@Calzini1, it’s hard to say with your set up. I see it’s a home made enclosure. I think the cardboard is acting like an insulator and trapping heat. I’m not sure if you’re running an extractor fan to draw in fresh air from the lung room. It also depends on the ambient air temps outside of the grow box. Adding some fans may help a little bit but not going to really drop temps enough to get you from 29 down to the 20-25 range.
Maybe ditching the grow box and just keeping the plant out in the open in your house may be a better option. Do you have air conditioning in your house?
I’d have to have more information on what your plans are for growing and what your goals and budget is before being able to offer solutions. We all start somewhere and that’s alright. Growing weed is definitely not a cheap hobby to get into. I’ve spent thousands of dollars acquiring tents, lighting and equipment. But if you’re just doing this as a one off for your girlfriend to make her a bit of bud and you don’t plan on continuing to grow, then you should stick with what you’re doing now and accept the limitations of your grow. With the conditions you’re running now you still will get something out of that plant.
