Were you hoping to extend your growing season with water barrels?
They work well all summer long to take the chill off.
However , be forewarned they work completely backwards, when you ask them to work in the spring or fall.
That same water mass that holds heat, also will go cold and steal heat... Will take all day on a sunny spring day for them to absorb heat.That heat "might " be enough to keep your plants warm.
On a cloudy day they stay cool and steal heat! Plants go cold., nothing thrives, if they survive at all.
They also take up a huge area...
That same area "could" have a rocket mass heater! Nice long warm mass to set your starts on. Will definitely extend your season right into winter if you wish.
Come check out the RMH forum here at Permies. We even have a section on rmh's in greenhouses.
I keep a plastic greenhouse warm all winter in northern Montana with a RMH. No fire all night long... no creosote ever, clean ash out once a year...Less than 5 cords of wood to do this.
Even if you do not desire one in your greenhouse, it is just good information to have in your head.
You never know... you might want one in the future in your home.

As I said, I have been married twice before, so when I met Katie, and things got serious between us, I was worried as she had two children, and I did not want to enter and exit their lives and cause irreversible harm. So I prayed, because I am a believer, and it was like he answered clear as a bell in a quiet voice, "And who did you say you were going to marry when you were a kid?"
When I was young, and played with my toy tractors and trucks, I always pretended I had a Katie for a wife. Then one day I heard a sermon on prating specifically, so I prayed my wife would be a Katie, that is how I would know.
But then I married a Tina and a Patty and wondered why it did not work out? Katie though, she is special, and my best friend. It is also why I use her name Katie a lot instead of wife. Her name means so much to me.

This is where the logs are laid vertically instead of horizontally because it allows a camp to be made with smaller logs, and shorter logs. I know it does not have the traditional look, but Maine Loggers developed this because the logging companies did not want to use good trees to make logging camps for the loggers, but instead wanted those good trees to go down to the mills as logs, and instead use smaller, shorter trees to build cabins to live in as they cut wood.
