Spider Farmer SF2000
#5 in Under 300 WFull review
A quiet single panel for a 2x4 ft tent or a seedling shelf. Choose it for its simple build; a bar light gives more light for the money.

4.1/5
A light, quiet panel for a 2x2 ft tent of seedlings, herbs or leafy greens. Good value for a first grow, though bar lights use less power for the same light.

A low cost, quiet panel for seed starting, herbs and a small 2x2 ft tent. Pick a bar light instead if you want the most light per watt.
