My whole approach to growing is to spend as little time as I can doing it. I have much more important things in life than to mend plants. I would like to share with you some time savers that I swear will make life so easy for you if you are mixing in a bucket Battery Operated Kerosine Pump. Pretty common these days but I have a suspicion that I may have been one of the first to use them because nobody else was at the time, plus I lived in a country where everybody used kerosine heaters. Plan on replacing these about once a year. Could not think of transferring nutrient solution without one of these. These are called safety wash bottles on Amazon. I fill these with my nutrients and pH products etc. I use these to squirt everything I need into... 100 ml plastic Graduated Cylinder Beaker to measure your nutrients. I don't bother washing it out between my gh 3 parts, I just do it quick and then shake it with water when done. Using these 3 tools and a bucket it takes me 11 minutes to fill 2 X 3 gallon buckets, mix and feed 4 plants in 5 gallon pots in a 4x4 tent. Or 3 hours for a whole grow in drain to waste setup.
