Thank you Gregore and Threemillswhey,
The temperature I have put it higher. It really, in Hong Kong, is simply a question of opening the door of the wine fridge. In 2 minutes, RH goes up to 100% and temp to, according to cheap hygrometers, to 15-17 ºC.
I just now finished washing the cheeses so can report:
Limburger, made 7/11, wrapped in wax paper 3 weeks later, unwrapped and put back in box in cave at high humidity, judging by condensation, 8 days ago, washed daily and left out to breath for 1-2 hours. Timid red dots, perfect surface apparently, maybe a hint of red colour.
Reblochon, made 2 weeks ago, are in cave in box ajar, hard, dry on the outside. Today a couple of blue dots dealt with a knife. Washed. A bit slushy feeling. Not a trace of b.linens, but maybe, just maybe, a hint of getting to yellowish....
Bel Paese, made two weeks ago. As per recipe ( Gavin Webber) in tight box in the normal fridge. Out to breath and wash every day. It is beginning to soften in the middle, so it must be ripening. Not a hint, nothing of b.linens. Very high RH in box. Always some liquid and condensation.
Washing is with whey brine, lightly salted, drop of white vinegar and a good pinch of the B.linens I got from Goat Supplies ion the UK.
I enclose photos of the 3 cheeses.
