When to start flowering

hello i am just writing you asking when is the best time to start flowering,
i have been vegging 5 THC bombs under 400W bulb in a hydro set-up for 5 weeks and was wondering when is the best time to start the smallest plant is 18" and the tallest is 24", some advice would be amazing thanks .

I think it depends on how tall you want your plants, but normally plants veg for about 8 weeks. I'm sure you could start it now by changing the lighting, but if you have room I'd let them get a little bigger.

Hope that helps.

Yup depends on how tall you want them and how much room you have before they get to close to the light. The bomb strains tend to get tall and grow heavy buds depending on your head room I would also flip now. Good Luck..

i have not so much room abour 10ft upwards an 3ft in length and width.
