I’ve read nothing but good about Purple Cow Indicanja and have wanted for a while now to try some. It arrived yesterday but can I start a seed in it? If not what about a 50/50 with some Roots Organic? I also brought my earthworm colony in because of the cold and moved them to their winter home. About 500 of them in a bin I got started back in March (8 months ago), and man that dirt is black! How much of that could I use? This is for starting a GG4 seed. Thanks.
