The proof's in the pudding.... as they say. Your main concern is providing plants with the properly balanced nutrient solution.
Your main choice is how you get there. You can pay through the nose and use watered down bottles with cute pictures or
buy bags of agricultural fertilizers that make...
You can run many different light setups on a certain driver. A driver's specs will tell you what type of parallel/series circuit you will need to build to use the driver optimally.
Had the first range day with my new 1862 36 Cal. Colt Pocket replica....not exactly what I would call enjoyable. The caps just constantly shredded and jammed the hell out of the revolver. I used 777 charges from 12 grains up to 20 and they all shredded the caps. I'll have to find some real black...
Canoed leaves are usually a condition of high wind, high heat, low moisture and/or high EC.
Also stressed plants do better in a milder climate.
Things you can do to alleviate issues....
Raise light and/or add a diffuser, HPS puts out lots of IR that will heat leaves over tent temps.
Lower...
My guess to what is happening is all the moisture from the combustion and the slightly damp warm air around the burner are getting sucked up by the damper and exhausted out of the basement. The only thing left is the cold dry air in the rest of the basement.
My main battle during winter basement grows is humidity. The furnace sucks all the humidity out of the area. Not uncommon for the area right around the furnace to be 12-15%RH
I have been able to smell my grow coming into the neighborhood, probably 500 ft away. This was in a fairly open area though.
I would think the large number of trees would help some....but to what do degree is only a guess.
I was in peat mix, either Sunshine #4 or Berger BM6...I can't remember now. I usually watered once a day at around 1.4EC, during heatwaves I would water twice a day at 0.8 EC. Final pot size was 7 gallons.
Just run the main 3 part and use the rest to fertilize the lawn. I just harvested using Jacks and rainwater and the plant had green leaves right to the end.
Ballpark use for Calmag is 0.3-0.4 EC.
If you start with RO, find the dose that brings water to 0.3 EC, then add your required nutes.
Different brands will have different concentrations, so going by EC is your best bet.
