VIVOSUN 1-Pack 40-Cell Seed Starter Trays with 1 Set of LED Lights and 10"x20.75" Seedling Heat Mat, 3.6" Higher Cover, Adjustable Vents, Drainage Holes, Green Propagation Tray for Planting Seeds

Impressive starter kit. Fit and finish are very good. The price is competitive with other brands, however the durability is questionable. The plastics are on the thin side. However, sturdy because it is square shape. The longevity depends on how one respects their belongings. All settings and accessories function per the description. The heating mat temperature and the thermostat control are relatively accurate (+/- 1° f). The built in timer is optional to use and changes colors depending on the schedule (Off, 8/16, 12/12, 18/6). The selector switch provides feedback with a solid feel and loud click sound so you definitely know you pressed the selector button. So does the entire household. The light intensity settings and timer settings have memory as long as it is connected to a power source. Unplug the power cord and all settings are lost. An external timer is a no go. A power outage will definitely be inconvenient. The light panels lay nicely snug in their designated position. Nothing to secure them in place. Use slight care when removing the lid. Perhaps secure the light panels with painters tape (less adhesive) for easy removal. Test time… The readings will fluctuate by a couple numbers depending on the ambient lighting. I tested the lights in a well lit living room; artificial lighting/natural ambient lighting from windows. I tested the PPFD (umol/m2/s) and DLI with the Photone Pro app with their optional (recommended) diffuser. The phone with diffuser was then placed on top of the seed tray. Sprout level. PAR setting is on Full Spectrum lighting. READINGS: Light intensity = PPFD / DLI (18 hours of light). Intensity 25% = 46 PPFD / DLI = 2.99 Intensity 50% = 87 PPFD / DLI = 5.74 Intensity 75% = 129 PPFD / DLI = 8.48 Intensity 100% = 168 PPFD / DLI = 11.0 *PAR (Photosynthetic Active Radiation) *PPFD (Photosynthetic Photon Flux Density) *DLI (Daily Light Integral) In conclusion, Thumbs up!

Great item!! I had one problem tho my lid arrived broken and I got ahold of support and they helped me work out everything really easy and fast

The VIVOSUN 1-Pack 40-Cell Seed Starter Trays with LED Lights and Seedling Heat Mat is a comprehensive setup for starting seeds and promoting healthy growth. The kit includes adjustable vents, drainage holes, and a higher cover, all of which are beneficial for successful seed propagation. However, upon receiving the product, I found that the size of the seed starter trays was slightly smaller than I had anticipated. While the functionality and features of the kit are impressive, the smaller dimensions were a bit unexpected based on my initial expectations. Despite the size discrepancy, I have found the VIVOSUN seed starter kit to be effective in nurturing seedlings and providing the necessary conditions for germination. The LED lights and heat mat have been working well to support plant growth, and the overall design of the trays is convenient for seed starting. In conclusion, while the size was not as large as I had imagined, the VIVOSUN seed starter kit has proven to be a valuable tool for my gardening endeavors. I would recommend it to others looking for a reliable and well-equipped seed propagation system.

Great way to start seeds! I love this seed starter, it function well and the build quality is great. The heating mat doesn't work as well as my Vivosun heating without the thermostat but it is what it is. The design is good except for no real way to secure the lights from moving around other than that I love this thing. Definitely a good buy, could be a bit cheaper.

Worked well. Good product.

The dome is too low and the receptacle bottom part is too thin and would break easy. However, the lights in the heating mat are top-notch..

This thing is the bomb. Plant growth and germination have no choice for those warmer weather plants. It seems very sturdy and the lights are pretty bright. The light has a timer which is great and it even comes with a heating pad. It’s super easy to set up and also fun! Me and my kids loved it. We will see how it does as we just put all the soil and seeds in.

These are awesome and I will be ordering more. With 2 sets of lights for multiple running systems, you can't beat it.

Fantastic for starting garden. Ive bought multiple of these and they are great. The base trays i use for bottom watering year round, and the light with seedling starters have been instrumental in getting garden going.

Es un kit demasiado útil,me ayudo a tener a las plantulas en un ambiente óptimo para su fase, ahorrando espacio en la carpa de cultivo y asegurar la germinación, además por el precio es una increíble opción, un tapete termico el cual es muy útil para germinar o enraizar esquejes en invierno y un par de luces muy potentes para el tamaño y el costo (yo las uso al máximo de intensidad incluso los primeros días de germinacion el domo ayuda a que no reciban exceso de luz) las plantulas se desarrollan a muy buen ritmo con estas luces, el tapete termico además cuenta con un termostato que se agradece ya que e visto algunos que solo se conectan y estos calientan tanto como los dejes contestado y a cierta temperatura, este ayuda a tener una temperatura justa y no tener que estar al pendiente de excedente con el calor o que las plantas pasen frío. Honestamente me sorprendió lo útil que me resulto este kit ya que me ahorra mucho espacio y puedo tener a las plantulas creciendo a buen ritmo, por el precio me parece una increíble opción en especial por la autonomía de sus componentes(las luces incluyen timer y su tapete incluye termostato), el platico no es muy grueso pero tampoco es barato ni delicado, la mia llego un poco doblada de una esquina pero nada estético ni que afecte, es muy útil, de bastante buena calidad, te ayuda a controlar de mejor manera la etala de germinacion, platula o enraizamiento, además barato así que no creo que te arrepientas de comprarlo .

helps me get my seedlings started before transplanting into 1gal and moved to my grow tents

Works great. Just wish it would show the actual temperature.

Ich war auf der Suche nach einer unkomplizierten Möglichkeit, meine Keimrate bei verschiedenen Pflanzen zu verbessern – und dieses VIVOSUN-Set hat meine Erwartungen übertroffen! Das Mini-Gewächshaus ist stabil, durchdacht und in Kombination mit der Heizmatte ein echtes Power-Duo. Besonders gefällt mir der integrierte Thermostat: Damit lässt sich die Bodentemperatur präzise einstellen – perfekt für empfindliche Samen oder kühle Räume. Die Abdeckung hält die Feuchtigkeit optimal und sorgt für ein ideales Mikroklima. ✅ Vorteile: • Hohe Keimrate dank konstanter Wärme • Thermostat ist einfach zu bedienen • Alles sofort einsatzbereit – keine Bastelarbeit nötig • Perfekt auch für Anfänger ❌ Kleines Manko: Das Plastik der Haube könnte etwas stabiler sein – bei vorsichtigem Umgang aber kein Problem. Fazit: Sehr empfehlenswertes Starter-Set – ideal für Gemüse, Kräuter oder Stecklinge. Mit diesem Set klappt’s mit dem grünen Daumen!
