After reviewing the actual ingredients in this product, I can mix it up myself for cheeper. However. at pure strength and applied use during flowering, my plants definitely exploded in size and sugar production. If you go over the specified amount, you will add several hundred ppm's to your nutrient solution and likely burn the heck out of everything. I use the whole H & G line of nutes. SOil A-B, Multizen, Root, Amino and shooting powder PLUS NPK fulvic acid and NPK kelp....... Cant say anything bad about H&G, except for the price.Love H&G, however saw no real difference with this product. N-p-k values displayed are not what arrives and I had no foaming/or fuzzing action.Literally works wonders have nothing bad to say start at WK 3 and be amazed by the results . It's goldkeep in mind while this product is awesome... do not use if you intend to reuse your soil.I have used this product from house and garden for years. It makes great flowers. It works as described perfectly.Works greatarrived late, used it anyways. not sure if it helped......Item arrived far faster than was suggested, which helped us out alot & the price was right.Frosty buds at the end.Love the produitShooting powder, if you think you are done, you are a moron.ExcellenyThe product works great love it. Really beefed up the flowers.
