Lighting

Im currently using a 20 W florecent daylight bulb that is supposed to be suable for growing. Is this going to be strong enogh



''''

no... you will need more light than this for proper veg and flower.

edit
a good rule of thumb is 50 watts per sq foot of space.

i dont really have to option to go any bigger than this, it seems to be working alright right now but the plants arnt getting as big and busy....im guessing the end restult will be what i thought in the first place..... inexpensive gear= smaller yeild
