I'm sure plenty of you know this, but you can use old kitchen waste and other things as a convenient, cheap way to give your lovely girls some nice nutrients without braking the bank. Old coffee grinds - Coffee grinds have plentiful amounts of nitrogen, which are great for your plant in the vegetative stage. Sprinkle used coffee grinds around your plant before watering for a slow-release nitrogen supplement, you can also mix them up in your soil medium for a thorough distribution of nitrogen for your plant. Use about a half-pound of grinds per 5 gallon bucket to achieve a fast-acting liquid fertilizer which can last for a long while. Great for repellent pests as well, great for outdoor grows! Egg shells - Egg shells add very valuable nutrients to your soil medium. Mainly calcium, which is fantastic for the flowering stage since your plant eats those up pretty quickly and can greatly reduce calcium deficiencies. Make sure you grind them up very fine before adding them to your soil or putting them around your plant so they break down quickly and be used by your plants. Egg shells can also prevent bud rot in general, especially at the end of your harvest. Old vegetable or fruit peels - These have a fantastic source of vitamins and nutrients, if not the best, for your plants. Citrus peels take longer to break down and decompose and have a high acidic value, so if you use these, use something like hydrated lime or epsom salt to increase the pH. Banana peels are great for the soil as well, why? You guessed it! Sufficient amounts of potassium, which is great for the flowering stage. Vegetable peels decompose alot quicker and contain just as much nutrients and probably won't smell as bad so keep that in mine cause of pests. Grass clippings - Once again, great source of nitrogen. You can either hand pick them off your front or back lawn, or after you cut your grass, you can empty the shreds out of your bag and save them. This is a quick, convenient method for a quick nitrogen fix. You can also add leave shreds and some good bark such as cedar, pine and cypress, which acts as a mulch. These are just some of the good things you can add to your soil. I may update this in the future for people who are looking into using cheap, practically free fertilizers. Also, check out my small grow that I'm working on right now. I'm germinating up about 8 seeds right now that I'm going to plant in the woods away from my house.
