This seems to be pretty good stuff; we used it for about 6 varieties of chilli grown from seed last year and nearly all of our plants grew very vigorously and gave plenty of fruits. The only exception was the Tabasco seeds (not purchased from SDCF!), which I later found are quite hard to grow anyway. As we gave it to all of our plants, I can't really compare the effects with plants we did not feed, which is why I rate as 'very good' and not 'excellent'. Got to be worth a try at a couple of quid!
Just ordered another 3 bottles, really good stuff, within a week of feeding as per the easy bottle instructions BIG improvement to all my plants. It's like steroids for chilli. Healthy looking plants with plenty of fruits.
