You're wasting your time boiling the roots, this method is an old wives tale..

You don't get high from nutrients, you get high from THC or canaboids.

If you want the maximum potency from your buds there is only a few smiple methods to do this.

1) Know your seed stock - get good seeds, even if you have to pay for them - femenized seeds are great. this accounts for about 60% - 65% of the final outcome.

2) Don't pick to early, buds fatten up by about 35% within the final days before harvest, beware you don't leave them too late tho' or the TC will begin to deteriorate. Harvest when about 80 of the hairs are orange/brown. - This accounts for about 20% of the final outcome

3)MANICURING - don't boil the roots lol. - Remove most of the vegetibe foilage then Cut your plants off at the stems, keep the foilage. - now hang your buds upto dry in a ventilated area for 2 days, take in soem scissors and snip away any remaining leaf and tip, hang the buds back up for 4 days checking them daily, then smoke. - This accounts for about 15% of the outcome.

Growing is the easy part, anyone can take a seed, soil, sun (lights) & water and grow, the more you grow, the more you will refine your skill, experience = knowledge.

but those 3 things up their are what majorly determines the outcome of potency.
