Just a few questions for thought: Is there not already spores/bacteria on the medium we sow our seeds on? It seems almost inevitable that we are going to experience quite a bit of different pathogens unless we sow them via tissue culture. Do seeds not have full/extensive protection against pathogens? Generally speaking, seeds have a seed coat which protects the embryo from the external environment and keep pathogens out. I do like your methods on seeds sowing though, and I will definitely use them since they do not seem that difficult and it seems like you have fantastic success with it. Your points are valid. However any way of decreasing fungal/bacterial contamination will help preserve viability.

However any way of decreasing fungal/bacterial contamination will help preserve viability. Before a pod is opened by you or naturally ripening , the contents are sterile , as when doing a green pod sterilization ,all that is needed is the pod to be sterilized then the contents can be placed in to a T/C jar with out further sterilization processes . ,as it is for orchids and many other similar seed pods. only when the pod has been opened to the air is the seed become contaminated, and build's more and more as time goes on, once the seed is planted ,will depend on what media you use and how you go about the germination process ,to how the seed will react ,some never get fungals other just go nuts, , but buy harvesting and storing the seed in the best practice possible its , you get less contams, I mainly doing T/c and all seed no matter how fresh that has been exposed to air is contaminated and need varied sterilization process to be able to germinate in the jars with out contamination and spoiling the seed . as far as seed being fully protected from the contamination's , well they sit and grow on the outer case or husk , and usually explode when conditions are good to make them grow, ,is a very basic explanation . if not attended to or treated will render the seed sterile or kill it if growing over the seed. and in natural germination may never show but still be there, many times seed dont germinate , can be sterile , can be wrong conditions, can be low humidity ,or contams growing inside you cant see .or the seed is just to old that you got ! my aim is , prevention is much better than trying to do a cure, as once you have contams in a T/c jar there usually is not fixing it, and the jar is spoiled ,occasionally or if your vigilant you catch the first signs of it, and can get many other seed or tissue out ,but the contaminated one is done , ,if its big enough you may be able to take it out and plant it out after some processes to fix or take the contamination off and grow into natural growth . if that all make some sense.?? will be away for a week so cant answer any more question till later next week. john .
