Parkside LED mini-greenhouses cost less than 10 euros at Lidl. This kit includes five mini greenhouses with five inserts that can hold 12 plant pots each.
The transparent lids have adjustable vents and each mini greenhouse has its own LED light that can illuminate the plants to encourage their rapid growth. The objective is to obtain seedlings which you can then replant in the ground or in a planter to accelerate their growth. You can also use minigreenhouses to grow aromatic herbs indoors and consume them directly.
