Are there good source of aqueous smoke water for seed germination in the US? There are some products in South Africa, and Australia.
There are pretty good evidences that aqueous smoke water can break seed dormancy, and Karrikinolide (KAR1) is likely to be the active component. I know some people use fire for germination, but it would be nice that if I can do better control. According to data, if you give too much, it reduces the germination. With the smoke water, we can easily control the dosage. Most of the time, they bubble the smoke into water, and saturate it with KAR1. The saturation occurs fairly quickly (about 10-20 min of bubbling). And 1/10 dilution of the saturated smoke water is a good starting point. So I'm wondering if it is available in the US.
I probably have to make a DIY smoke water rig. Has anyone made something similar (with cheap and commonly available components)?
Here is a related topic, and the last post contains the rig, but it uses bee smoker and aspirator.
Can anyone tell me how to produce smoke water which is used to promote seed germination? - ResearchGate
Here is a more full scale tech. pub.
I'm trying tuberous Drosera seeds from Australia.
