[TRNSYS-users] Plant model

[Marie-Hélène]

Hi Jean-Pierre,

I have created a TRNSYS component based on a crops model developed by
Graamans et al. (2017). The model has been validated for hydroponic
lettuces growing in steady-state conditions under electrical lighting (no
natural light). If you are interested, I would be happy to share the model.
Please feel free to contact me at my email address.

Graamans, L., van den Dobbelsteen, A., Meinen, E., & Stanghellini, C.
(2017). Plant factories; crop transpiration and energy balance.
Agricultural Systems, 153(Supplement C), 138-147.

Kind regards,
