The habitats are billed as ideal for installing in and around wildflower areas, with homes for bats, birds, bees and insects in the range.
Green-tech's warehouses are "jam packed" with maintenance products for the start of the season, the company says. Its new catalogue includes turf and edging, grass seed, ground protection, weed control, maintenance equipment, fertilisers and wildflower seed.
Green-tech purchasing manager Sarah Hayes said: "We know how tough the market is and my team has been trawling through thousands of products and negotiating with our suppliers so that we can offer the very best prices to our customers."
Sales director Ian Rotherham said: "Our purchasing team have worked hard to get the right products at the right price. We have large stocks of all leading chemical and fertiliser brands. Our own brands of John Chambers wildflower seed and Advance grass seed have been repeatedly price-checked so we are confident our customers are getting the very best deals."
