Buying Guide

Match fixture length to bench or shelf

Measure your mini greenhouse benches and choose 2–4 ft fixtures so light covers plants evenly without gaps or overlap

Prefer full‑spectrum LEDs for round‑the‑clock growth

Full‑spectrum LEDs and T8 full‑spectrum tubes deliver broad light similar to daylight, supporting veg and bloom stages in compact setups

Evaluate watts and watt-equivalent output

Compare actual wattage and listed lumen or PAR values to estimate how much usable light a fixture provides for your plant density

Consider fixture shape and reflectors

V‑shape reflectors or flat LED strips affect light spread; choose reflectors for focused rows or flat strips for wider coverage in shallow beds

Factor cost per fixture and pack sizes

Buying 2–4‑pack fixtures can lower per‑unit cost for uniform coverage, so balance upfront spend against how many fixtures your greenhouse needs
