Hi, new to the forum, looks great!! I have a quick question. My plants are 2weeks old now and growing quite rapidly. I have 2 healthy plants growing, and I will need to sex them to make sure i have all girls b4 i clone them and start my full grow. My questions are, how long should I wait to start the flowering cycle, and is it healthy for the plants to revert them back to 18hrs per day back to veg cycle? The reason for this, is I dont have 2 grow areas and Im limited space wise. Thanks!
