Growing Slabs & Aqua Trays

Growing in slabs has been the backbone of the commercial horticultural industry for years, simply because it's stability to grow hydroponic crops, cost effectively.

There are two main types of growing slabs that we stock; Rockwool & Coco:

Rockwool, also known as stone wool or mineral wool, is the most widely used substrate for the commercial production of hydroponic tomatoes. It is also a great tool for smaller growers who can benefit just as much from its use in a range of different systems and situations. While rockwool is relatively easy to set up and use, it does require some monitoring and irrigation adjustment to make the best of its ability to hold high levels of moisture and aeration at the same time.

Coco / COGR slabs on the other hand are quickly taking over from rockwool due to having the same qualities as rockwool but also being biodegradable, which is great for the environment!
