A. If you are indoors raise your lights up a bit higher, mist your plants with water before the lights come on and as they are going off. If you are outdoors use shade netting. Supplementing with small amounts of silica and or kelp have been known to help plants recover and adapt to heat better. Supplementing your atmosphere with CO2 helps plants adapt to hotter climates as well. The other thing you could add to the water while misting your plants is Epsom salt as it will help with any deficiencies that are usually created by hot conditions as little as 1/4 tea spoon per gallon works well some people suggest more, but if you are misting consistently then i’d go with smaller amounts, say if you are misting once a week then 1 teaspoon per gallon. Just don’t go overboard on trying to many things at once, the best thing to do is keep is simple and be patient tell the heat off the summer breaks.
