Glowing PyroDinos with DinoNutrients - Grow Bioluminescent Plankton

I was a little skeptical at how bright these were going to be, But they are really amazing! They were dimmer the first few days, but as you can see in the video they brightened up quite a bit after about a week. They are easy to take care of. They need sunlight, a bit of oxygen, and the nutrient. They sit in the sun of a frosted window, I stir them every few days for oxygen, and I leave the corks undone unless I stir them to show them off. Other than that I've just been giving them a drip of the nutrient every 2 weeks. Great gift idea for budding scientists or friends who love nature. I'm going to put some in different sea creature shaped glass bottles and give them as gifts.

This was such a disappointment. Either this did not ship fast enough and all the phytoplankton died or I was scammed into buying expensive water. I used a grow light on a timer, following all the directions, but have been unable to see any glow or signs of any sort of life(or death). I have waited a couple of months to submit a review hoping to see some type of growth, but no glow, no film in the water to show die off, nothing. Don't waist your money, skip purchasing anything from this company. It's a scam. Zero stars.

They are alive and thriving so far! When I first got them I took them out of the box immediately and put them in the sun, waited till night and they glowed perfectly. If you’re considering getting these, remember they’re alive and can’t sit in a box forever. I’ve had them for more than a month now and they seem to be doing well. I’m very happy with them.

Love this!! They’re so fun!!! Mine stayed alive for a long time until I accidentally killed them on my move): but I truly loved this and how pretty the glow is!!!(well, was hahah)

This is actually the third batch I bought from PyroFarm, yet the first time I tried on Amazon because I wanted free shipment for an unboxing video. Both batches I got directly from their website travelled all the way from California to Atlanta, was healthy and are still thriving in my living room. However, this one I got through Amazon looked fractured (I mean the cells not the pouch) when I opened it as soon as I received the package, and as many reviews here says, did not glow that night. I don't know how Amazon handled these delicate fairies, maybe it took too long for the logistics or suffered from recent heat wave, but the ones I got directly from PyroFarm website a few days ago definitly glowed on the day they arrived. On website, they deploy a very strict shipping schedule to make sure the algae spending minimal time in complete darkness and unstable temperature. So I would advice you to NOT buy the living part through Amazon. Other accessories should be fine, in my opinion.

There was a problem with the order shipping that led to the expiration of my order. I left a message after I was sure of the expiration to let them know and I paid for another batch. It was not their fault. The great ones of PyroFarms promptly responded and told me that they were sending more. Excellent example of "The Golden Rule". Bravo! Thank you PyroFarms for renewing my faith in humanity! These are absolutely magical! I plan to keep and grow them for the rest of my life! Thank you PyroFarns for this little being of Paradise! - Dwayne Archer

Will update review but as of right now not really worth my Dino’s are not really glowing in the dark :/ not sure if I did something wrong but since obtained package they haven’t glowed very bright

Arrived alive, super glowy. Would buy from them again

It's totally entrancing to see the flashes of blue green light when I shake the culture vessel in the dark of night. The culture arrives with extra food (medium) and good instructions.

Followed instructions and unfortunately I have not seen any change. I bought this around Christmas time. I would like a refund.
