Yay, my horseradish experiment worked

I just thought I'd try and slice a piece off a root I bought from the grocery and put it in a pot with the potting mix, after just over a week there are little green sprouts poking up

Needs to go in a big container, maybe a 10 gal. Also I need more space

Sweet Onion starts are taking up lots of room, and now I have some leek sprouts... The best spot I can think of is where my hydro setup is, it has the lights already hanging. Not much sun comes through our windows, but the leek sprouts did come up green in my bathroom, so they are getting sun through that window. Other thing taking up all the room is my Peppers, but they get Priority

and in 2 or 3 weeks I'll be starting my Tomatoes. Also we have frozen snow on the ground (if you don't know what I mean by frozen snow, we only usually get really wet snow, then it clears up and freezes the top layer into a hard shell.) So with that I can't work on the plot, also a question, we have a deer infestation, and we can't discharge a firearm in our area legally, what size fence do I need, 6 or 7 feet? so that means 8 or 9 foot posts? Anyways, maybe I can setup a spot in the garage with a workbench and some fluoros for some added seed starting space without having to scrap my hydro projects which I don't want to do, they are all flowering/fruiting... Which will give me a chance for some pure seed.
Thats all for now.
