Vegetative to Flowering time?? When tho???

Hi fellow grower, Looks great by the way! I personally like to start flowering photoperiod plants when they are atleast 35 cm in height - from the base of the stem to the top of the canopy. Or I try time it with the colder season, for example if winter is coming try start flowering 10 weeks back from around the middle of winter. This is the best for results because it will be the right conditions for flowering, give more terps and rezin and colour to your plants. If your plants are autoflowers you don't need to switch your light cycle. This is because they are made to automatically flower regardless off light schedule/intensity. The best thing you can do for autoflowers is give as much light and let it grow as big as possible as the plant is like a timer and its only a matter of time before she will be ready to harvest. I let the plant grow on a 20 hour lights on and 4 hours lights off cycle. But always keep your seasons in mind because they will affect your grow. Hotter months for growth and veg and colder months for flowering. Unless you can control your environment then no worry. In summary: I personally choose to let the plant grow as much as possible to get the most out of it come harvest time. I reckon wait as long as you can before switching photoperiod plants into flower, because you will feel so great knowing it got the best out of its vegetative stage and will result in a better yield and a happier you. Happy grow mate!
