I've reused twice w/ no problems. Wouldn't add guano as that's a booster additive, right? And you want to rinse it well to get rid of any booster residue that might be left from the previous use, esp if it's really hot (Shooting Powder, Kool Bloom, etc). After rinse, charge/soak w/ CalMag & light base nutes . I've read you can add lime for ph buffering. If you're doing organic, add your worm castings & the rest. I mix in myco as well. The most important thing is the rinse.
I would use my coco 3 times.
The coco is flushed clean during the last week of flowering.
After that it is for the flower beds or vegetable garden.
Good info here. But I probably wouldn't reuse it if you used shooting powder. Never used kool bloom, so I cannot comment on that.
If you use a flushing solution, with just about any chem salt fert in coco, you can rest fairly assured that there is little left after the final flushing phase. If you're in doubt, just do the test (low EC water, record pH & EC, mix with coco, agitate for 2-3 minutes, let set, strain off and test parameters).Good info here. But I probably wouldn't reuse it if you used shooting powder. Never used kool bloom, so I cannot comment on that.
Yep, good point. It is pretty clean just from the pre-harvest flush. Why only 3 times? Have you had issues trying to re-use it too much?
Thx
canna coco, reusing it now on several runs.... plants develop severe k deficiency about 3 weeks into flower, never experienced with new medium.
Nitrogen is all but completely cut out at this time as well, it's practically nothing but phosphorous, mainly because coco already has so much potassium in it I like to keep those numbers lower unless I see a problem.
