New indoor grower Hey ive been growing outdoors for a long time now but due to green harvest being alot more strict i had to move everything inside, well i just started germinating another batch, my question is can i veg the plants outside and then flower them under a hps light indoors? also if i have 15 10" pots side by side 3x5 how big of a light do i need? can i get away with a 400w or should i get a 600w or a 1000w?
