Air circulation starts low down in our greenhouse but hot exhausted air can escape through the handsome full length ridge vents, located on both sides of the greenhouse for optimum air flow. Plants love air movement, you will be rewarded if you offer plenty of fresh air. To this end our vents are automated with heat sensitive cylinders and strong spring mechanisms. 6mm toughened clear glass panels allow maximum light and the openers allow maximum ventilation.

Work benches have never been so thoughtfully designed and have probably never been so strong and versatile. When installed the slatted aluminium surface will support all your plants.

You can also buy online a ABS Plastic Tray for the 8 and 10 foot wide models which can be used for potting up or to soak your pots.
There is also a hidden advantage, your staging can be folded down, just remove the tray and it will pivot down in a flash with the external frame.

The traditional dwarf wall greenhouse can be given a new look for the new century. Glazed bricks in a wide choice of colours would create quite a stir if you chose to contrast your new pastime and hobby centre to the appearance of your home. Brick bases can be a sensible but long term choice for the enthusiastic gardener, a sign of serious intent.
Furthermore brick wall greenhouses give a more even temperature throughout the structure, they’re slower to heat up and slower to cool. If you are seeking this option then discuss with your builder the plans for your new greenhouse base.
This dwarf wall greenhouse page might give you some inspiration as to the sort of bricks available.Design and price your greenhouse Building your base
All our roof and wall glazing frames have a groove, seen as a shadow line, known in the trade as a screw port. This has been designed with the grower in mind so you can fix, tie and hang plants or tools securely in position. No drilling required.
Our video shows just how easy this is using two propriety fixings which can be bought online from the like of amazon or ebay. A little creative thinking may suggest other solutions and uses. For instance, a simple screw with twine around the head would hold up your tomatoes or your electrician may use P-clips screwed into the groove to route your wiring.
The most important piece of information is however here. The screws should be stainless steel, self tapping, 4.2mm (no.8) gauge. The depth of the groove is 8mm, it cannot be tightened beyond this. A variety of screws may be required to suit your plans.
