I wouldn't pinch them unless your tight on space and rather than pinching them I would LST them, better results and better for the plants. Also like
Kush07 said, you should wait until your plants are ready and show you there pre-flowers or you'll probably have problems getting them into flower and bad results durning flowering.
smoky mcpot 05 Reviewed by smoky mcpot 05 on . When to start flowering??? It has been 1 month since my seeds germinated, the guys from Green House Seeds told me that i should start flowering after 10 days or so, if i want to have a final height of 60-70cm at harvest time. I guess they were talking about 10 days of veg period. So would be too early or too soon to start when my babes are around 20-25cm tall???? And do i really need a 3 gallon container to grow a plant that wont be taller then the height im aiming for? Hoping for some help in these matter!!! Thanks Rating: 5
