What size bags of potting mix are those? I would really like to try that.
I believe it was the 25 quart size soil bag. I used Miracle Grow Potting Mix, so I didn’t need to fertilize at all. I wanted three small units versus one big one so I could grow various things, in sequence; lettuces, spinach and arugula. I grew some Red Orach, too, but it ended up not being appetizing to me. Fuzzy leaves? Nope! LOL!
I chose the bags, then went over to the storage area to make sure the bag fit neatly on the cover/lid of the clear storage bin. I chose a clear bin with a black lid, thinking the black might keep the soil warmer. Also, these were kept INSIDE my unheated greenhouse, so I’ve never used these grow boxes outside....but I will start greens extra early this coming Spring!
