Night Temp's

RwhideSmith · March 18, 2016

For those of you who take your transplants outside during the day, what is the minimum low temperature you might leave them outside overnight?

BigVanVader · March 18, 2016

My limit is about 40 degrees.

IF the forecast was accurate I'd go for 40F but considering they're wrong about half the time and it gets as much as 5 degrees cooler I go with 45F.

You have to harden them off first.
When I am hardening off I put my plants either inside cold frame or under mini hoop.
Once done that occasional mid 30s should be ok, if it is not windy. But 40F is pretty safe bet.
I have had many night lows dropping down to 37.
I would worry if there is a "frost warning".

40 degrees is my limit. A few years ago, temps were forecast to be mid 30's. I had mine in a little hoop house. Lows that morning went to 30 or a little lower. I also account for my micro climate which always seems to be cooler than the forecast.

I dont depend on the weather people for my information.
What I have done is compared what a near by weather gathering station has to my house.
I also have a wireless Rainbird rain sensor that also detects temperature that I can set it from 33 to 41 degrees F.
By looking at the receiver in the garage or on my computer I can tell if it is about to freeze or not.

For me, it depends. If the plants are planted in-ground they can take cooler temperatures than if they are still in the potted up stage.

It got to 33 last night here and is supposed to go down to 29 tonight, so I cove4red my baskets and brought the smaller trays inside the brick porch and covered them. Will tonight, too.

Because weather can be off several degrees, when it is close, especially at this time of year, I play it safe for tender babies. Ot6herwise a miss call on my part can wipe them out.

Spring is changeable here, and fast, too.

So true.
Not much warmer here. I covered for protection because as Worth said, dont fully trust weather reports. At 7AM today the thermometer outside said 37F, under the tarp the air temp read 49. Also savgs all my plants from the hail we had late last week.

Put a light any light in there if you have one.
