T8 lights for growing cannabis

Growers recommend using this light in spaces that measure 3’x3’ or more. The reflector itself is 19” x 19” x 5”.

While fluorescent lighting may work for small-time growers with a handful of plants, you will need to invest in an upgrade if you’re wanting to produce more marijuana. LEDs and HIDs are much better for getting a higher yield.

Hydrofarm is back again with the Fluorowing Compact Fluorescent System. This model is designed for a small grow space of 2’ x 2’, with 125-watt bulbs. You will need to add additional reflective sheets for maximum efficacy, but this light is still decent for small spaces.

What are the benefits? …

With an 8ft power cord, this model also has the advantage of being water safe. The Durolux model should remain safe in damp conditions. Plus, there is an AAG Stucchi lampholder that prevents fire if the tubes become loose.

You can buy this product in multiple versions. First off, you can choose between 2ft or 4ft lights. Then, you can decide whether you want two, four, or eight tubes. The EnviroGro bulbs have a sturdy, reliable construction and come pre-assembled. All you need to do is plug it in.

Although this model doesn’t offer vertical positioning like the EnviroGro FLT24, it does offer two modes of light. Switching off some of the tubes allows for dimmer light that works better for times when you need it a little darker.

There are two types of fluorescent lights: CFLs and T5. A CFL bulb has a twisted, coil-like shape, whereas T5s come in straight tubes.

I’ve never grown with T8. As you’ve said, the common information is that they aren’t suitable for growing. Have you tried T5HO or those Cree LED "lightbulbs" from Home Depot? (<<link) I’ve used both and they’re great. It would be interesting to hear how T8 compares to those alternatives.


T8 works just fine for veg. Still the best option for a low priced veg startup at 10 dollars a 4ft shoplight.


You can grow under a 75 w light bulb lol
but the question you must ask your self
