Marco 02-04-2020 Has bought this article Wich dimensions does this have? I need the diameter of the hole needed and the parts that stick out in front and behind the hole. Thanks
Alchimia Grow Shop 06-04-2020 Hi, this drainage valve has an internal diameter of 30mm, so it's for a 1 1/4" hole, around 33mm. The flat side of the valve sits more or less flush with the surface while the other side protrudes around 60mm. I hope that helps, best wishes and happy growing!
