Quick Question About Humboldt's Roots Product

i have had a bottle of this since my first grow. i dunno why i bought it. was told it was "awesome" by some dork at the hydro shop and like a dumbass i fell for it. i still have the bottle. i use Hygrozyme and love it! can i use this stuff in my nutrient program in conjunction with the Hygrozyme? what is the reason for using the HR? is it like the rest of there line, having questionable by products in it like carcinogens? please let me know. i am on my 5th consecutive grow and i am finding out the importance of taking care of your root system. i want to use it just so it dont go to waste, but i also do not want to waste it either. would it be too late to start using it just for flower? i grow in Roots Organic 707 blend and use Botanicare nutes. thanks in advance for the input!

roots is different than hygrozyme its basically the same thing as rootbastic from atami or roots excelulator from h&g, i actually got a small bottle of it to try out a couple weeks back and use it with hygrozyme and my plants seem happier than ever but on their feeding schedule it says to stop using after the stretch in flowering. id say start using it next veg cycle, only need about 2 ml / gallon. and about the carcinogens your thinking of "humbolt countys own" different company just both named after the same county.

thank you very much for the clarification. so i can use it with my Hygrozyme program? thank you kindly.
