i got the lighthouse 90w for veg. the biogrow isnt the best as you say kang, i dont like the npk. i much prefer the fishmix now for veg, it seems to make the plants much more greener. higher n in it aswell. it does smell a bit though. i had to floiar feed it at the start of flower for n def, the whole fukin house smelled like a fishmongers. i think even the nieghbours were looking at my missis funny aswell!lol!
another thing with the bio stuff is i always have to use algamic for the micro nutes. also they do drop the ph a good bit aswell. grow and bloom will drop my ph from 7.6 to about 6.3-6.4 which is why i like it so much. the bloom bastic at the end of flower works a treat for frosting up the buds, you should give it a go!
