go to your grow shop and ask if they might have some 2oz sample bottles....i think 4OZ bottle is $20 but you might call some shops to see who stocks it and ask if they might have a sample to try as you have "heard about it" and would like to try a little...the extra yield will pay for the bottle....you only use it once within the first 2 weeks of flower and 4oz will last a long time.:thumbsup:
