Just moved our blueberry girls (clones) into a more secure setup. Lined the walls with foil. Using a 90 watt LED UFO. Temperature is currently 21.5 degrees Celsius, and 31 percent humidity. Did a pH test this afternoon and consistently this week and was between 6 and 7. Had a spidermite problem initially, used natural pesticides in addition to finger smashing., taken care of for the most part, but lost some main lower leafs in the process. They also suffered a night of dehydration and heat into the 30 degree celsius area, but this is them, two days after that. There is still some browning occuring on our main lower leaves. Do they need more light? If we turn on the 40 watt CFLs (see picture) the room gets incredibly hot. We need to find a way to cool it down, but it needs to be extremely quiet. The dimensions of the space is about 2'x2'X4'. If you have any suggestions, all help would be appreciated! Thanks!
