Then, Can I use t8 bulbs to grow plants?

With the help of T8 fluorescent lights, you can have fresh vegetables year-round. You will need to use four fluorescent tubes, however, to provide enough light for these sun-loving plants to thrive on a covered patio or indoors.

Considering this, Which is better t8 or t5? T5 HO lamps have a much higher lumen output than T8 lamps with the same tube length. In most cases a 2-lamp T5 HO fixture produces more light than a three-lamp T8 fixture. T5 lamps have a higher optimal performance temperature than T8 lamps (95°F vs 77°F).
