Electric propergator question
My propergators are the kind that have no regulator on them so I can't change the temperature setting. Having sown some seeds and placed the trays in the propergators I am wondering if I should lift/remove the lids during the day as it's quite hot in the greenhouse, currently 34. I do have foam type shading so the trays are not in direct sunlight and there is plenty of light getting in. Im just concerned that they will be far to hot and not germinate. Many thanks.
