stage 2


The vegetative stage is one where the focus switches to green growth. In order to stimulate a plant to grow, propagation plugs are transplanted into larger grow media options. Depending on the style and set up of the operation, some may install plugs into starter or intermediate blocks that are generally small- see our 4″ x 4″ x 4″ starter blocks or 4″x 4″ x 2.5″ starter blocks– while others go directly to larger blocks such as out 6”x 6″x 5.3″ stonewool grow blocks or 6″ x 6″ x 4″ grow block option.

Plants are housed under lighting with more blue light waves to stimulate the vegetative growth. Plants are then given fertilizers higher in nitrogen to stimulate more growth and healthy root development.

As the plants are small, they can be housed in smaller block sizes and placed closely together to save space.  Once roots pop out of the bottom or plants reach their desired size they can move to bloom/flower stage.
