Speedy Boom Auto

I started an experiment, I managed to get from the shelf that I have near my grow box, a small space measuring 90x35x70, I coated it with some insulating materials and diamond mylar, I put the cob led I bought last year, a pc fan, a usb humidifier, a small stove that heats the room and an airontek hygrometer, I bought 2 3.6lt pots and I cut them in half making them 1.7lt, I want to try to make small plants but with many full buds, I still don't know whether to use the topping technique on all the apicals, placing an LST side by side so I can keep the plant low, we will see later what to do.
