hey there tiki! good job getting this far and i know you’re doing your best to help your plant.
what is the soil that you’re using right now? also, can you get access to or buy any sort of drainage material… perlite, pumice, vermiculite, rice hulls, small rocks? i think the sand could possibly help, but if there’s too much of it your mixture may get more compacted or almost like mud i imagine, depending on the sand (is it fine or coarse?).
are there grow stores, nurseries or home improvement stores nearby where you live? is it easy for you to order items online?
can we get a picture of your new soil/sand mixture?
