Both my greenhouses are lean-to and partly shaded by trees so don't get as much light as I would like, but they are also both quite small so keep the heat well.I was wondering whether light and heat are equally important. I'm growing toms, peppers and aubergines. Was thinking of covering the non-glazed walls with silver foil to reflect light. Do you think this would be worth it,or would it reflect heat too and lead to too much heat?
Just realised this should be in "under glass" but can't move it.
