yeah hydrogen peroxide is similar to bleach. that is what im using for seed treatment now. Could also use it for disinfecting but only comes in smallish bottles from chemist which is 10%. The GT brand i have also which is 50%. When i was a nursery hand we bleached everything in a mix of pool chlorine. might get some of that.I'm sure I posted something in the last two days but it and my memory have gone now
Hope you find a solution Candice. Bleach the #%^ out of everything and get those seeds in.
I couldn't help myself and just ordered a few more seeds that I really have no room for. They will be a late start but we have a long season so what the hell.
By any chance would Hydrogen Peroxide be any help? It solved my fungus gnat problem and they use it in hydro setups as I'm sure you know.
I went to a rural supply shop today looking for some cheap H2O2 in bulk and got blank stares, `we're all out`, `don't know when we will have more` and promises of a call back when the other guy got back which never came. Idiots. So I then stopped by a Hydro store and found that the same company that makes chilli focus sells a bottle of 50% H2O2 way cheaper than the supermarket.
edit: One variety of the seeds I ordered were Hot Cherry. I'm not giving up on this one yet.
Thanks for your kind comments.HAHA! lol thats funny! hope you feel better Nova.
Candice, I think its great that your honest! Its the only way we can solve these kinds of issues in the horticulture scene. You sound like you have a decent business growing and you have at least half a head on your shoulders when it comes to plant biology I will contribute this tidbit of info to chew on...I have NEVER had ANY plant that was 100% free of sign of disease. Whether it is early on or later down the season. Im sure you are aware of this but, I'll say it anyway..."Bacterial/fungal spores are EVERYWHERE NATURALLY". It is the conditions in which the plants are subject to, that inhibits or prohibits the colonization of those diseases. I don't believe in the "seed causing problems" theory, persay, however I DO believe that with ANY seed there are probably a MILLION spores laying dormant and waiting for the right conditions to wreak havoc on your greenhouse, germ chamber, etc etc...In my 18 years growing all types of plants, I have found that it is all dependent on conditions. If I were you, I would use a heavy sulphur based spray prob 4-6 oz of a 10% solution per gallon of fresh clean water, put it in a pump sprayer and spray EVERYTHING in your bat cave! I mean really douse it down, let it get into the soil, undersides of leaves, all branches, outside of pots, floor...everything. The great thing about sulhpur is that it is organic. It will bring the surface ph of everything to a value that will not only kill any disease currently present, but will also inhibit the future colonization of disease. It will not smell great for a day or two in there but, I PROMISE you will be disease free. Some years, I have fungal/bacterial issues that seem very stubborn. I get nearly 100% leaf drop when it hits, and it is VERY frustrating, so I feel your pain. Sulphur has never once let me down and I swear by it. You will never get your old foliage back, but after applications I always gain 100% recovery and things start branching out and going crazy again. Also, I like to add a little pyrethrins into the mix for pests. Aphids carry disease and affect plant health big time, as Im sure you are aware of, so this will help out a lot. If you don't feel like making your own spray, Bonnide makes a GREAT solution if your in a jam for time. Its called "fruit nut and orchard spray"...its about 20bucks at your home depot and will last all year at least. Humor me and try this out. Give it a week or two and let me know your results please! Good luck!
edit: while copper has been used with success, sulphur works 100% better for me. A combo would be ideal, less copper though...
I'm not sure if i agree though with the first bit about bacterial spores on all seeds or that the seed was not at fault. I still think it was seed borne as i've never experienced it before (fungal yes, but that is easy to control/cure compared to bacterial) and it was only 1 batch of seed grown in sterile, soil less conditions. Having no soil eliminates a bunch of problems already and there are absolutely no pests as they are in an enclosed environment in a shed. Bacterial leaf spot is a seed borne disease and then can be spread by splashing water, humid conditions etc.
Thank you for your input. Im interested in this sulphur spray. Will it kill seedlings though? Im not sure if they are strong enough as they only have 1-2 sets of true leaves. Would you take the hydro system apart and soak everything or would you add some to the tank to go through? I will definately look into this option, thank you so much for your reply.
