Moving Day I Think?

[big rockpile]

I moved some plants inside the house and put a 750W Grow Light over them they kind of like it.

Well last night the Grow Light fell because I don't have enough support.

So I'm thinking move them back to the Greenhouse. I have Electric Heater going now keeping the Greenhouse in the 50's F at night. Plus have Grow Lights for a few hours in the evening.

Wednesday going to put a Propane Heater in there.

Will it hurt to move them to the Greenhouse where it is cooler at night but they will get better Light? I know it is a trade off.

Got some Ferns in the Greenhouse under the bench so they have some shade but I'm thinking just move them into the house.

They should be ok in the heated greenhouse but here in 6b it can get a little pricey even at 50 degrees.

Yes it last year ran $500 in Electric for House, Apartment and Greenhouse a month.

We are changing more to Propane but still have two Cabins that are Electric.

Humidity can become a thing burning gas, I put a copper 'chimney' pipe on my greenhouse heater, all the heat stays in the house, without the water. Have to be careful not to have the flame under the pipe. The water condenses, runs down and puts the flame out otherwise.

I'm going to leave my Electric Heater on just in case.

From my aquaponics days I remember something about propane heat producing some sort of beneficial gas for the greenhouse.

something about propane heat producing some sort of beneficial gas

CO2, carbon dioxide? Used in photosynthesis. Propane is a three atom carbon chain with eight hydrogens off the the sides and at the ends, when it burns the hydrogen is oxidised to water and the carbon to carbon dioxide. Okay if there are no impurities.

Yeah that's it. Thanks. So not only is propane heat cheaper than electric there is this other benefit in the greenhouse.

Yes burning hydrocarbons with an adequate amount of oxygen gives carbon dioxide and water. However the heater is on mainly at night and in cold conditions; plants don't do much photosynthesis either at night or in cold low light winter conditions. As soon as your heater goes off the carbon dioxide level drops back towards normal.

"Adequate" is the key word, might well be worth putting a carbon monoxide detector in there just in case, it's a nasty form of poisoning, it binds with the haemoglobin in the blood. You go bright red and there is dizziness and confusion, I know some of us are like that anyway, but then it is vomiting and death.
Carbon monoxide detectors are not too dear £15 - £30 and run on batteries so you can put them anywhere, any sort of gas burning appliance or wood stove it's worth having one around, I think a legal requirement in the UK

Ok listening to a Greenhose Keeper that has used the same Heater I'm using for the last 20 years.

Brought up valid points. What if electricity is out for too long? The propane Heater heats and puts off CO2 which the plants like.

He did bring up vapor which the plants also like to a point but set the Exhaust Fan to come on when the Greenhouse is heating by the sun but if it is cloudy for few days and it gets too bad manually turn the Exhaust Fan on.

Oliver Buckle I do hear your word but let me try.

Oh have used CO2 to make plants do better. You can buy cannisters of it just for plants. And yes I know it will kill you. Right now I'm warming by a Ventless Propane Fireplace and yes I put up a CO2 meter and in two years it hasn't went off.

CO2 shouldn't be a problem in a greenhouse. I've never seen one that is sealed well enough for that to be a problem. BTW indoor ventless propane heaters come in 2 different types, blue and orange flame. Make sure you get the best one for you.

 

[Oliver Buckle]

It's not CO2, the dioxide, that could suffocate you but it would need a heck of a lot. It's CO the monoxide you really need to be careful of, it only needs a bit of that in the air, but so long as it is burning properly it shouldn't be a problem.

I've use both and haven't had a problem.

I bought one that burns Orange for the Greenhouse but my son was needing a Heater so it went there I ordered another.

Right now I'm using an Electric Heater and is doing fine but it's only 19F outside. If it gets colder I'll have to do something.

Onions are coming up but their on a Heat Mat.
