adding new plants to grow room

is it all right to add plants ant different ages to grow room. if i have 6 plants thats been in flowering can i put another 6 from my veg room and start them to flower with the 1 month plants?

i guess its okay just remember to get rid of males

yes, build a stand of some sort so you can get the new ones close to the light still even though your plants are of different heights.
