In the greenhouse at night?

[PlantNurse15]

Hey all,

My greenhouse is finished which is very exciting but I am wondering if I can leave my flower seedlings in there at night? The lowest it is going to get at night in the next week is 33 degrees Fahrenheit.

Thank you!

Get some water containers in there to add thermal mass (or run a small space heater if it gets critical) and you should be fine. Congratulations on finishing it up in time for the season!

Thank you PhilaCardener!

yes, thermal mass, you can also use rocks or bricks, or barrels of water.

That's pretty cold 33 F ~ yeh containers will work if there is direct sun ```

Depending on the day time temps you could possibly set new starts out there, but I wouldn't until the temp, in the greenhouse stays above 45 at night.

I'm with this advice. I'd be scared but I'm also risk adverse

Exactly!! Horse breeders with very expensive stock heat their barns in the winter to...you guessed it, 45 degrees, constant. I have my tomato seedlings in a leaky 10 gallon fish tank, sitting on the ledge on my windowed but unheated east facing front porch. I have a heat mat underneath them. I have been unplugging and replugging it all week. This really is work, but the payoff is you haven't brought in any insects or mold from plants sold at box stores, which is where I am certain I picked up squash vine borers and squash bugs.
