O.K. so by flush you mean actually run clean water through the pot... Question? how much run off should I get..?
Light wouldn't be an issue but strangly looks like it..I think.
I use rain water, is this better than tap water to flush, also i hear to put quarter measure of nutes when flushing, It's suppose to help when flushing..???
Thanks guys... Looks like my crop is bolloxed once again...
