Well I'm growing in soil, so the ratio would be different, but I use it half strength untill they have buds the size of the end of my index finger, then I use the recomended amt. I've been using it on everything, houseplants, oregano, all of it! Love this shit! Can't wait to get started with the Tiger Bloom! I bet that will make african violets EXPLODE! It would have to be awesome for organic loving gardenias. Its a pitty it cost $25 a bottle, or I'd even use it in the garden! But at that price, its only for the grow!
