4 Rules Every Grower Should Know
Match Light to Space
Rule of thumb: 30–50W true power per sq ft for LED. A 2×2 needs ~120W, a 4×4 needs ~480W.
Start Low on Nutes
Begin at 50% of recommended dose. Plants show deficiency before toxicity — easier to add than fix burn.
pH is Everything
Soil: 6.2–6.8. Coco/Hydro: 5.5–6.2. Wrong pH locks out nutrients no matter how much you feed.
Air Exchange Every 3 Min
Size your inline fan to exchange tent volume every 1–3 minutes. Oversize slightly for carbon filter resistance.
