Nope.

I dunno what those are designed for. Displaying plants, maybe. Sure not for growing.

Wider lamp spacing maximizes light distribution.
Yep. Also minimizes intensity. 2-4 foot shoplights from HomeDepot will give you better results, just cause the spacing's better. They don't even tell ya what type or color these tubes are. At 20/40watts, they're prolly the obsolete t-12's.


But are these vegging color, or bloom color? (moot point, these won't work for bloom because of that dumbass wide spacing.)

4 foot lamps give you more than double the light of 2 footers. Often the 4 footers are cheaper, too, cause they're more common.

The only reason to use 2 footers is if that's all that'll fit. (IMO)

All you need for vegging is some 5500-6500K fluoros. Bloom is something else. Need more power. HTH, Hermie
