Mixing Ferts and Excel/Metricide

I've read about adding some excel to auto dosing mixes to keep them from growing mold. I was thinking about taking that a step further and just mixing in the excel at the ratio I needed so that when I do my EI dosing I'm also dosing the excel. I'm using Nilocg DIY liquid ferts for dosing.


Is there any reason this wouldn't work? Does glutaraldehyde not work as well when mixed with fertilizer and allowed to stand for weeks at a time? I'm not really sure how glutaraldehyde works so curious to see how mixing it will change things.

I mix Fe gluconate into Excel for a daily iron dose when I dose Excel. Since I mixed this up, though, I'm thinking there's really no reason not to include a full trace mix (I use csm+b with added dtpa Fe) since I'm dosing daily anyway - wouldn't be any more work. Should work fine for macros as well, although I'd not mix with micros/traces.

For me, it is far better to grasp the Universe as it really is than to persist in delusion, however satisfying and reassuring.

I add it to all of mine ( I have separate NPK and micro bottles) except the K that gets used up fast but the others tend to last a while (months) so I do it to prevent mold and it seems to work. Now does it have a negative effect, I don't know. But what I know is that a lot of peeps do it.

Does anyone know if the ferts will break down the glut? According to the link below glut only lasts about 20 hours after being added to the tank. Does that start once you mix it with the ferts or are you good until it is added to the tank.

Hi Pbaff,

You should be able to mix Excel with your ferts.
