my grow cabinet is normally covered with lightproof foil for the night time but once I didn't notice a big hole in the foil for the whole time of grow and I know for a fact that plants were getting dim light in the night.but it didn't seem to disturb them too much if at all.I know that light penetration during the night makes plant burn their sugars that should be kept for the day but in the same time it is very rare you have the total darkness during the night outside.I don't know, maybe it results in smaller yield from outside plants? I don't have any clue. but my plants seemed to deal ok with that bit of light in cabinet.
...and the heat ... it's a nightmare...surely putting up CO2 will help but couldn't get there myself using yeasts. simply, yeasts' CO2 emission was too slow and limited in number. I think I'd need some serious hardware here to keep emission constantly on hight to reduce heat effect on plants. used to keep bucket full of ice cubes in front of the office fan.it can help but keeps you busy with ice.cheers. |
