since you don't know when to go to 12/12, (which i told you is last week of flowering for autos, ie; 7th wk if harvesting in 8th wk, or 8th wk to switch to 12/12 if harvesting in 9th wk or 9th wk to switch to 12/12 if harvesting in 10th wk)......this method, mostly for reg. strains, which you are growing also, can also be applied to the autos as well....If you don't want hermies switch to a waining Light period.
This light period is one where you gradually dial back the light cycle one hour at a time for a week for each hour. This process takes 5 weeks. After you reach the 12/12 is when you start counting your flowering time.
It also works well with Indicas, because you will see pre flowers with in the waining light cycle... (it also makes your buds slightly bigger with indicas)
DJ Short alludes to it in His book, "Cultivating Exceptional Cannabis". The reason behind this is because you can not expect a Sub-equatorial strain to switch to 12-12 overnight.The region where they come from doesn't do that and neither should the grower. The Light cycle is genetically programmed into the plant. Any deviation from that will result in Hermies.
The Object is to try and duplicate nature.
when will you know to go to 12/12 because i have other plants that are not autos so i just move them in and out. Also could i go the last week and a half or only the last week with 12/12? Check out my page and you can tell me what you think so far because they are on day 30 right now so only 40 more days hopefully!
