Tjena!
Jag undrar om en growbox kan få för mycket ljus... Min får ca 16 timmar indriekt ljus om dagen, iofs ganska svagt under större delen av dagen. Men ändå?
Och ja, jag såg att Xstars inlägg ovanför mitt men han gissar ju bara. Undrar om någon vet säkert hur det ligger till

Cubensis behöver inget som helst ljus, utan vill snarare ha totalt mörker, under pre-pinningfasen, alltså då myceliet koloniserar substratet.
Ljus fungerar som en ligand för cubensis i det avseendet att det triggar fruktkroppssyntes. Det är även viktigt för själva svamparna, eftersom det ger dem en riktning att växa mot. Utan ljus växer svamparna åt alla möjliga håll, ibland ner i substratet. Cubensis vill alltså ha en del ljus under fruktfasen.
För att svara på din fråga: Ja, en growbox kan definitivt få för mkt ljus. Direkt solljus är skadligt pga UV-strålningen, men även inomhusbelysning kan hämma tillväxten rejält, självklart beroende på vilken fas din grow befinner sig i. Se nedan.
Exakt hur mycket ljus som behövs under fruktfasen, det finns det många åsikter om. Här är några bra riktlinjer:
Citat:
Mycelial Types: Rhizomorphic to linear; whitish in overall color but often bruising bluish where injured.
Standard Spawn Medium: Rye grain. See Chapter III.
Fruiting Substrate: Rye grain; wheat straw; leached horse or cow manure and/or horse manure/straw compost balanced to a 71-74% moisture content.
Spawn Run:
Relative Humidity: 90%.
Substrate Temperature: 84 - 86°F / 28.8 - 30°C. Thermal death limits have been established at 106°F / 41.1°C.
Duration: 10-14 days.
CO2: 5000 - 10,000 ppm.
Fresh Air Exchanges: 0 per hour.
Type of Casing: After fully run, cover with the standard casing whose preparations described in Chapter VIII. Layer to a depth of 1-2 inches. The casing should be balanced to an initial pH of 6.8 - 7.2.
Post Casing/Prepinning:
Relative Humidity: 90 %.
Substrate Temperature: 84 - 86°F / 28.8 - 30°C.
Duration of Case Run: 5-10 days.
CO2: 5000-10,000 ppm.
Fresh Air Exchanges: 0 per hour.
Light: Incubation in total darkness.
Primordia Formation:
Relative Humidity: 95-100%.
Air Temperature: 74 - 78°F / 23.3 - 25.5°C.
Duration: 6-10 days.
CO2: less than 5000 ppm.
Fresh Air Exchanges: 1 -3 per hour. (For practical purposes, fanning a terrarium 2-3 times a day is sufficient)
Light: Diffuse natural or exposure for 12-16 hours/day of grow-lux type fluorescent light high in blue spectra at the 480 nanometer wavelength. (See Chapters IV and IX).
Cropping:
Relative Humidity: 85-92%. (For cakes: 95-100% )
Air Temperature: 74-78°F / 23.3 - 25.5°C.
CO2:less than 5000 ppm.
Fresh Air Exchanges: 1 -3 per hour. (For practical purposes, fanning a terrarium 2-3 times a day is sufficient)
Flushing Pattern: Every 5-8 days.
Harvest Stage: When the cap becomes convex and soon after the partial veil ruptures.
Light: Indirect natural or same as above.
Yield Potential: Average yields are 2-4 Ibs. /sq. ft. over a 5 week cropping period. Maximum yield potential has not been established.
Moisture Content of Mushrooms: 92% water; 8% dry matter.
Nutritional Content: Not yet established.
