What you're describing has been solved by the indoor hydroponics growers - they use grow tents which reflect light and manage ventilation/ humidity, etc. Is there a reason you want to use a refrigerator, other than it being free?
Most indoor growers don't bother with cucumbers unless they're growing at greenhouse scale. A single plant makes a TON of vines and foliage before it puts out any fruit.
A CFL bulb is unlikely to produce enough lumens for any flowering and fruiting plants. It's probably enough for leafy greens (I grow indoors all winter using 4x T5 compact fluorsecents)
Most people use HID or High Pressure Sodium lights in their grow tents
My advice is to look for a used grow tent on Craigslist or Facebook marketplace if you want to try peppers, tomatoes, etc.
Or setup a simple leafy greens setup under CFLs to try out the concept

Led lighting is getting fairly reasonable.
