Spider Farmer SF1000
#7 in Under 300 WFull review
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.

2.2/5
A simple, silent white panel for a shelf of seedlings or herbs. Hard to justify on price against the cheaper dimmable panels here.

Mars Hydro TS1000
#8 in Under 300 WFull review
A cheap, simple panel for a 2x2 ft tent. Good for a first grow, though a bar light of the same wattage gives noticeably more light.

Mars Hydro TS600
#9 in Under 300 WFull review
A cheap starter panel for seedlings, microgreens or a few herbs. Spend a little more on a bar light for anything that fruits.
