Hey, I’m Manolo from MJF – your go-to grow buddy 🌿. I blog about everything cannabis cultivation: from sprouting your first seed to harvesting top-shelf buds. Whether you're growing in a closet or a custom-built growroom, I’m here to share tips, tricks, and tried-and-true methods to keep your plants (and you) thriving. Light it up with knowledge and let’s grow together! 💡🌱 #GrowWithManolo
How to read cannabis leaves in coco, DWC/RDWC, aeroponics, rockwool and other media. pH/EC ranges, the most common symptoms (Ca/Mg, K, Fe…), quick fixes and “false alarms” (root oxygen, solution temperature, spray nozzles). Tables + downloadable charts.
A complete guide to leaf symptoms in cannabis: nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, manganese, zinc, copper, boron, molybdenum, chlorine, sodium, and toxicities. Nutrient availability vs pH table, diagnostic checklist, quick fixes, and “false alarms” (overwatering, wind, light, pests).
How to feed cannabis in soil: when plain water, when half-strength, when full; pH 6.3–6.8, a simple water–water–feed rhythm, how much water per pot and how not to overdo it.
A practical comparison of watering marijuana in coco and in soil: rhythm (daily vs. every 2–3 days), pH, the “pot weight” method, how much water to actually pour, and how not to overwater.
How to water marijuana in soil: a 2–3 day rhythm, recognizing signals (thirst vs. overwatering), the “pot weight method,” pH 6.3–6.8, how much water for 5/10/20 L, and a day-by-day plan for seedlings.
Simple coco grow guide: what pH to set, why calcium and magnesium matter, how often to water, solution “strength” (EC), ready-to-use recipes and costs (EUR).
Head-to-head Sea of Green vs. Screen of Green for 60×60 and 120×120 cm tents. Veg time, plant counts, PPFD, cycle plans, costs (EUR) and ready-to-run layouts
How to do supercropping (pinch-and-roll) indoors, when to use it, how to limit stretch and manage risks. LST, SCROG, LED distance, aftercare and costs — a practical guide.
Main-lining (manifold) step by step: when to use it, classic cut scheme 2→4→8, week plan, gear under €40, common mistakes, autos, and PPFD/VPD tips for even colas.
Foxtailing in cannabis: when it’s a light/heat problem vs. just the cultivar. How to stop it in 24–48 h and protect density, flavor, and resin.
Set the ideal LED-to-canopy distance: starter tables, light burn vs deficiencies, when to raise or dim, plus PPFD/DLI tips for an even, stress-free canopy.
Set grow light without pro gear: measure PPFD & DLI with a phone, quick DLI math, correct LED distance, targets for veg/flower — no light burn.
We regularly drop posts here about growing marijuana. Swing by often if you're as into it as we are.
