bought in 2016, still works even with the Yellow cover, sun damage makes the plastic brittle, will be ordering a new 60, maybe a thicker cover or one of the new plastic material. something to think about, but 4 years of used, not bad. I give it 4 stars only because of the plastic cover, they are cracking now, the other parts of the Dome is holding up fine. thank for having this product

I bought my 40-cell biodome because of the height of the top, but feeling a little skeptical about the build-up of it. After all, it was just a place to start my seeds, right? Well, when I received my new biodome two days ago, was I ever surprised and impressed!!! The packaging was fantastic and my biodome arrived in perfect condition, as did the seeds I'd ordered along with it. I planted cosmos and poppies, thinking that I wouldn't see any sprouts for at least a week. Well, not even 48 hours after planting my seeds in my new biodome, I've got flowers sprouting in my kitchen! And, here in Northern Michigan just days before Christmas, that's saying something!!!!! I'm getting a grow lamp this week so I can grow my flowers indoors, and when other people are thinking about planting their seeds to set outdoors, I'll be enjoying blooming cosmos and poppies in my den, all thanks to this wonderful biodome! I just wish it came large enough to attach to my house so I could have a full-sized greenhouse!

Do the seed grow? Yes. But after years using the large cells, I kept finding that unless you break them apart (and risk damaging the roots) the large sponges will stay intact on the ground for years, long after the plants are compost. I have tried them with all kinds of vegetable from artichokes to zucchini and it's always the same. Why did I use them for years? The domes are a large investments (mostly because of the price of the sponges). Now, I roll some pieces of paper towel or newspaper, insert them in the holes and fill them with soil. The smaller sizes some times will break apart, but being that I'm into organics finding sponges intact makes me question exactly what they are made off.

This thing is working like a charm. So confident and easy. Will be ordering more sponges. Maybe another dome as well.

Bought three total so I could grow my own transplants and was very excited with my success. Grew tomatoes, chard, lettuce, onions(60 cell dome), and an assortment of herbs. My germination rate was unreal! Very easy to grow and very easy to transplant-strong and vigorous plants. Follow the directions and enjoy.
