Newbie here, first grow. My ladies have reached around 13-14inches each. Too soon to switch to flowering or good to go? ![image](https://global.discourse-cdn.com/growingmarijuana/original/3X/9/5/954dc83400b1f088fa7064c94706a0b01613efdc.jpeg) ![image](https://global.discourse-cdn.com/growingmarijuana/original/3X/9/c/9cd51e498ef9c5289362ea4c4ffd456fed78f2f3.jpeg) ![image](https://global.discourse-cdn.com/growingmarijuana/original/3X/d/e/de3f2789690041bb209efb3fb6a5f53b8832a77f.jpeg) ---

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

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. ---

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. ---

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. ---

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. ---

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

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? ---

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
