for those of you looking for better terpene and plant development check out _"Soil Balance" great stuff really develops terp's and plant growth - a bit pricy. Have use Mammonth PH many years ago when they 1st came out . Soil balance out performs Mammonth for me- Both are good products If considering other growth enhancers look at --Massive Bloom (Green Planet)( #1 selling product) have gotten excellant yields with these products. Now i use Soil Balance (stand alone prodcuct) and Massive Bloom - got increased yields & terpen development - anyone else have experience with this product ?
