Disclosed are methods and kits applicable to sequencing methods, such as Sanger dideoxy sequencing methods. The light-emitting device comprises semiconductor layers of p-type and n-type nitride semiconductor, semiconductor-surface-electrodes to apply currents into each of the semiconductor layers, an insulating layer which holds the semiconductor layers, and mount-surface-electrodes. The geo-textile material is configurable to various container designs that permit the non-conventional plant placement including the mounting of the plant containers on vertical surfaces, flat surfaces, and by suspension from ceilings and walls. The signal outputs of the mixer circuits are supplied to respective LPFs to produce demodulated signal outputs. The vendor-neutral agent also includes the capabilities of the general-purpose agent and manages other setup needs, such as configurations, best practices, and license management.
