Description
These Coco Slabs by Canna are super easy to use and make growing cannabis an easy process. All you have to do is place the slab on a growing table, attach the drippers and transplant your clones or cuttings. This innovative growing system allows you to grow lots of plants in small spaces, increasing productivity by quite a lot.
Canna’s coco slabs contain quality coco fiber that has been treated and washed in order to get rid of any dirt and pathogens; it doesn’t contain minerals of any kind. It’s the perfect medium for your plants’ roots, as it retains quite a lot of water but is still quite airy, giving your plants’ roots constant access to fresh air.
In order to get started, simply place the unopened packet on a growing tray or a Pot For Slab With Drains with the pre-perforated part facing downwards. Attach one dripper per plant and cut an X where you’re going to plant your saplings or clones. Hydrate the slab using a nutrient solution with a very small amount of nutrients so you don’t over-feed your plants. Make sure to include a small amount of root stimulant to entice growth.
Make sure that your set up can drain off correctly and that excess water has a proper outlet. Make sure that all of the drippers are working properly, including the connections; if the slabs dry out or end up too wet your plants may die. You also may want to check your nutrient solution every now and then in order to make sure that you still have water left and that the pumps are working correctly. It may be an easy system to use, but there are a lot of working parts that may end up malfunctioning.

Good product overall. I used it with my drip system and didn't have any clogging issues, which sometimes happens with other coco. The pH stays pretty stable, which is a relief. The only thing, a bit pricey compared to other brands, but you pay for quality.
Translated from Spanish
Buen producto en general. Lo he usado con mi sistema de goteo y no he tenido problemas de obstrucciones, que con otros cocos a veces pasa. El pH se mantiene bastante estable, lo cual es un alivio. Lo único, un poco caro comparado con otras marcas, pero la calidad se paga.

Average, does the job. It's not the best I've used, but not the worst either. To get by, it's fine. Would I buy again? Maybe, if I don't find anything else.

It's good, does the job. The only thing is that at the beginning you have to flush it a bit more than usual to stabilise the EC, but once that's done, it runs like a dream. The plants really appreciate it.
Translated from Spanish
Está bien, cumple su función. Lo único es que al principio hay que lavarlo un poco más de lo normal para estabilizar el EC, pero una vez hecho, va como la seda. Las plantas lo agradecen un montón.

Good substrate, delivers what it promises. The germination rate in this coco is high, indeed. I have used it with Canna nutrients and the results are always consistent. A bit more compression in the packaging would be nice, but that's a minor detail.
Translated from Spanish
Buen sustrato, cumple con lo que promete. La tasa de germinación en este coco es alta, eso sí. Lo he usado con los nutrientes de Canna y los resultados son siempre consistentes. Un poquito más de compactación en el empaque estaría bien, pero es un detalle menor.
