Soil 6.2–6.8 (aim 6.5). Coco\u002Fhydro 5.7–6.1 (aim 5.8–6.0).\u003C\u002Fli>\n\u003Cli>EC is nutrient strength. Start low, increase as plants ask. Burnt tips = too hot: pale and hungry = increase slightly.\u003C\u002Fli>\n\u003C\u002Ful>\n\u003Cp>Always calibrate your pH pen monthly.

Most printed charts are aggressive.\u003C\u002Fli>\n\u003Cli>Additives that actually move yield: silica in veg for stronger branches, beneficial microbes for root health, PK booster in mid-flower, but only if the base feed is stable.\u003C\u002Fli>\n\u003Cli>Back off when runoff EC rises week over week or leaf tips burn.

Sterilize scissors. After 3–5 days, start LST: gently bend main branches outward and tie to the pot rim.\u003C\u002Fp>\n\u003Cp>ScrOG steps: set net 8–12 inches above pots, veg until 70–80% filled, flip to 12\u002F12, then tuck shoots under the net daily for 10–14 days as they stretch. Stop tucking when the stretch ends and let buds rise.\u003C\u002Fp>\n\u003Cp>Autos: usually skip topping. Use LST only, bend the main stem gently after the 4th node and spread side branches.\u003C\u002Fp>\n\u003Ch3>Defoliation Do's And Don'ts (Autos vs. Photos)\u003C\u002Fh3>\n\u003Cul>\n\u003Cli>\u003Cstrong>Do:\u003C\u002Fstrong> Remove large fans blocking multiple bud sites, thin dense interior leaves creating moisture pockets, and clean up larfy lower growth that'll never see strong light.\u003C\u002Fli>\n\u003Cli>\u003Cstrong>Don't:\u003C\u002Fstrong> Strip plants bare. In photos, do a light defol before flip and again at day 14 of flower. In autos, take a leaf or two at a time, spaced out, never heavy sessions.\u003C\u002Fli>\n\u003C\u002Ful>\n\u003Cp>If you're unsure, take less.

Aim 24 °C-27 °C days, stage-appropriate RH\u002FVPD, and PPFD\u002FDLI targets.\u003C\u002Fp>\n\u003Cp>Build big roots in fabric pots, keep pH\u002FEC in range, train a flat canopy (LST\u002FScrOG), and finish with a slow dry ([15.5:celsius]\u002F60% RH) and 3–6 week cure.\u003C\u002Fp>\n\u003Ch3>Photoperiod vs. autoflower: which produces higher yield and why?\u003C\u002Fh3>\n\u003Cp>Photoperiods usually yield more because you control veg length and training (topping, ScrOG) before flipping to 12\u002F12. Autoflowers finish faster but have limited recovery time, so heavy training can reduce output.\u003C\u002Fp>\n\u003Cp>New growers seeking maximum yield often choose feminised photoperiods for flexibility and canopy management.\u003C\u002Fp>\n\u003Ch3>What PPFD, DLI, and VPD targets should I use to maximize cannabis yield?\u003C\u002Fh3>\n\u003Cp>Seedlings: 200–300 PPFD, DLI 12–15. Veg: 400–600 PPFD, DLI 25–35, VPD ~1.0–1.3 kPa. Early flower: 600–800 PPFD, DLI 35–45. Mid\u002Flate flower: 800–1,000 PPFD, DLI 40–55, VPD ~1.2–1.5 kPa.\u003C\u002Fp>\n\u003Cp>Use full-spectrum LEDs, raise intensity gradually, and watch for light stress.\u003C\u002Fp>\n\u003Ch3>How should I feed and water to prevent lockout and boost yield?\u003C\u002Fh3>\n\u003Cp>Match pH to medium: soil 6.2–6.8 (aim 6.5), coco\u002Fhydro 5.7–6.1 (aim 5.8–6.0). Track EC: seedlings 0.4–0.8, veg 1.0–1.6, early flower 1.6–2.0, late 1.4–1.8 mS\u002Fcm. In soil, water to 10–20% runoff then dry back; in coco, feed to runoff daily. Adjust if tips burn or leaves claw.\u003C\u002Fp>\n\u003Ch3>How much yield can I expect in a 2x4 tent with a quality LED?\u003C\u002Fh3>\n\u003Cp>Results vary by genetics, training, and environment, but a common indoor benchmark is roughly 0.5–1.5 grams per watt with dialed conditions. With a true 300–480W LED over a 2x4, many growers see 6–16 ounces total.\u003C\u002Fp>\n\u003Cp>A flat ScrOG canopy and proper dry\u002Fcure help hit the high end.\u003C\u002Fp>\n\u003Ch3>Do organic or synthetic nutrients maximize cannabis yield better?\u003C\u002Fh3>\n\u003Cp>Both can deliver top yields if pH\u002FEC, irrigation rhythm, and environment are dialed.
