Has anybody used BMO with coco? I've been reading that you should only use nutes that are specifically made for coco, but Ohso says that that you can use BMO with coco. I was just wondering what your results were if you did. When hand watering coco, people usually water til they get 10-15% run off to make sure there is no salt build up. If using BMO with coco, would you need to worry about salt build up? I don't mind watering 2 times a day if I have to, 15% run off is a waste of nutes IMO!
Ohso your thoughts?

D2G.... I also think that amount of runoff is a waste. Here is how you avoid that waste. Go to Wal-mart and in the isle with flower pots, pick up a clear plastic pot drain pan (sold to keep you indoor potted plants runoff water from ruining the carpet) for each pot you have.
.
Before you fill each pot with coco, cut and run two pieces of 1/4 nylon rope (wicks) out the bottom, thru the pot drain holes. Just thread your wick in one hole then out the other side, so you basically make a U shape with each end of the wick sticking out the drain holes a couple of inches. They don't need to be very long, just enough to help drawn in water / nutes.
.
That way, you can water / feed only until a slight runoff is seen, then stop. The excess will sit in the drain pan and be wicked back into the coco by the wicks. Just keep the amount of water in your drain pans, like under 1/2 inch (max).
.
Then once a week, remove, wash & rinse each of your drain pans (aka-overflow reservoirs). To avoid a build up on nutes in the coco, just feed, water, water, feed, in rotation.
.
Any nutes can be used with coco, if they have higher P & K numbers. Since coco tends to lock up P & K, withholding it from your plants roots until enough is present.
.
I'd just start off with 1/2 oz of GIG (NPK 5-2-5), and a light dose of FP (NPK 1-8-7), like 1/4 oz per gallon of water. That would give you a NPK value of 5.5 - 6 - 8.5. Then the very next feeding, use only 1/2 oz of FP (NPK 1-8-7) per gallon of water.
.
The key to this strategy is simple. A good amount of the P & K just get locked up in coco, there is no avoiding it. So you have to give more P & K thru the whole grow. By alternating fertilizer mixes, you let the N get used pretty much as you go & keep just enough extra P & K to ensure the roots actually get what they need. Since, that coco is going to be holding onto & not letting go of a fair amount of P & K.
.
Depending on the strain you are growing, you may need to feed more (slightly stronger mixing strength), but probably not less.
.
The feed, water, water, feed, in rotation - is basically a ongoing light flush that helps avoid build up of nutes in the medium (coco), so Mary stays happy & healthy......

Hope this helps.....
