Can i put two autos in one 5 gallon pot?

I agree with @shaw076 - good feedback from him

if your tight on space i'd put them in 3 gal pots. autos don't generally get that large due to the short veg time anyway

you can do whatever you want .. however i wouldn't. your likely to root bound both plants overcrowding like that .one would likely overtake the other stunting its growth, just not a good idea in general
