Now they look good. Very different physiology as you can see. I apploed the 3rd product of Mycoterra: Quimera, a trichoderma harzianum based protection against pathogens.
I have changed my old hps lamp to a new CMH: Lumatek electronic ballast + Lumatek 315w 3100K bulb + Lumatek Tekken Pro MIRO reflector.
I decided to use CMH for different reasons :
1. As the growroom is in a cold room I need some extra heat.
2. Even though i didn’t find scientific research in this topic but plants grown under a CMH are said to produce the highest amount of terpenes, and I am more concerned about the quality of the weed I harvest then about the quantity.
3. CMH has a spectrum that only very expensive LEDs can compete with.
4. I don’t grow so much indoor so difference in efficiency (PAR/ watts) did not convince me to buy a LED fixture.
