Growhouse newbie. Advice on shade net, thermometer, venting, etc.

It may not be completely frost free but you will get some additional protection as it’s against the house and will get some warmth from the wall.

We grow all our tomatoes in the GH through the summer, ditto cucumbers and peppers

Mint is perfectly hardy so don’t waster any valuable space in the GH

 

For your space look at the smaller bush cherry types like Tumbling Tom or Maskotka , the larger Cordon ones grow 6 -8 ft so need to be put outside once growing strongly.

Too small for frost protection ?? as long as you use some bubble film in winter to insulate it, should be able to fend off most frosts, though if you can put electricity in there, either mains of solar/battery it would give better protection.

Fuchsias generally like warmth but shadier condition so too hot and sunny will not do them any favours.

If its hot and dry then like a gravel tray, cap matting will help keep the plants /environment moist.

Worth chucking them in the growhouse in the evening or on cold days?

For sure, thats one of the biggest plus points of your greenhouse / cold frame.

 

Shade netting arrived (went for 85%) and it certainly makes a huge impact on the temp I could feel behind it. We've had pretty poor weather, lots of cloud cover and more rain, so limited experience with it.
I realised that are really aren't any anchor points for the netting, however have managed to just tie two of the loops together around a corner bit of the growhouse and it didn't come off in this high wind.
Will need get some more for the sides, and work on a neater attachment solution.

The shade netting means that the shelves can be used without burning things to a crisp.

Although I have been a bit naff at remembering to properly water the Photinia cuttings, at least one has actually grown roots over the Winter! A few others get that crumble bobbly stuff on the end of the cutting but were otherwise a bit dead looking. That looks to be the pre-cursor to root formation.

 

..tempted the fate. Went outside to shut the side gate and found the netting on the floor. Have tied another string and put that around a brick. I don't think it's going anywhere now

 

We screw some smallish (eg 25mm )Cup Hooks into frame so we can secure the netting / timber battens to them.

The shading is more effective if its reasonably taught across the framework so there is a small air gap between the glazing and the netting. This allows the heat to be vented before it can pass though the glazing.
