Thanks,I found it.
It can be used as foliar feeding and as an additive durring the flowering sycle,or atleast thats what the listing on ebay states.
It also stated it could be used with GRAVITY.I also found this listed as Humboldt County Gravity Foliar.Do you think I should get both or would the first ones that you recomened be enough?

This is the link to the ad for the Gravity foliar feed:
Humboldt County Gravity Foliar Hydroponics HPS 8 oz - eBay (item 280224834284 end time May-13-08 19:24:23 PDT)

And for the PURPLE MAXX Snow Storm:
HYDROPONICS Emerald Triangle PURPLE MAXX Snow Storm 8oz - eBay (item 270160586882 end time May-25-08 20:37:45 PDT)

Please tell me if these are the right ones.And thank you for your help.
