I have two 130 watt CFL lamp 6400K in a
Small grow box. Length 1170mm, Depth 520mm and height 790mm. Having problems with heat…
have a couple of fans working inside the box but not sure if the lights are over kill.
Thank you for all the advice. Those plants went from outside to inside and i’ll be honest, I rushed the grow space. So everything was reactionary. I have started again, and have everything I require. My grow is space is still only slightly too hot. Averaging 30 degrees and 60% humidity. These are just over a week old and are on 18/6 cycle grown in Coco feeding Canna A&B and Rhizo. Getting some leaf curl is this due to heat stress?
It could be a number of things. Overwatering, too much nutrients or the space is still too hot. Hopefully you’re not feeding them full strenght at this point. They’re too young. Use half the amount of reccomended nutrients or less. Temps should not be higher than 77 Degrees. The light should be at least 25in away from the plant.
Hi J, cool air pools low and hot air rises, having your “in” vent at the bottom and your “out” vent at the top will utilize natural convection increasing overall air exchange. In a tight space like that you may want to consider investing in LED, more bang for the buck as more electrons are transformed into protons thereby less electrons are transformed into thermal units (heat).
Another no no is bringing outdoor plants inside, there’s pests outside that will thrive indoors that otherwise have predators outside (aphids mites and others) challenging you to eradicate them by whatever means possible.
