There's a general rule that plants push more growth if nitrogen is dosed relatively higher. With me being a Dutch cheapskate, that just doesn't work: I'm not paying 30 bucks for something I can make for 3 cents and 5 minutes of my time. Most 'specialized' products are built on the cannabis-principle that goes a little like this: As soon as you specify the type of gardening/plant on the label, you can increase the price with 3000%. If I'm not using cow dung, I mix my own fertilizer with somewhat the same ratios of N, P and K as that product.īut, I pay around 5 bucks per nutrient bucket (2kg's) which will last a year or 10.
