Bloom booster?

I personally play around with GH's boosters and have no experience with h&g.. Seeing as how you're newer to growing I would recommend going a whole grow without any additives and then adding them one at a time in your next grow.. It doesn't do you any favors to use boosters on strains that you aren't experienced with.. I say this because you may be wasting your money; reason being, you don't know what a good yield with your particular strain should be WITHOUT the additives. When you do start adding them you want to look for improvements to see if the product is legit, or if it's just bullshit aimed at taking your money..
