Help

This is my first grow and I was wondering when I should flip to flower. My biggest one is 16” and the smallest 13”.

Depends on a lot of stuff. Plants look good. They will most likely get 2.5 or 3 times as big from the day you switch over. It takes a few days to transition and then the stretch.

So look at how much room you have. Remember you need to keep light a certain distance from plants. And think. If this plant gets 3x bigger will I have enough room?

Good point thank you

Beautiful plants.......well done.
Welcome to RIU.
Like mentioned above........consider that they will at least double in height.

Good looks I gotta flip them soon then

This is a good rule of thumb for all strains right? I'm close to flipping my crop and haven't grown in 10 years so I can't remember exactly how much they continued to grow after the switch. I remember thinking double. Is 3 times common as well?

I would think depends on strain

I always flip my lights nowing it will go 2.5 times taller and sill leave 18 in from the lights. So on mine in. Good to flip at usually 22 inches

Better to be safe than have scorched tops. So it is good to have a factor of safety in there. So that is why I say 2.5-3x. Some plants take longer to transition also. They grow the entire time they transition before then stretching.

If you grow from clones you will know exactly how much on your 2nd flower. But from seed it is hard to tell. Safe better than sorry.

Thanks fellas
