Junior GP6010 Carbon Dioxide CO2 Generator Greenhouse Garden Pad with Humidity Activation for Clone Propagating, 10 Pads

I was unsure how these were going to produce, but they did well. I have done clones before many times with no CO2 additives, these made a big difference in a ten day span. Will use every time from now on.

actually received the bigger pads, but still worked the same.

I use these for young plants. Cut a three liter soda bottle and remove the top quarter. Then put one if these in and turn upside down for a CO2 filled humidity dome. Watch em go!

started using after seeing what bucket did in bloom tent, but I need to use two, be careful fresh taken Clementon close die from eating so much

I used these and found no difference in root development or plant growth. I have (2) 72-cell seed starting trays, both on heat mats dialed to the same temps, under the same lighting, 1 with CO2 Generator sheets and 1 without. Both of my 72-cell trays germinated and grew at the same rate.

I would estimate these increased the amount of roots and shortened rooting time by at least a couple of days.

I didn't see much change after using these pads. I will try it again. In my case, it was possible user error.

The product did not seem to work as claimed. It did not help my seedlings or plants. It was a waste of money..
