VIVOSUN6-Pack Seed Starter Trays, 240-Cell Seed Starter Kit with 2 Set of LED Lights, 3.6" Higher Cover, Adjustable Vents, Drainage Holes, Green Propagation Tray for Planting Seed, 40 Cells x 6 Packs

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!

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.

Pros:-Lots of cells for seedlings-tall humidity dome so seedlings can grow-retains moisture well-little slots on dome for lights-good germination rate with the lights-lots of supplies for the price, decent bundleCons:-not very sturdy, especially the cells. The plastic is thin and crinkly. i won’t be able to reuse the cells more than once or twice.-flimsy cells makes it hard to bottom water as that tray bends a lot with the weight of the soil and water-lights not great past germination stage, my seedlings ended up thin and spindly

I purchased this to streamline the process and it has done just that. I’m able to place rock wool or soul directly into the tray. The dome with vents is great and I’m able to control the humidity within fairly easily. The leds fit securely into the lid and have adjustable power and timers for all cycles. The heating pad works great! Makes it super easy to keep the unit at a constant temp. It’s a bit flimsy as far as the plastic but that’s pretty much expected. Easy to clean up and start a new round. I’d definitely recommend this!

Great seed starting trays that should be useable for several seasons if taken proper care of. This is my second season using these trays and so far they have held up very well.

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

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.

absolutely terrible. took a chance and it showed up with the plastic dome cracked all over. Should have read all the reviews they all say the same thing this dome shows up cracked. waste of money and time
