Yeah but they didnt just do that they girdled it too basically you cut round the stem but not all the way through and that cuts off the nutrients and water etc helps it turn to gold as well as the dry on the vine method almostI typically start them indoors as the temp is going to be in the mid to high 60's. Not the best temp for veg growth. I will usually grow them to a bit more than 12-14 inches then sex them by a 12/12 light regiment. By about 6 to 8 days they show me who they are going to be and I decide what I am going to do.
Next, the days have started to warm up. So then they go outside for flowering and finishing. I find the taste to be much better outside then in. Also the long FREE light helps bring better blooms than inside. When they ripen up then I harvest. I have never done the acapulco gold method of letting the dry outside in the sun while still rooted. To me that dirt weed taste can be saved for someone else.
