When to switch from Veg to Flower


#1

Newbie here, first grow. My ladies have reached around 13-14inches each. Too soon to switch to flowering or good to go?


#2

How many weeks have they been in veg? Auto or photo?


#3

They still look a little small to put in flower. How old are they? You can start flower anytime after about four weeks of veg.


#4

Look at the available room in your grow space including light distance and target your plant height for 25% below that number. That should maximize the space and give you the best yield.


#5

We’re at 4 1/2 weeks of veg. Odd as it may seem, I don’t want them TOO large as I’m concerned about smell. Grow setup is room over garage, the entire room (fairly large so I don’t have a ventilation system set up). The temp Has remained a constant between 72-75 and humidity 33-40. These are not auto flower.


#6

Gotcha, they can certainly go into flower now if you want small plants, but they’re still going to smell. They always smell, so you might want to set up a carbon filter and fan to help with that.


#7

Limiting the size of the plants won’t do much for odor IMO. A carbon filter and negative airflow is what you need.


#8

Well let me ask you this…I switched to 12 darkness this morning, if I switch back to the veg cycle am I screwing my self?


#9

No, you should be just fine. That’s not enough time to cause them any difficulty.

Man you can put them into flower when ever you like
