Dry nutes???

You're looking for dry amendments. They're a slow release fertilizer that you mix into your soil, you should only have to re-amend once every six weeks or so. Using those all you have to do is water and they'll do their own thing. Having not used them I can't recommend any brands. Happy growing.

Yes there is dry amendments try Dr earth I'm using it right now go in YouTube and type dry amendment grow and they will break it down for you every 4 weeks you'll mix in the dry amendments the first time you'll mix it in with the dirt and the four weeks after that we should be your bloom you will put it on top of the dirt and then mix it in real easy all you got to do is pitch the water to 6.8 every time you feed

Hi mate, I use Green House feeding Bio line and its awesome. I add at the beginning and then at start of flower. Dry amendments with an 8 week life. I think its more 6 weeks for me as my CO2 is high. I hope this helps, good luck and happy growing
