Hardneck garlic question

Talking of Effluent.

When I was 7 I spent a year living with an Aunt & Uncle near Windsor.

Uncle Graham was a keen tomato grower & had a big tank of smelly feed next to the greenhouse.

He told my Cousin & I that it was Sheep's Wee.

The years went by & I played with the logistics of collecting 40 Gallons of sheep wee.

I met up with Uncle Graham at a funeral a couple months ago & got chatting about veg growing naturally. I asked him what was really in the feed tank, wish I hadn't.

The house back then had only just been put onto mains drainage. He'd not had the septic tank drained for the last time & instead had been pumping it up to feed the tomatoes.
