warm up your greenhouse  -  twin wall polycarbonate
Burning furniture to keep the greenhouse warm can be considered quite extreme.
But when last year's big freeze coincided with the oil crisis, expert herb grower Jekka McVicar had to sacrifice all her houses and ovens for heating during Christmas, to keep her precious inventory alive in the greenhouse until the tanker can be in Gloucester
As the greenhouse plants were prepared for my Chelsea garden, I am very grateful.
The long cold winter of the past three years means keeping the greenhouse and even frost
Free is a big cost.
Now it's like we want to jump
It makes sense to start the garden and let many early plants grow, using savvy techniques to save fuel.
For those in the greenhouse, an ideal place is to lean against the south wall, where it can enjoy radiant heat at night. The east-
The western line will also maximize the amount of sunshine.
If, like me, you're stuck in an old greenhouse in the North
Don't despair in the face of the wall.
Paint the exterior walls white to reflect the extra light and benefit from the radiant heat.
My tomatoes and cucumbers look much better than you think.
I like Douban very much! The old-
The style pit conservatory, which sinks about 70 cm to one metre underground, clearly does save heating.
One of my savvy builder clients built one on their own and I copied his second greenhouse.
You can dig the speed of the area with a mini excavator and the fact that you can escape with concrete blocks (
Relative to brick/Stone)
For the surrounding walls that are not visible to the outside, this may mean that the difference in the cost of the building is negligible.
Even if you don't sink it, build it on the low brick or stone side, which saves heat.
The wood frame reduces the heat loss compared to the metal.
If you want to reduce the operating cost of an existing greenhouse, it makes sense how to use the greenhouse for next year's color, divide it and only heat the area you have to heat.
Most of the heat is lost at the apex, and many commercial growers pull an insulated cover with a silver underside through the buildings of eves at night.
You can consider separating a double-wall polycarbonate sheet (
Light, easy to fix)
Keep it in place during the cold.
In Germany, growers pay great attention to energy, and many of their greenhouses are made of twins.
Although its permeability is poor, its heat loss coefficient (U value)is 0. 6. (glass is 1.
1 and 50mm polystyrene plates are 0. 1. )
In a pit greenhouse, you can fix polycarbonate on the top of the retaining wall to reduce the temperaturegrowing plants.
Fill all draft with putty or draft-
Proofing strips are necessary, and even protecting the structure with a fence or hedge helps to protect the structure from strong winds.
In the evening and during the cold, adding extra duvet in the form of thick wool or foam packaging to the plant will help save a few degrees.
Trying to get some extra free heat is not just for balance.
Buckets painted in black, dirt, or stone floors will heat up during the day and send out heat at night.
Make a compost box like a multi-tunnel in an alternative Technology Center (cat. org. uk), can help too.
Cat's display gardener, Chloe Ward, said they made mice.
Defense cage 1. 5m (5ft)x 1. 8m (6ft)x 1. 2m (4ft)
And invest about 800mm (2. 6ft)
Straw at the bottom.
Then they added 100mm (4in)
Alternate layers of green waste and straw, make sure to add 200mm (8in)
New materials are available every week to keep it running.
They start filling in January and take about three weeks to heat, ideal for generating mild heat in early spring to help vulnerable seedlings.
You can make a similar system with a bag from a large builder: heat it for free and then compost it.
Ecological engineer Jack stroubridge, author of Practical Self
He said he had no time to do so.
Instead, he made a hot pool in his greenhouse, which was detailed in his book.
He dug a hole with a volume of 1 m³, put in a series of pipes to let the air flow, and then filled it with broken recycled glass. A fan (a small, solar-

Breathe in air from the apex and blow warm air through glass during the day.
The glass is heated during the day, and the fan reverses the process at night, releasing heat.
They have 21 F Frost. -6C)
There is no frost inside and outside.
They had salad and eggplant in February, but also the South.
This is certainly helpful in the face of the back wall.
After last winter, I clenched my teeth and warmed my greenhouse.
There are two greenhouses that sound flash but both are at home
Made using recycled windows.
The most effective heaters are propane heaters with constant temperature control, although these heaters release water and additional carbon dioxide, which may exacerbate the fungal problem.
In addition, orchid and citrus produce too much carbon dioxide.
The latter will soon fall leaves.
The environmental concept of Alfred Brusius (biogreen. de)
Selling Propane, paraffin and electric heaters, he calculated the operating cost of their propane heaters (
Black Forest, 199)
15 cents cheaper than his most efficient electric car (
Phoenix, 199 from Amazon. co. uk).
The latter is definitely the most popular.
It runs efficiently because it has a precise thermostat that can be set to 32F (0C).
A lot of cheap will be heated frequently when not necessary, and will not be heated when necessary.
My garden Question Time colleague Anne swesinbank highly recommended it to me (
His husband tried a different one. .
Although Alfred's paraffin heaters are a new generation, they still emit messy carbon and a lot of moisture.
Because they don't have a thermostat, it's the most expensive to run --
About 50 cents more than propane.
I will plant peas, beans, Universe, lettuce, tomatoes, eggplant, leeks, cleomes, beets, carrots, etc this weekend.
If we were frozen late, I wanted to sleep soundly in my bed because I knew they were comfortable too.
