i would also like to try the soil way....but if you do it before you harvest and put the branch into coloring..i think that will work best, so im going to do that too.
oh and PigHater, do i put the whole branch and cup of coloring into the fridge/freezer???? or just leave it out in a room?
one more thing: i think it would also work the soil way, if you starved the plant of water, a few days before you harvest, so the roots stretch for water....then a day before you harvest... just Give the plant Coloring/water ( a strong mixture of the color you want), and the plant will suck all the color right up, and send it to the buds.
P.S i am going to try my method, im almost sure it will work, i think i will add the water/color mixture for 2 days, 2 days before i harvest that is. i will give it a strong dose of color and some water. for both days. then harvest. i will keep you posted
