A ready-made stand is the better buy if you want seedlings under light this weekend and have nowhere obvious to hang strips. Strips on existing shelving deliver more light per pound and can be doubled up where a crop needs it, but you are buying hangers, a timer and a socket strip too. The trap with stands is wattage: the cheap ones are fine for germination and too weak to hold transplants.

Both approaches end in the same place: trays of seedlings a few inches under light for fourteen to sixteen hours a day. The difference is how much assembly and specification work you do yourself, and how much light you end up with.

Wattage per tier is the number to check
Stands are sold on tier count and rarely on light output, which is where the disappointment comes from. A FREELICHT 5-Tier Plant Stand with Grow Lights, 4 x 10 W ($69.99) at 10 W per tier will germinate seed and hold a seedling through its first true leaves. It will not hold a tomato transplant for six weeks without stretching.
A FREELICHT 5-Tier Plant Stand with Grow Lights, 4 x 30 W ($118.99) at 30 W per tier is a different proposition and covers the whole propagation period for most crops. The price difference between the two is small relative to a season of leggy seedlings.
What the strip route actually costs
People compare a stand price against a strip price and conclude strips are far cheaper. The honest comparison adds the shelving, OneChoi Adjustable Rope Light Hangers, 8 ft ($35.00) to hang the strips at adjustable height, a timer such as a BN-LINK 7-Day Programmable Digital Timer Outlet ($13.99), and a socket strip. If you already own the shelving, strips still win comfortably. If you do not, the gap narrows.
What strips buy you that a stand cannot is the ability to change your mind. Two Barrina T8 2 ft Grow Lights, 5000 K, 6-Pack ($71.24) sets across a shelf give double the light over the tray that needs it, and none over the shelf holding a crop that does not.
Note
A timer is not optional either way
Manual switching produces an inconsistent photoperiod, which shows up as uneven growth, and it eventually produces a forgotten fourteen hour night. A cheap seven-day digital timer costs less than one tray of seed and removes the whole problem.
The decision, summarised
No shelving, no time, wants seedlings under light now: a stand, at the higher wattage.
Already owns wire shelving: strips, hangers and a timer, and it will cost less and light better.
Germination only, potting on elsewhere: the low-wattage stand is honestly sufficient.
Holding transplants for weeks before planting out: 30 W per tier or better, or doubled strips.
Growing several crops with different light needs on one rack: strips, because you can vary shelf by shelf.
Both routes, priced
The two stand wattages, and the parts that make the strip route work.
Wattage is a poor proxy because efficiency varies, but as a rough guide around 20 to 30 W of modern LED per square foot of tray, hung a few inches above the canopy, suits seedlings. The number worth targeting is PPFD at leaf level rather than watts at the wall, and the DLI calculator converts an intensity and a run time into the daily total the crop needs.
+- Can I use ordinary LED shop lights instead of grow lights?
Full-spectrum white LED shop lights at around 4000 to 5000 K grow seedlings perfectly well, and many products marketed as grow lights are the same hardware with different packaging. What matters is output and how close you can hang it. Avoid very low output strips sold on colour rather than on watts.
+- Do I need to raise the lights as plants grow?
Yes, and this is where fixed-shelf stands lose out. Light intensity drops sharply with distance, so a fixture that was correct over a freshly sown tray is too far away three weeks later. Rope hangers make this a ten second job. On a stand you are limited to the shelf positions the frame offers.
+- Should the lights be on a timer in a greenhouse with daylight?
Yes. Supplementary light is usually run either side of daylight to extend the day to a consistent length, and a timer is the only practical way to do that. In late winter, when natural light is both short and weak, running lights through the middle of the day as well is often worthwhile on dull weeks.
