This is Bad!

ahh, right, i understand now, thanks, spirit:)

i didnt realise that. That kinda adds a whole new dimension to consider....
i never really considered organics......must do some reading...

Yeah, SpiritLevel explained it perfectly.

When you do your next soil mix you don't have to add a fibrous material. Just go with the perlite/vermiculite. As something like coco fiber breaks down, it can hold moisture too much, making it harder to flush, feed, etc.
I like my soil mixes to be light and friable.

Believe it or not, I am certain the soil mix I buy from the growshop is second hand. I like to work my fingers through the bag to ensure there are few lumps and bumps before potting. Not only that, I like the touch of some mixes and I can more or less feel how a plants roots will feel when the are bedded in it. I've found shreaded roots and clay pebels in tens of fresh bags of special mix. It does the job, but I do wonder if I can recycle my own soil with the correct additives and methods.

im sure it can, like cutting up old root balls and mixing them up with other stuff...food scraps etc. kinda like normal garden composting i guess...

im no expert though, i couldnt grow a good rose bush or anything lol
