A discussion of light should be accompanied by some spectrum plots, otherwise this is plastic chicken flight fight.

Thanks. Any reference please? What is the wavelength range to estimulate phytochrome red concentration?

"if that is the amount the leads to an ideal water-air ratio" There you go I think you put light over my dilemma, thanks @Sativied !! then next questions are: How do you find the ideal water-air ratio? Is it a sweet-spot? Is it a <range>? Please lets make it easier obviating for the...

What would you say is a good dif temperature (AverageTemperatureDay-AverageTemperatureNight) ? Is there any real issue with really short internodes? Shall we keep the dif temperature constant during the whole cycle or may be some benefits on playing with it? Thanks all for sharing your wisdom here

Quick answer: Of course you will got flowers! Long answer: they may stretch out, take all the energy from current leaves to create flowers and then... Nothing! Based on my understanding: If you really need to save some power: save it in veg (ensuring right plant structure) and at the...

I am doing a course on urban agriculture at Wageningen University and I am analysing about difficulties to start growing your own food: What are your biggest pains as a newbie to get started growing your own food/supply? Thanks for your responses, they will help to make our cities greener

then can you make the plant grow faster thanks to the right water schedule? can you avoid to lift the media as in some cases is not feasible (i.e: coco slabs)? finger method? what about water measure with a probe?

this is the pcb fully populated and ready to be connected and read in raspi/arduino. Im thinking about painting it with some smart polymer for water proofing
