Ron it really is not practical for you to make some contraption to give your plants the cold treatment this late in your growing season. If it is that cold there today it would be far easier just to place it outdoors in a protected spot. Since it is so late there, I would just pass on the cold treatment. The plant will still grow and produce for you. Yes, the plants still need light to photosynthesize. If you are hardening them off during the process then keep them out of direct sunshine.
The mycos will help your plants with the uptake of nutrients and allow for a healthier root system. Healthy roots mean healthy plants, provided that you keep the diseases at bay.
We have had strange weather here as well this winter. Time will tell what summer brings.
