Canna Canna Coco Brick 40l Expandable Natural Plant Medium Soil Substrate, 40 Liter Expanded - 8 Liter Dry, Reusable (1)

I decided to try my hand at growing cannabis this year with having extra time at home on my hands. I chose to grow in both soil & coco. I’ve never used coco as a growing medium before but neither have I grown marijuana in soil either so I figured it would be a learning process. So here I am 5 weeks into flower and I can say that I’ve had much greater success and way less issues w the plants grown in coco. Same strain, same germination date, same everything but medium. The plants in soil went through and survived mites, nitrogen toxicity, calmag deficiency and fungus gnats. The plant in coco has had zero problems at this point. It’s bigger, stronger and has more bud sites which is a direct result of less stress during veg. Less problems means less stress. See where I’m going here? I know that when growing in coco, it is a neutral medium so there are no nutrients. They must be added especially calmag which is a very common deficiency using coco. Many times growers end up w toxicity from adding too much nutrient solution.. But for whatever reason, I haven’t had any issues. Perhaps the amount and way I feed fits coco best? The coco was easy to break up and transfer to the planters after adding the appropriate amount of water. It only took me minutes to break up the entire package of bricks. It was clean and didn’t contain any unnatural material or ingredients. For me, even in the hot 110 degree plus weather in central cali, I only had to water my 5-gallon plants once a day. They retained the perfect amount of water but not too much so they didn’t take too long and get soggy, drowned roots. In the future, I think I’ll skip the soil and go w coco all around. Plus it’s reusable! It’s much less messy than soil and has a better natural defense against pests. As I mentioned, my plants grown in coco didn’t suffer from the mite issue even though it was next to the ones that did. I’m incredibly impressed w all aspects of CannaCoco and will be buying & using it from here on out. Happy growing & safe harvest, 2020! Update: 6/21/21: Once again I’m growing and needed more coco. I’ve gone coco loco!! Before buying, I took a look at my last years leftovers and decided to re-use them because let’s be honest...this stuff is experience. The canna coco was the only brand that held up over the winter as it sat untouched in the greenhouse. After a few rinses and de-rooting what was left from the previous plant, I was easily able to re-use all of the canna coco. Not so much w the other cheaper brand which I ended up tossing. This meant I saved $ and have had no issues w my current ladies being planted in re-used coco. I know many brands claim their coco is re-usable but most aren’t due to the time it takes to clean it, etc. Canna Coco doesn’t lie! I saved $120 this season alone by investing 30 minutes in cleaning my old Canna Coco. Let me also add that after using both soil & CC last year, I’ve converted to 100% coco based on my wonderful results from Canna Coco. It also dries out quicker which can be a great thing at harvest when trying to decide when to start flushing-for those that do!

Absorbs water quick and beautifully and creates verrryy high quality coir. The best coco coir I have ever used. No issue absorbing water at all and creates so much for the price. Took 1/4 of a brick to fill up a gallon pitcher. Amazing.

Best coco coir out there IMO. Really like the size and the fact that each block comes with its own bag to rehydrate them in. No mess , just open , place in bag and add water. In minutes you will have ready to use coco coir. One block is perfect amount for filling 2-3.9 gallon AutoPot containers. I have used with and without adding perlite (70/30 ratio) and seen no noticeable difference in plant performance. Very high quality at a very reasonable price compared to buying bagged coco coir, plus the blocks don’t take up a lot of space waiting to be used like bagged mixes do

After months of battling soil infestations in my potted plants, I was forced to resort to chemicals in order to destroy the plague. My plants were incredibly stressed and the pesticides further damaged them. After this experience, I decided it would be best to start building my potting soil from scratch so that I know for a fact what is in it. One of my requirements for a soil building base was to use material from renewable and sustainable sources. Coco Coir fulfilled that requirement by a landslide. But further research on Coco Coir revealed that not all Coco Coir products are the same. Due to its natural environment, Coco Coir tends to be heavy with salts from the nearby Oceans so it needs to washed and then buffered so that it does not disrupt your soil ecosystem. Also, for some reason, alot of brands tend to add extra fertilizers. This is where it tends to be difficult to identify which brand is best. The Canna Coco brand is incredibly clean. It has a slight earthy smell and once a portion of the brick is soaked with water, it quickly expands into a very soft base. I strongly recommend using distilled water if possible. I love it so much I decided not to cut it with perlite or vermiculite and simply added all of my powdered minerals and earthworm castings directly to it. The Coco Coir absorbed and held the powders quite well. I planted my seeds and seedlings directly in it. Germination times were off the chart (in my records at least). My seeds germinated, sprouted, and grew two inches in less than a week. I transplanted 1 foot tall plants into it and white, fuzzy roots were shooting through the media within the week. Another great characteristic of this product is that it dries out quite nicely. This is important to prevent root rot. Peat moss (the forbidden and oh so delicious fruit... it isn't a sustainable resource my forest friends!) is amazingly absorbent but that is also a downfall for it because it tends to hold too much water so mixing it with perlite or something similar is a must. Coco Coir, on the other hand, breathes very well on its own. I look forward to using this product and brand regularly. It is quite expensive but for a vegetable garden it is necessary. I look forward to seeing how my worms enjoy composting it so that I can recycle as much as possible. Happy Gardening folks!

Very happy with this coco. So far I have had 0 issues with it, no fungus issues, and so ecstatic that it came in the bag to mix it in to start, instead of prior ways of dealing. It smells good, very earthy smell. And has good drainage but still holds water well. This is the best coco I've used and intend to buy again. My plants are thriving and I'm able to keep everything in check with my nuits and ph. I go with ac infinity and vivosun for most of my products but this beat ac infinitys coco.

The best coco coir brick on the market. It's easier to store and expands to a nice fluffy consistency.

Love it!

Easy to use
