Should I start using techniques on my plant?

Wait at least till the plant have 4-5 nodes for a faster recovery and better training. Hope it helped Good luck

Well, first of all, I think Day 15 is a little too early to do anything... secondly, since this is an autoflower, you don't want to do anything more stressful than LST - they don't LIKE stress and it interrupts their pre-programmed growth pattern so you run the risk of having a poor harvest or not having a harvest at all! I'm on Day 27 with my Blackberry Moonrocks and will be starting some LST this week on her... I wouldn't have even considered it earlier! Good luck!

Servus Mate! Well, U can train them hiwever U want. Although I would recommend to let them grow a bit taller. It's rasiert to handle them when they, at least have 20cm in height. For a Rookie in terms of Training I'd suggest LST. You might wanna have a Look at my Mamba Negra Diary. There U see some nice Pics on how I did bend the plant. If you want to go for topping, wait until the 4th, or 5th node appear! The Plants should have a root-ball big enough to survive this technique. If u Cut them earlier you risk that the plant get's stunned. Hope this helps a bit, good Luck! Servus, Oim.
