Here are some tips from blue circle fishing club..
Good for codling at Folkestone end during calm weather in February
Best fished at low water or last two hours of flood
Open all night on Saturday
Expect flounders, Rockling, pouting, dabs and small whiting in March (but hope for codling!)
Take a trolley to lug all your gear on
This is a rock venue so be prepared to lose tackle i.e. take a load of leads, hooks and shockleader with you!
The ends are believed to be the best pegs
Folkestone end is the rockier end
The least snaggy area is the the 50 - 60 peg section
There is a steep rock edge at about 70m out which gets most tackle
The rocks have been filled with tide moved shingle to make the venue slightly less tackle hungry lately
Use heavy line (try some 50lb braid), a fast retrieve reel (fixed spools are good in that department or a Daiwa SL20SH) and a weak link system on the bottom of one hook traces if fishing on the bottom
Float fish or fish with booms down the side of the wall for wrassse, pollack, bass, mackerel, garfish, poor cod and pout when in season.
Pouting, codling and dogfish are caught when fishing out farther.
Ragworm good in summer.
Take the mackerel feathers for a high tide in summer but retrieve them quickly to prevent them sinking and catching a rock or two instead of fish.
Whole squid or live small mackerel or pout take the biggest bass in mid summer
Lug tipped with squid good in winter.
Lug tipped with fish works well.
Codling take peeler crab when they (and you) can get it!
Frozen peeler works as well .
Study of match results indicate pegs 35, 147 and 195 have been productive in the past
Be careful not to rub your line against the wall otherwise.....ping!
Take a drop net to haul up that big one 30' above the water at low tide.
The tide floods from left to right.
Trot out a float with a 6-10' drop in the tide run to cover a big fishing area.
As for Folkestone warren, no idea as I have never fished there, but you might want to have a look on here for pictures etc.

Hope this helps.

ps. we fished the hoe last year about 100 yards to the left of the path down and only lost one set of gear, and that was due to my partner cracking off..
