I read on Google that watered down coffee can be used as fertilizer. I was wondering if anyone has done this.
Sure you can but do you want to grow weed to smoke or just watch it grow for fun? You don't need anything other than soil & water, something will grow just not what we'll want to smoke. Adding coffee grounds will help a tiny bit over its life but will still produce crap imho. Add a full line of nutrients in good airy soil under a good light you can produce weed you'll want to smoke. A couple of banana's aint going to help much either unless you've prepared your soil ahead of time with full knowledge of what you need in itI read on Google that watered down coffee can be used as fertilizer. I was wondering if anyone has done this.
I think the point I was trying to make is with a full line of nute's there is no need for a bit of this and a some of that isn't going to help an already full line of nute's.Coffee grounds are filled with a ridiculous amount of nitrogen so during veg If anything. I personally don't see a need myself, but it works and won't hurt soil ph IF they are run through a coffee pot first.
