1 1/2 80mg tablets to 2 galls.
A litre would do my whole 'house, so I need about 1/15th of a standard 300mg aspirin? A bit tricky? And could that dilution really[/i work wonders??
I've been spraying mine Tim at fornightly intervals. Trouble is I've sprayed all of them so don't have any tomatoes, peppers, aubs or melon or sweet potatoes unsprayed for comparision. I just didn't want any of them to go down with anything nasty. I seem to be using about 1/2 gal. a go, just shelve the rest, give it a good shake two weeks later and use. My plants seem quite strong and healthy, but they might have been anyway.
