    Last year I bought several of these. The seedlings came in somewhat tall and stringy, but it's entirely likely that I'd spread the light out among too many things, had them too high up, and didn't have them on long enough (I can't recall how long exactly, but very likely not more than 12 hours).

    So, this year I have three of them focused on a 10x20 seedling tray, about 7-8" above it (which is as close as I can get while using one of those clear plastic "greenhouse" hoods). They're on a timer for 14 hours (6 AM to 8 PM); the setup is in a basement, so there isn't significant sunlight getting in. I have the bulbs in those basic utility clamp-light setups you get at Home Depot; I removed the fixtures' reflectors, since the bulbs already project their light downwards and this enabled me to group the lights very close together so I could focus all three on the tray.

    So... the question. Any way to know if these bulbs are actually any good? The reviews were excellent, but then again a) there could be a bunch of biased reviews (from the manufacturer or seller, or from people "encouraged" to give reviews in exchange for stuff), and b) they could be simply uninformed and not realizing they're getting subpar results.

    My seedlings now range up to 2, nearly 3 inches (different plants, seeded different times, so different results) and if I need to enhance the lighting I should do so now.
