Can anyone please advise of a good Calcified Seaweed Supplier I can use. Thanku

 Good evening to all out there, I have just joined this site & I do have a question about a good Calcified seaweed Supplier if anyone knows of one, please advise.

Now a little about me. I have a 10 rod Allotment which I acquired from my Father some 4 years ago, Good fertile land on a Private Allotment Association site. This site allows Chickens & Beehives to be kept only. We do not have a stores hut so we buy all from outside.
 Some use a local Farmer for Manure, but there have been problems with the farmer using some insecticides that find their way back into the manure which cause loss of Vegetables if used. So not as  many use the farmer anymore, myself also.
I try to look after my plot & grow my produce & learn to live with the animals & insects (within reason) that try to stop my produce reaching its end result. I use such treatments as rags soaked in Jeys fluid pinned to a stick around the plot or urine collected & squirted around the plot. This I find tends to work too.
I keep the Stinging nettle growing till after the Red Admiral & Peacock Butterflies have pupated then its hacked down & put in a bath of water till well rotted. The sludge is added to the compost heap & the water used on the plants. I use { 6X  100% Natural manure fertiliser 15kg bags} which is a Rich Manure Fertiliser better than the raw material & get superb results on produce.
Well I best finish now, I getting a bit long winded. So now you got an Idea what I am about. I look forward to your advice and comments with regards to the Calcified Seaweed & wish you all a good weeks growing .

Hello . Thanks for your info. Calcified Seaweed is better to use on brassica beds as it does not burn the stems or roots where Lime does. The CS also is an excellent soil conditioner and adds trace elements too. I used it a while ago and forgot how good it was. I am suprised its not used more as its benefits over the use of Lime is so more useful. 
Still I do need to find a recommend supplier that sells the stuff . I do not just want to get any old Calcified Seaweed of the internet, as you don't really know if it is Legit.
Thanks
