I am coming towards the end of my first grow and have been doing some reading and thinking for my second grow. I would like to try a wick system and I have heard some good things about cana coco.

Can anyone tell me whether they have heard that cana coco is good or bad and can anyone advise as to whether it would make a suitable medium for a wick hydroponic system?

Any help is much appreciated :mad:

Ahh - another wick grower - I'm not alone in the world. I have tried a variety of mediums and have some ideas about this wick business.

I use ordinary rockwool now - which is perfect as it doesn't retain water, doesn't hold onto nutrients and when you soak and flush it - it comes out clean. The non-retention of water is a problem for most grows - where the water comes top-down - but wick is bottom-up - so there's lots of air available to the roots - it's my favoured solution and very very cheap.

Coir should work fine too - as long as it doesn't 'cling' to anything nutewise. I've heard salt build up can be a problem - which would only be magnified when drawing up - but I'm not sure - since I've not used it.


Also - I read somewhere in 'the closet gardener' I think - that you should split the rope and spread it around the bottom of the pot. I can't agree with this - the roots are dendritic and will grow around the source whatever it's shape. When harvesting, the roots will be all around the knotted end of the wick - you just pull and it's off. If you split the rope - it'll get messy in there and make the job harder than it needs to be.

tata!

Thanks very much for the advice. A few more Q's if you don't mind.
What do you use for your wicks and where do you buy it from?
What nutrients do you use and how much?
When you say you use rockwool I was only aware that you could get rockwool in cubes, does it also come in granules, or something similar?
Lastly do you run an air pump into your reservoir?

Cheers again,

Hi all

Yep, rockwool comes in slabs but you can also get it in little cubes about 5 - 10mm across, that you use in a pot . I have just started making my own by cutting slabs into little cubes so that my plants arent stuck together on one long slab. It makes it easier to move them around especially when you wnat to flush them out.

there is a rockwool suitable for pots called greenmix i believe, it's available from growell and probably many other places. They recommend it's use in conjuction with clay pebbles.
