t-5 t-8 and t-12 Lighting Discussion

[drudown11]

Drudown11 - I am confused by your remark back... LOL. Could you elaborate on this statement?

they light that the t5 emits is only intense enough 2-6 inches from the bulbs. Theyre good for small plants and clones that are under a foot tall, but they light doesn't penetrate more than a foot. You really have to keep them huddled next to the bulb to get good growth, otherwise you get stretchy and scraggly branches. If you want to flower a plant, a hps bulb(also known as a High intensity discharge bulb, HID for short) will give more more yield and will illuminate the plant more than a t5 fixture will.


The light from MH and HPS will penetrate all the way to the bottom of the plant if placed correctly. T5 only reach about half way down.
