Rainwater Diverters

If you’re looking to harvest rainwater from your cultivar greenhouse then we have options. All our greenhouses come complete with rainwater goods which include strong aluminium guttering and neat aluminium downpipes. The downpipe external diameter is 40mm which is a common size, this means that proprietary push fit fittings from the likes of Marley and FloPlast are readily available online, at your local B and Q or plumbing merchants. So if you have a need to send the water from your gutters to a particular area this can be readily achieved.

That said we are yet to find a rainwater adaptor suited to this common pipe size. Most seem to be produced to harvest water from large house downpipes. We have however found a 50mm diverter from FloPlast which we can get to work with our downpipe. We do this by 3D printing a set of collars to bring it to the right size. We’ll buy the diverter, and do the work of adapting it. So if you’d like to add a complete diverter to your order prior to installation then let us know. If you have your waterbutt in position ready on site when our fitting team are there to assemble your greenhouse they can hook this up for you. If you already have a cultivar greenhouse then we will likely have stock and we can put one in the post. Why not watch our video to see how this works.

Collecting rainwater to use on plants an eco-friendly practice. Firstly, rainwater is a natural resource that’s free and abundant. By capturing and storing rainwater in water butts, you can reduce your reliance on municipal water supplies or wells. This not only saves you money on your water bill but also conserves precious freshwater resources. With ever changing seasons and long periods of dry weather, rainwater harvesting can be a crucial strategy for preserving local water supplies and keeping your precious plants healthy.

One of the primary benefits of using rainwater for plants is its purity, it doesn’t have the chemicals you find in drinking water. This makes it ideal for many plants, especially those sensitive to hard water or chlorine. Using rainwater can help prevent mineral buildup in the soil and ensure healthier, more vibrant plants.

Additionally, rainwater has a pH level close to neutral, which is generally suitable for most plants. This means you won’t need to worry about pH adjustments in your garden, simplifying your gardening routine.

Water butts are versatile and can be easily integrated into your gardening setup. They can be connected to downspouts from your greenhouse roof, allowing you to collect large quantities of rainwater during storms. Most models even come with a tap for easy access, making it convenient to water your plants with a watering can.

For greenhouse enthusiasts, water butts are particularly valuable. Greenhouses often require consistent watering, and the controlled environment can magnify the effects. By using rainwater, you can maintain the ideal conditions for your greenhouse plants without subjecting them to the potentially harmful chemicals found in tap water. Not everyone has mains water running to their greenhouse so unless you want to traipse back and forth to the house with a watering can or run a hose back and forth there’s another good reason for collecting it directly from the roof of the greenhouse.

Furthermore, using rainwater can contribute to the overall sustainability of your garden. By conserving water and reducing your reliance on municipal supplies, you can make your gardening practices more environmentally friendly.

An attractive aged trough makes it quick to fill a watering can by dipping.

And here’s another one, not quite in use yet but you get the idea. Notice the additional pipe spanning the rear of the greenhouse so water can be collected from both sides of the roof.

In conclusion, collecting rainwater in water butts and using it on your plants is a practical and environmentally responsible choice. It saves you money, benefits your plants, reduces water pollution, and promotes sustainable gardening. So, invest in a water butt and harness the power of nature to nurture your garden. Your plants, and the planet, will thank you for it.

A newly fitted greenhouse in a modern garden setting with a small water butt on a stand. The stand is critical if you are to fit your watering can under the tap at the bottom of the butt.

A water trough raised on concrete is an practical and attractive solution. Seasoned Horticulturalists know that a Haws Watering can has a wide opening for ease and speed of filling in such a trough.

This plain end of a modern aluminium greenhouse has been furnished with a equally modern tank. If you opt for a 2 gallon Warley watering can from Haws these have a particularly wide opening at the top which, when dunked, fills up in seconds, providing of course that you have enough water in the trough. Having a small bucket to hand might be useful for scooping out when water levels are low mid summer. The trough is available from a company called ‘dip tanks’, it looks to have been colour matched to the greenhouse (RAL7039).

If you don’t like the idea of a pedestrian plastic barrel then there’s always the option to go for something like this Greek Urn Water butt.
