Silicon, recirculating pump, heatpad/waterproofed electric blanket, and more volume or larger rez to keep pH & E. C. MORE Stable after adding all other things like nutes apart from that, yeah
The silicon for the plants strength and also pH up I use it for but the recirculating pump larger rez & electric blanket with temp control.
I truly believe a large rez is key for keeping everything stable longer.
Meaning less checks if doing it manually.
Sometimes the heat from the recirculating pump is enough heat for the rez in summer and the electric blanket with heat control pad.
Also use electric blankets on pots/under pots if not growing hydro also.
