There are both subsidies and loan programs. As far as I know (I am not a farmer, nor do I know any greenhouse farmers very well), lots of it is private capital though. One of the biggest banks in the Netherlands (Rabobank) has a (positive) reputation for financing farmers and other agricultural firms. (also a negative one due to the LIBOR scandal, incidentally)
