Friends, my plants are about 6 weeks old and about 60 cm tall. How many weeks do you think it will take for the plants to reach 12/12 light and start flowering? My tent is 2 meters high and the potted plants are now about 1 meter high. I want to change the lighting from week 8 #Grow Cycle > Flowering#Indoor Growing > Lighting ---

If your plants are half the height of the tent I would change the flip from week 8 to now. I would say generally speaking they want to stretch about half the tent height thru flower. So flip em like a pancake baby. 🥞 ---

Take in consideration plant will double in size. When flipped to 12/12 light schedule to start flowering stage. Good luck ✌ ---

I agree with everything above, but will add that topping or training your plants will give them time to get wide and slows the vertical growth. I top, train, supercrop…as much as I need to to get 4 plants to fill a 4 x 4. I like to keep them under 55 cm at the flip or I run into height issues. To get a flat canopy, I usually have to cut a few nodes down on some plants. Show us a picture of your whole tent…easier to see what you have going on. ---

Also, flipping to 12/12 before sexually mature is a waste of time. ---
