# VEVOR Four vs Six-Tier Grow Shelves: Which Fits? > Compare two VEVOR grow shelves by footprint, light bars, height, and timer controls. Choose for your trays and space before buying a larger indoor setup. Canonical: https://mizaanhome.com/en-us/guides/vevor-four-vs-six-tier-grow-shelves/ Last updated: 2026-09-28 **Verdict:** Choose the four-tier VEVOR for a shorter setup with three light bars. Choose the six-tier version when you need five bars and a mechanical timer in the same floor footprint. Count the trays you actually plan to light before paying for extra levels. --- We may earn a commission from our links; this guide is based on published information, not hands-on testing. The **four-tier VEVOR grow shelf** suits a smaller tray setup or a lower space. The **six-tier version** adds two light bars and a mechanical timer without taking more floor space. Choose by the trays you need to illuminate: these racks have three and five lights respectively, so shelf count alone overstates the number of separately lighted levels. ## Start with the trays you will use Lay out your intended seed trays before ordering a rack. Measure their outer rims, any catch trays, and the height of the domes you use. Both VEVOR models have nominal 35.4 x 13.8-inch shelves; that is a starting dimension, not a promise that a particular tray combination will fit between the uprights and raised edges. A small batch may need only one suitable light over an existing surface. That can be a simpler purchase than a full rack. University of Maryland's [seed-starting guidance](https://extension.umd.edu/resource/starting-vegetable-seeds-indoors) describes an indoor setup around containers, growing medium, light, and crop timing. Buy more levels when your sowing plan calls for them, rather than filling a rack because it has room. Think about the outdoor destination too. The [raised-bed choosing guide](/en-us/guides/how-to-choose-a-raised-garden-bed/) helps size the planting space that these seedlings will eventually need. A large indoor batch is less useful if the bed or patio containers cannot accommodate it. ## What the extra height and lights change Both racks occupy 35.43 x 13.78 inches on the floor. The four-tier model stands 59.06 inches tall; the six-tier model reaches 70.87 inches. Mark that height on a wall and check whether you can comfortably inspect, water, and lift trays from the levels you plan to use. Allow room in front for removing them. The four-tier rack includes three 30 W bars, each 24.02 inches long. The six-tier rack includes five 30 W bars, each 34.53 inches long. The longer bars extend farther along the shelves, but their length does not tell you the intensity at each plant or establish even coverage at the edges. Adjustable shelf positions help you make room for taller seedlings or pots. Leaving a larger gap for one plant reduces the vertical room available elsewhere. Neither model turns its full height into usable plant clearance once lights, shelves, trays, and plant growth share that space. ## Controls and light requirements The smaller rack offers three color modes with independent switches. The larger has a mechanical timer dial, useful when you want daily switching handled automatically. Color choice and timing serve different purposes: a timer controls duration, while a color-mode label does not establish the amount of useful light reaching a plant. University of Minnesota's [indoor plant lighting guide](https://extension.umn.edu/garden-and-home/yard-and-garden/gardening-in-minnesota/lighting-for-indoor-plants) explains why plant needs, light intensity, distance, and duration matter together. Use crop guidance and the supplied light instructions to set up your growing area. There is no single distance or daily lighting period that fits every seedling, herb, and mature houseplant. The listed totals are 90 W for the four-tier model and 150 W for the six-tier model. Those figures describe the supplied lights' power, not a measured growing result. Choose the additional lights because you need more illuminated positions, not because the higher wattage promises a larger harvest. ## Space, water, and the next stage of growing Both models have swivel rubber casters. Plan their working position around access to the trays and the supplied cords; wheels do not establish a safe loaded-moving capacity. Follow the supplied instructions for assembly, loading, and repositioning. Keep watering separate from electrical connections. Catch trays do not make the lights, plugs, or shelf assembly waterproof. Choose a location where you can tend the plants without splashing the connections or putting the rack in a circulation path. If the real goal is growing a few plants outside rather than starting multiple indoor trays, compare [raised beds and grow bags](/en-us/blog/raised-beds-vs-grow-bags/) before committing space to a rack. The [gardening hub](/en-us/gardening/) brings together those outdoor options and this indoor comparison. ## Purchase terms to check The card prices are the VEVOR item prices checked in September 2026, before tax and destination-specific charges. Confirm your delivery address and total at checkout; remote-area charges and heavy-item timelines can differ from a standard shipment. VEVOR's general return window is 30 days in original condition with prior authorization, and its standard warranty is 12 months, subject to its terms. Change-of-mind returns can involve return-shipping costs. Measure your trays and available height before assembly so a sizing mistake does not become a return-shipping expense. ## Sources We compared VEVOR's exact-model specifications and purchase terms, checked September 28, 2026, with university growing guidance; we haven't tested these shelves. - VEVOR 4C15090-2020T06P3-US and 6C18090-T8DP09P5-US product pages, reached through the card buttons: dedicated specifications, controls, dimensions, prices, and availability.
