    so here's my question I need to break down these blocks of coco coir I bought botanicals growblock supposedly less salts so here my deal I was thinking ph my water and ad silica blast + cal mag plus they are both buffers for Coco so do I just rinse it like 3 times just ph the water add my buffers and soak like 30 minutes each time then wring it out real good do the same 3 times till my waters ph stays the same? Anyone got experience in coco let me know what's up

    Hydroton (clay pebbles) is the best medium for flood and drain or ebb and flow. It stays wet enough to keep roots from drying but allows maximum oxygen to the roots too. You get the most out of that sort of system because you can flood it multiple times day and night.

    That said as far as coco goes. With block coco I soak it for 24 hours with a cal mag solution and then I put it in a bucket with holes which is lined with a pillow case. I put the shower head over it for 30min, agitate it, when it runs clear I squeeze out as much moisture as possible.

    Going back to flood and drain, I would be worried about the drains blocking up with coco, if that happens you may flood your grow out. Or it doesn't drain properly which will result in a lack of oxygen at the root zone. Not sure what system you have but the one I built was recirculating, I don't think you can recirculate nutrients in coco. Once its gone through the coco the EC and ph changes, maybe it can be used if nutrients are reduced considerably. But I would be doing more research. I feel though that using coco in flood and drain is going to cause problems and not make the most out of the plus points of flood and drain. One of which is when water floods and then drains it acts like a suction pump and draws fresh oxygen (lots of it) to the roots and that's what causes such quick growth and good roots. I feel that would be drastically reduced in coco due to it holding a lot more water.

    Still I would be interested to see if anyone else has success with coco in flood and drain. :bigjoint:

    There are levels of anal we all pick.

    What I do is a bit simpler, my coco doesn't have much salt, water ppms change about 30ppm after adding coco. So, I don't rinse.
    Take the amount of water you need, add Cal-mag at a rate of 50g for every 20L, stir well. If the water is fresh out of the tap, let it sit for an hour or two to gas off some CO2 from when it was under pressure n the pipes, this gives a more stable pH. pH water, add coco to soak for 12 hours, drain excess water off and mix the coco well to distribute left over water evenly.
    Add plants or seeds.
