Question why are they growing slow

Hey i need a little help. I am in my 3rd week of growing. They are growing sssoooo slow. How can i speed them up? I am growing Indica and the unknown plant look like a Sativa

You don't have strong enough lighting.

well i went out and got 3 plant grow lights from wal-mart and it did speed it up a little, hell faster then CFL lights i was using. Are there any other ways to speed them up?

did i miss the pics? either way, allowing them to dry a bit will better allow them to breath and grow fast, imo. what type of light is the 'grow light' from walmart?

are the plant lights florescent???

yes they are plant light florescent, and they do work better then the ones i was using the light looks purple. Maybe i should have use these lights when i 1st started. I am only using the plant light for the veg stage. i have the 400w HPS for the flowering stage

Temps, Ph of water, lights etc... are all keys to the success of the grow

need more information.
