growing things in a plastic green house (flower house)

the problem if your trying to grow normal garden plants isnt the heat as such.plants from a temperate region like carrots,peas,tomatoes,apples etc you get the picture are on an internal yearly clock defined excuse my spelling bye the amount of sunlight they get.the only way you can cheat them to grow is to cut out all the natural light all together ie black plastic like a mushroom growing place and replace it with un natural light copying the amount the sun would give out on a timer.autumn is 12 hours light and the same dark.you can give them 12 hours light and 6 dark.in the vegative growth stage you can give them 24 hours light but you cant let any sunlight in.i dont know if this is good or bad news but at least you know now. i hope this has helped take care bye for now

i did some last winter.all we did was to insulate it with bubble wrap then place a themometer to keep a check.hope this helps.

If what you have is the same as mine (see photos of my "greentent") I grew things in mine over last winter. I had lettuce, spinach, kale and chard, with a handful of carrots. I also used it to get an early start for my summer plants, peppers, eggplant, basil etc.
Now my climate is warmer than New Hampshire, so all I needed through the winter was a small space heater, the kind used in dairy milking sheds.
Hope this helps you out, and good luck!

you also might want to try some items that like the cooler temps like boston lettuce or therare actually quite a variety of lettuce that will grow with just a tent over it thats in the sun for most of the day there are also onions, garlic and carrots.

good thinking love

The best things for autumn and winter are short season plants like Chinese cabbage, Chinese greens like mizuna and mibuna greens, Lambs lettuce or 'mache', and winter radish etc. These should be sown soon and the plants will last well into the winter if you use the 'cut and come again' technique. If you are referring to flowering plants, choose things that flower in winter or early spring. You can get much earlier flowers on many things like daffodils, crocus etc.
If you are talking about vegetables, with planning you can get very early crops of things like peas and spring cabbages, followed by crops of French beans, and then your normal summer crops of tomatoes, aubergines, peppers etc.

I haven't got a plastic GH but I do have an unheated glass one. I've had success with growing the mizuna and mibuna as mentioned by Bertie and now I plan to do it every year. Komatsuna is another good one - I use baby leaves in winter salads or bigger ones in stirfrys (although it starts to take on a bit of a 'hot cabbage' flavour with the bigger leaves). Some seed companies may sell mixes of 'oriental' veg so you might be able to try out a few in one packet.

if you pull the leaves that look a bit rough of a lot of trees and when i say the leaves you must pull the leaf from of its stem it will grow back.i learnt this of a bonzi growing friend of mine.works great on my acers if i get the odd scorched leaf.he does it to all his leaves during the growing seasen so he gets hallf size leaves
