But if you have plants, they will need to be watered and it will only take one accident to dump a whole watering can! Or simply to overflow a pot. I always like to plan for fate to get me, and then be pleasantly surprised when it doesn't!

We were just discussing that!  I have a rubber-backed carpet that I'll put under the pots to catch slight overflow issues... i am hoping that as long as we allow for evaporation,  it'll be ok... the air is quite dry in winter!

Did you use nails or screws to hold the floorboards down? Maybe leave some boards unfastened in spots for checking and potentially sopping up accumulated moisture?

Ah! That's a good point... we are using deck screws to secure the floorboards, but leaving at least one loose board is a good idea! On the up side, if it's just condensation on the walls, that will land in the channels at the bottom of the walls, and should not end up in the straw.

I'm hoping the tarp underneath with help with that; it is about 24" oversized on each side so it's tucked up and over the edges; it's not the low spot in the yard, so it should not have standing water under it; just rain runoff until we get snow.  If we start to smell it getting funky, we will probably retire it for the season and try something new in the spring (we are using things I already had on hand for the most part, so the straw bale was already here. As much as it would be fantastic to be able to use it all winter, it's definitely an experiment this year, so I'm not going to be devastated if things don't work out, otherwise the straw will get removed in the spring either way!

That is a nice set up that you have.

thanks! I'm putting a low (12") raised bed on the south side (planting garlic there) so I'll have the soil in that for insulation, but additional bales on the the outside is a good plan!  (If I put them inside, I'd have no room for plants lol!)

Well the gent managed to scrounge up some wood,  so I'm getting a floor after all!

That's an interesting idea, but unfortunately i have 4 large dogs who would DEFINITELY shred anything like that outside the greenhouse! Also, since the greenhouse is so small, there is a 100% chance that the ground will be very very frozen by December. Once we are in a more permanent location,  i have big plans to dig down and insulate a perimeter (of a bigger greenhouse) so we can use the ground as a thermal mass, but i can't see that there will be anything but heat loss in our current setup.

(thank you for the idea though, filing it away in my future plans folder!)

I need some help... we have a tiny polycarbonate greenhouse (6x8') from a kit and I'm planning to try to winterize it to extend my season on some cold weather crops (everything in pots and grow bags), and protect some other plants for the winter. I'm in zone 4a, so winter is coming awfully soon  (we have a high of 9c expected today!)

I have clear bubblewrap to insulate the south side, and reflective bubblewrap for the rest. I have a string of incandescent outdoor lights to add a bit of heat when needed, and a water barrel for thermal mass. (as soon as i figure out how to get it in as its JUST wider than the doorway). I have an actual space heater as a backup to all of this, plugged into a temperature sensor, but don't plan to run it except in dire emergencies.

This place is not a permanent location for us...probably one or 2 more years at most.

Now for the crux... it has no flooring as of yet, and it has a low spot in the middle. I don't have the capacity at the moment to build a proper floor this fall, and anything i do needs to be removable. What i have right now is a couple of (black) outdoor carpets for weed suppression. There are also gaps along the bottom of the walls (we levelled and supported the corners,  built a wood frame, etc.)

I have some metal meshing to keep rodents out of the gaps, but i need to figure out cheap and easy ways to stop the air flow under there, and possibly insulate the ground a bit.

Any suggestions? TIA.

My sister and BIL are bee farmers, and last year they had a very special batch of honey where the bees were gathering in an area with a lot of ants and aphids,  so the honey was heavily flavoured by honeydew. They gifted us a tub of this honey snd my goodness it is incredible!

I don't even know, but the area doesn't smell like it did 30 years ago (and that's a good thing!)

The amaranth is quite dramatic isn't it? That's  "Love Lies Bleeding" and "Hot Biscuit" behind it. They were definitely more than I expected! Nice to have something exceed expectations,  as I also had some colour disappointment... the nasturtiums that are bright red were supposed to be "black velvet" (while I wasn't expecting a true black, I wasn't looking for BRIGHT red either!)
