Growing with T5 lights

A question from a fellow grower:

can you grow a pound with T5 lights I was thinking of buying a 4 foot or 6 foot T5

I doubt it. T6 is great for seedlings and veg cycles. If you wanted to grow a LB. with T5’s, you would need several in order to surround the plant. a 6’ ebb and flow using LST method might get you a better yield but, with just one 6’ T5, you are not going to have the necessary light intensity to grow a LB. In general.

The only time I ever got a LB from a plant indoors was using a 1000w HPS HID w hortilux bulb/lamp
