I purchased 10 seeds from Nirvana. I decided to go with Northern Lights and Blackjack. I purchased 5 fem seeds of each strain. I wasnt able to get any info from the net on how to germinate seeds using rapid rooters. Some people said they tried or used and it was a success or not, but no one saying how they did it. I found some info on how to germinate in a shot glass with water then transfer to soil, but I grow with a hydro top drip setup. And I place my clone cuttings in rapid rooters. So I decided to use the shot glass method and then try my own rapid rooter method. I just checked my seeds after placing them in the rr's and discovered I have 10 of 10 showing the tap root and a few already breaking the surface and begining to thrive! So let me give my info so you can do the same. I am a novice grower but have been reading and attending classes and have really became knowledgable as of late. Lets begin... I received my seeds, I then filled 10 shot glasses with tap water, I am in portland OR so we have clean tap water, people say to let it sit for 24 hours, I had a bucket of water sitting out for 10 hours that I was saving for my hydro veg room, so I took the water from here and put it in the shots. I labeled my shot glasses with a piece of tape for the 5 BJ seeds, and left the NL seed glasses blank. I then placed my seeds into the glasses and let them sit in a shoe box in my office at 70 degrees for a day. This is intended to let the seeds get wet and fill with water. You know they are full when then sink to the bottom, because at first they will float. My seeds however didnt sink on their own, so I decided to stir and tap them, to my surprise most of them fell to the bottom of the glass and stayed. So I figured they were done. The others did this after a few more hours. From here I took my rapid rooters and dunked them into my water bucket, the same water as I filled the shots with. I squeezed the rapids a bit to get excess water out, these things as I have found, hold water and stay moist. You dont need them dripping wet. On half of the rr's, I placed the seeds in the top hole and pulled a piece of rr from the bottom and stuck it in the whole to cover the seed. For the other half of the seeds I cut a slit in the bottom of the rr midway on the bottom, and halfway down the side so I could place the seed in this slit. Like I said, im no expert and I couldnt find any info on people using rr's and how they did it. So this was an experiment. come to find out both methods worked the same. I put the seed filled rr's into a small basket i got at the hydro shop and placed them in a tuperware container w/ a lid. I sprayed the inside of the container with water and sprayed over the top of the rr's with this water too. I had a small plastic straw that I put between the container lid and the top of the container to allow air to flow in. I set the container in my dark closet for 2 days. I checked them today and tap roots were out on all seeds, and some seeds were starting to rise to the top of the RR. non having punched through the top just yet. I then moved my baskets with the rr's from the container into my clone tray with the dome lid that I place under my 2 24'' t5 grow lights. Pictures are below. I will update as to how long and if this continues to work. So far so good! I am very excited and this has been very easy! I hope people can use this info to help them. Having read other threads on here that have helped me I thought it was only right to share what I have learned and has worked for me. More to come.... Enjoy! Pics... The rr with the plant showing is a clone cutting I have, and the rr with the white on the top is the first of the seeds coming to the top!
