But as I said I'd be happy to do some for your for passing along the word for me. I'm gonna hit some hydro stores but man the gas just to drive to the valley is killing me. Thanks again for your input fdd. Hope to hear from you soon.

Tissue sample about the size of a pinky nail is plenty. The younger the tissue the better. Like I said I tested cotyledon's or the first leaf on my plants. But I waited until they had one set of true leafs before I took them.

FYI I did this for myself. 31 seedlings took less than 24hrs for me to do myself. But I obviously wouldn't want to commit to such a short turn around. I would feel comfortable saying 3-7days. Cut my plants down to 18 females. Kept a few males for breeding but segregated them out...

Excellent suggestion! That is likely the way I will do it.

I'd do some analysis for you for half price if it would help me spread the word. Or maybe just a few test plants if you want to try it.

I can't confirm this 100% but hermaphrodites would likely score positive as being male in this assay.

Well I actually have all the raw material I need at this point to do alot of analysis. All that is required is my time. If I run out of my ability to get the raw material the cost could go up somewhat but not apprecialby if the volume is substantial.

Okay to answer your questions. Takes 24-48 to do the test. Yes I can do literally 96 samples at a time. Most time is in isolating the DNA from the plants. I would say 24hrs to get the DNA(if there are a large number of plants) 4hrs to run the genetic screening.

As long as there is genuine interest. I"ll work on the logistics of keeping the customer safe. Like I said if I can make few bucks my wife will let me keep on "playing around" with this but if I can't show her its worth my time and effort she is likely to give me the boot from the garage.

I'll likely be working with a friend in NoCal soon too. So who knows.

I honestly had no idea(and still don't have much of an idea) where to go with this. I would like to make few extra bucks and like I said I would like to help other people in their growing efforts. Please please send me any suggestions to try and get this off the ground. I have never done...

I just thought I could make a few extra bucks and I like doing and I have all the stuff to do this out of my garage. As I said I'm a cancer research scientist, not ready to quit my day job just yet. Guess at this point the hydrostores are still the best place to go. My wife thinks I nuts and...

Like I said I was pretty excited that I could do this and really thought alot of people would get use out of this. It works beautifully every time.

Hmmm guess I didn't think people would think I was a cop but I guess that makes sense that people would be weary. I assure you I am simply a fellow grower that happens to be a molecular geneticist as well. As I said I developed this because I could and was really sick and tired of investing...

I also have card as does my wife. Got the idea to offer the service to others from my local hydostore owner. He was very excited about it and I went out and made up business cards. I guess its best to go to hydrostores at this point. My thoughts on dispensaries is the same as yours. As far...

No not the average grower can do it. I have the equipment to do it here at my house. I do other genetic analysis as well. I would have to have people send me tiny pieces of young leaf and I can do the analysis for around $10/plant. Price could go down if the volume request was significant...

method called SCAR (sequence-characterized amplified region). But now that I have the marker I use a simple method of PCR amplification to see if the plant contains the male marker or not. I use a small piece of the cotyledon or first leaf to extract the DNA then run a PCR reaction using small...

Hi all, this is my first post. I'm actually a scientist. I currently do cancer research but I had been a plant molecular geneticist at one point. I started growing a couple years back and wondered if it would be possible to determine the sex of a plant simply by looking at the genes. In this...
