Hey Atomramble, Thanks so much!! <3 I understand finding a suitable location can be difficult, I don't have very much light inside the house for plants, I do have a porch that gets enough sun to be sufficient for most herbs and even some tomato and pepper plants, its only 4 by 5 feet. If you have any space outside to use, I would watch the location to see how much the sun hits it and then decide if its enough for plants! 8-10 hours is great, i think they could manage with 6 if needed. Jar capacity depends on the jar, if i don't have enough space on my shelves for more jars, or sometimes if the jar is too wide I might need more than one plant to help hold each other up. I had some pretty small lemon balm cuttings i put 4 in each jar! You will have to refill the jar with water more often though, but they are only in the jar for a week or two and then can be transplanted so its no biggy! <3
