NEWBI Can I Get a OZ per plant with what i have?PIC

You can easily use the 1 gallon pots have produce a oz, i would go to 3 gallon before i go to 5. 5's are so much bigger, and i havent seen much of difference in 5 than 3..and u can fit more in the room with 3s
you can mix any kinda soil together and chances are its going to work..and if your using mg's soil..i like moisture controled one the best

i have seen ounce plants come out of the soil ....black gold , also have seen one of my plants actually do 2 ounces in fox farms mix of mostly ocean forest with some coir in it ...about 1/6 coir maybe ...

im testing one of my honey-b strains in a 5galllon pot to see
what happens, all my others are in a 2litter or 1gal pot

ITS THE ONE ON RIGHT:

what i do diff tho for sure is i work em up .....like i let em get big in smaller pot and upgrade a couple times ....i have always had faster growth that way .....i only grew out in soil a couple times tho ...usually do a mix of soil and coir ..and water with plain water ...then finally they get transplanted to pure coir and i just start bloomin em in ebb and flo tables

as long as the roots are spaced properly the pot size is not an issue for yeild its basicly the light intensity at positioned angels(at bud sites)
