Hi Derek....It protects seedlings from the dreaded damping off problem..nothing worse than having a whole tray of precious seedlings flop over and die .I mix some up in hand sprayer and spray the surface of the compost prior to sowing,hope this helps....Alan

p.s most decent g/centers sell it

Another question on the seeds front.
I have grown various things (mainly flowers) from seed over the years, but do tend to have the problem that they're always a bit leggy. 
Why is this?  Is it due to not pricking out thoroughly?

Thanks

PS Started digging the lottie this week - it's enormous! (Only really noticed once we started digging).  fells good to get going though.

It is a combination of too much heat and/or too little light. If you cannot move the seedlings to a lighter situation turning down the heat slightly will make them stockier.
There are some cultural practices that will reduce damping off so that Cheshunt compound is unnecessary. Ensure good ventilation (or air flow at night from a heater), water only when necessary and early in the day so that the soil surface dries out by nightfall (covering seeds with fine grade vermiculite rather than soil is a great help with that) and making sure that seeds are sown thinly to begin with. With reference to the latter the use of modules/cells (as opposed to old fashioned seed trays) will also contribute to avoiding seedlings loss. As Cheshunt compound is unobtainable over here these practices have had to work for me as I don't use even harsher products.

Hay Big Al! Is that you?  ::)

Hi John...whilst I fully agree with and support good plantsmanship rather than using chemical control, I feel that for beginners just starting out on the steep learning slope of greenhouse gardening need someone to point them in the direction of these remedies as all too often it is reported on these boards of disasters with beginners' newly emerged seedlings falling over and they not having a clue what caused it!.
I must admit although having had many years of greenhouse gardening I still use Cheshunt compound,mainly because I am severely disabled and am unable to monitor my greenhouse to fine degrees,I have found it to be an inexpensive and successful remedy to "damping off" problems.best wishes....Alan

Hiya Bun.....yes it is me...Big-Al ;D

Cheshunt works for me , as will bordeaux mixture for larger plants (I have to admit that much as I would love to garden organically there is no chance owing to the proximity of local farmland, which is sprayed to within an inch of it's life). I find dithane good for other fungal infections.

Basically they contain a chemical which kills the fungus responsible for damping off.

Alan, I completely agree and I wasn't attempting to usurp your post but just provide more information for the large number of beginners who are appearing here. The point you make about constant surveillance is  important and one I should have included too.
