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

This is my third one and my second year using them. These things are like cheat codes. Most things I've planted say on the package they will take one week, 3 weeks, etc etc. with these germination stations I found smoke seeds pop within a few days, one week at most!Now, some seeds are harder to germinate than others. I've had a few now that had low germination rates, but I don't think it's due to these germination stations. These are just notoriously difficult plants to germinate, for example Rosemary and passion flowers.Highly recommend these!

This tray and lights worked well for seed starting and early growth. I wish Vivosun included a taller dome for cloning (or at least offered one as an additional option)

Works great, no malfunctions. The heat Matt is my favorite part. I only wish that the dome was a little taller. Great for seedlings, not for clones.

My husband loves this, he’s been using it to start everything for the garden this year

Lights and heating mat are amazing. Germination works great but comes with a cheap plastic lid that was cracked right out of the box. Crack has expanded since first use and now requires tape to hold humidity. Maybe I just got unlucky. 3/5 Stars

The media could not be loaded. 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 = 2.99Intensity 50% = 87 PPFD / DLI = 5.74Intensity 75% = 129 PPFD / DLI = 8.48Intensity 100% = 168 PPFD / DLI = 11.0*PAR (Photosynthetic Active Radiation)*PPFD (Photosynthetic Photon Flux Density)*DLI (Daily Light Integral)In conclusion, Thumbs up!

Piece of junk. I have several Vivo products but this Vivohome was junk. Didn't work out of the box. Called customer service for tech support. Sent pics of problem with detailed information as requested, waited several weeks for response.Offered to refund money. Not send a replacement, no explanation of problem, just here's your money and you can order another one yourself.Would not recommend tjis manufacturer based on their warranty coverage

Honestly unimpressed due to the lights inability to maintain previous settings on power failure. After spending $35 more to get two sets of lights, and then when my other timed lights kick on, these stay off, and i have to manually turn them back on when I see it. Furthermore, if you adjust the brightness, it will also go back to full blast every time you turn them on.I also falsy made the assumption that the lights locked into the lids somehow. They do not. They just casually rest on the lids, which leaves you fighting with them every time you want to open the top. And that is further a problem given how much heat they generate. The heat can be a bonus for germination, and you could maybe get away without a heat mat, it would just he nice if the lights stayed on the lids, preventing the need to touch hot metal.
