its one of many bloomboosters
i can only say that my buds did seem to improve when added
id love to have the room to test some of the different nutes available
but by reading lots of peoples experiances and results you can get a pretty good picture of what works and whats worth the money
ive got a really good grow shop 20-30mins from work + home so if i get £20 burnin a hole in my pocket im rootin the shelfs for another little pick me up for my little ladys
theres a couple of products which seem really expensive but if they make 1/2 oz difference to a crop or two its £60/80 return
if you read some of the soft secrets readers letters a lot of quality buds been grown with 13/14
