Buy Greenhouse Accessories Online - Staging, Shelving, Units and Water Supplies

Updated on April 11, 2013

Your greenhouse

So you've bought your greenhouse, and assembled it. But there are no accessories - shelving units, nor anywhere to put your plants except on the ground.

Perhaps you have bare earth, perhaps you have slabs of concrete inside so that all your plants will stand in containers, or perhaps you have what I have, a central paved aisle with bare earth on either side for either growing plants. You then have the choice of using garden soil, or covering it with black plastic sheeting to exclude weeds and putting pots on top.

Once you have your greenhouse looking the way the want, you will need to buy greenhouse accessories to make your new greenhouse fully functional.

Let's have a look at the greenhouse accessories available to buy online.

Greenhouse Staging

First things first, you need a staging unit on which to put your small plant pots and seed trays.

Palram Industries HG2001 shelving system 2 Level.

Shelf area - 20" x 46". Easy self assembly. Lightweight. Corrosion-resistant. Depending on the size of your greenhouse, you may require more than one.It all depends on what you plan to grow or even what you may wish to grow in the future. I usually find an average 8' x 12' greenhouse needs at least three staging units, and this still leaves space to grow tomatoes or other plants that grow from ground level.

Drip Irrigation Systems at Amazon

Greenhouse Drip Irrigation Systems

Greenhouses are much easier to maintain if you instal a drip irrigation system. It means you don't need to worry about your plants when you go away on holiday, for example.

The three highlighted here are complete systems. All you need to do is connect a hose to a water supply.

They can all be connected to a timer.

The standard Greenhouse Drip Irrigation system can water up to 40 plants.

The De-luxe version can water up to 70.

The Premium version can water up to 110 plants,and includes an adjustable spray head for watering seedlings.

Drip Irrigation systems not only save you time, they save you money. A constant drip drip of water on your plants actually means you use less water than if you burst water them every day. Your plants will be so much happier and healthier if you instal a drip irrigation system for them.

A drip irrigation system is one of the most useful of the greenhouse accessories.

Thermometers and Hygrometers

Greenhouse thermometers are an invaluable tool. They all should have a minimum and maximum reading so that you can know how cold it gets n the middle of the night, and how hot it gets when the sun is beating down, so that you can adjust fans/heaters accordingly.

A humidity meter is also required, because if the humidity goes too high or too low it can adversely affect your plants. A humidity meter is called a hygrometer and there are many different choices of thermometers and hygrometers on the market today.

I have listed a few here for you to look at. Your greenhouse really needs thermometers and hygrometers for the reasons I have explained here. Both temperature and humidity can damage or kill your plants if they aren't carefully maintained.

You can adjust both the humidity and the temperature inside a greenhouse by opening (or closing) doors and vents, installing heaters or sun shades if the sun gets too hot.

Thermometers and hygrometers are amongst the most essential of greenhouse accessories.

Solar lighting

Solar lights are obviously cheaper to run, but do not give out enough light to grow plants under. However, they are very handy should you wish to visit your greenhouse after dark.

Seed starter kits

Seed starter kits are essential greenhouse accessories, unless you only use your greenhouse to grow your existing plants bigger. Seed starter kits with capilliary matting, cover and water tray. Just fill with compost, pop the seeds in and water. The capilliary matting will ensure your seedling get enough water, even on hot days.

72 cell seed starter kit. Just drop a single seed into each compost filled unit and you will not need to transplant the plantlet until it is quite big.

If you have electricity in your greenhouse, this little heated pad seed starter kit is just the thing to get your seeds off to a flying start. Place it underneath your compost filled pots or seed trays and water well. Seeds sprout much quicker with a gentle bottom heat.

36 cell seed starter kit with dome cove It's better to get a seed starter kit with cover because your seeds and seedlings are not only kept warmer than those in open seed trays, but the dome also traps moisture so there is less chance of the compost in your tray drying out comnpletely. This can kill emerging seedlings who haven't yet grown a root system to go looking for water.

72 cell seed starter kit with dome cover. This is a bigger version of the one listed above and lets you grow so many more plants at once.

Greenhouse Roof hooks

Greenhouse adjustable hooks that can be connected to the apex of a green house for holding lights, fans, hanging flower baskets, fly papers or anything else you think you might want to hang.

They are a great idea and it saves you trying to fashion something yourself when you eventually want to hang something. It's a great way of saving space in the greenhouse, especially when everything is growing big but not yet ready to plant out.

Plastic roof plant support

This is a set of 10 white plastic hangers that snap in place into the groove of the aluminium greenhouse frame, to help support tall plants like tomatoes.

The picture is there on the right, it is just very difficult to see, but they are also a great idea for plant support in your greenhouse.

There seems to be greenhouse accessories for just bout everything you could possibly think of.

Greenhouse heaters

You will need a power supply if you install an electric heater in your greenhouse. However, many greenhouses can be heated with paraffin heaters, or even solar heaters. It is only in the depth of winter you would need to consider heating your greenhouse.

Unless it is extremely cold in the winter where you live, yoyu can protect your plants from frost by insulating the inside of your greenhouse with sheets of bubble-wrap, which your local garden centre should be able to supply.

Palram Greenhouse Shelf Unit at Amazon

Extra shelving - greenhouse shelving

A handy little greenhouse shelving unit to store the necessary equipment you use in a greenhouse every day, like packets/containers of fertilizers and insecticide, rooting hormone, etc

Shade netting

On those hot summer days, you will need to provide shading for your plant to avoid sunburn.

Don't forget to buy your greenhouse!

Rainwater collection - garden rain barrels

You can connect this to the guttering in your greenhouse to collect rainwater, which is always better for your plants than tap water.

There is a great range of garden rain barrels available at Amazon. Rain barrels are always welcome as they can keep your garden supplied during rain shortages or can help you water a part of the garden that is perhaps too far away for the garden hose to reach.

I'd group them in with greenhouse accessories, even though they don't actaully go inside the greenside, because you can use rainwater from a garden rain barrel to water your greenhouse plants.

Rainwater is generally much better for plants than chlorinated tap water.

      Thankd D.A.L:)

      I had great fun myself searching for greenhouse accessories. Love what is out there now. I had a greenhouse in Scotland that came in kit form and I built it myself, but it was hard work with all the fiddly nuts and bolts. Then I had to buy accessories and there wasn't half the things on the market then that there is now.

      I miss my greenhouse:(
