I used three different methods for trying to sprout these seeds.
I put some seeds in a sealed
Zip plastic bag with a humid paper towel in an polystyrene reptiles incubator at 28ș C and connected to a timer. 12h per day
Some other were planted using the
Mrbungalow's system (What seeds have germinated for you?) with the Reptile heating mat, el. timer, and plastic boxes with lids.
12h per day at 25-30șC and the rest at room temperature (variable from 12-17șC)
And the third system I used is a plastic propagator with
turf cubes inside
and heated also with reptile heating mat in the same time and similar temperatures The two M. ingens I have, both sprouted from this last system
As subtract for the two last, I used a mixture of 1/3 perlite and 2/3

Christian from banana swap is trying to positive identify the seedlings as M. ingens, Of course there is a small possibility I mislabeled them and they are in fact the PNG Highland. I will keep you informed.
I have not had any particular problem on growing the PNG Highland but the M, ingens needed more control an treatment as they showed initially a fungus disease.
I keep M. ingens them all outside in a semi-sheltered position were they get only the early morning sun and the were the temperature range from 30șC during day to 16-17șC during night.
Humidity is the only parameter difficult to control as it change a lot depending on the winds.
Thank you Erlend for your recommendation I will check night temperature staying below 20șC
Here you have some more pictures
I will keep you informed
