I've seen organic nutrients in the hydroponics stores and websites, but the prices are outrageous. I don't use organic, I really don't see a problem with using chemical fertilizer. nitrogen is nitrogen as far as the plant is concerned. I'm more concerned about pesticides, and bacteria from unclean food handling processes.

but, one thing I've heard of people doing is using compost to make organic compost tea. if you have the space to make a compost pile, or if you have a source of compost, you can make your own organic nutrients.

just put some compost into something fabric, like a burlap bag, cheesecloth, etc. then soak it in water for a couple of hours, like a giant teabag. the nutrients end up in the water and you can feed it to your plants. just make sure the compost is nice and loose inside the packet, so that the water can flow through it.

I have read "Compost teas have too much ammonia for use directly in the res. If you use a biofilter in the res, you can get away with more 'organic' processes, but the best way is to make a separate biofilter processor for the teas. A biofilter will 'eat' the ammonia and proteins and turn them into more usable forms of N." - duggreen

The ammonia can effect the PH levels of the water in the soil or in this case coco coir, which could have dramtic other effects, like root burn and such.

I do agree with @kleeem that organic prices for nutrientes are high. The synthetics are way cheaper and give you higher amounts of nutrientes; however, if you are organic then you are in a pinch.

I would suggest going to a local grow store or leafing through a Maximum Yeild magazine. They both should be able to give you a good idea of what is on the Market and from their you can allow the price to guide you where to go.

I am experimenting using humonia as a source of Organic fertilizer, you need to supplement it with Organic source of Iron and Phosphorous, so far it is successful in growing Mints, Arugula, Swiss Chard and Cucumbers in a mixture of pebbles and clay balls! :) SZ

safwatzaki,

Could you provide a link to what humonia is? I am having a
hard time finding it on Dr.Google.

Humonia or peeponics is used to grow plants Organically, here is a discussion how to use it
