I emailed envirolite and asked them if its safe, they said I should throw it out, but I should be ok unless I got lots of "white powder" on me that was inside the bulb- I didnt, so I should be ok. Gutted about throwing it away though, it has had about 15 min of use!

I live right in the center and there are no shops here that would sell soil- Id have to get two busses to get there today (since the seed is ready to plant)- and Iv got other things to do today so I cant be bothered.

I wouldnt mind flushing out some of the goodness if it would also get rid of the extra nutes- it would only be until the 3rd ish set (like you said), and then I would put it in the huge pot with new all-mix and that would give it all the goodness it needs to grow in veg state.

Heres the plan:

The all-mix in at the bottom of the pot can be slightly flushed/washed with water before I put it into the pot to clean out some nutes.
