Best LED grow lights for indoor plants

Start here: MARS HYDRO TS1000. A full-spectrum panel with real intensity behind it — the one to buy if you want plants to actually grow, not just survive a dark corner. It's the closest thing here to a proper grow light at a beginner's outlay.

Who the others suit:

• Spider Farmer SF4000 — for a dedicated grow tent or a whole shelf of fruiting plants; far more light than houseplants need.
• SANSI 40W clip-on — for a few pots on a windowsill or desk; the clamp and timer make it easy.
• Vita Grow Light — for a single plant on a shelf, with the best owner ratings of the bunch.
• Mosthink strips / Great Value 2 ft bar — for lining a shelf or cabinet cheaply.
• Lordem / ACKE / Gaormii — small desk lights for low-light plants and seedlings; fine for supplementary light, not for heavy feeders.

Rule of thumb: match the light to the area, and keep it close to the leaves.
