Dence buds takes care, love and determination.
Lighting: Atleast 90 Wats Per Plant. 120 is better. (thats 4-5 / 400 Watt and 8-12 / 1000 Watt)
Air Flow: The plants need an air ecxhange happening around the leaves and pots at lease once every 5 mins. this restores Co2 and o2 to the plants.
Nutrients: Fixed nutrients are by far the best, this means they are readily available to the roots. there are 13 nutrients nessicary for survival, and plants can live on that. but there are over 64 different Compounds needed for a plant to survive. start researching bacteria, fungi, Plant rooting systems, and how to make nutrition compounds for the plants.
Temperature: Should be 26 C with lights on and 20 C with lights off.
