Mouldy CHC?

[Lars Kurth]

Hi,

last weekend I potted up a number of plants and as usually I used CHC for it. As the CHC came in a compressed bale, I hydrated and flushed it a few times. I had overestimated how much I needed and had quite a bit left over. I left the CHC in a box in full sun (lid open) to dry out and would stir it up every dat, such that the CHC at the bottom of the box would also dry. Due to the large amount this was a bit of a slow process.

This morning I noticed that some of the CHC in the batch got mouldy. Have any of you experienced such problems before? Obviously I need to dispose of the remaining CHC, but I am now rather worried about the freshly potted up plants.
