I posted my growing cupboard a couple of months ago, and have since then completed a number of changes to the setup.
1. I've added ventilation. The humidity got to high and was causing mould problems. I've taken a bit of a hit to the internal temperature, but I don't want mould and also 90%+ humidity around mains electricity is kinda scary.
2. I've added two more lights in tge form of DIY grow lights. I designed these lights to have a low profile and fit on the side shelves of the cupboard. They use high power LED tape, mounted to aluminium strip. They operate of 12V which I'm a lot more comfortable having in this space.
I've only added the new lights last night, but I'm hoping I can get a bit more heat even with the ventilation from the LEDs and their power supply.
