Heated propagator under the bench to dark?
I've just finished making a heated propagator to go in the polytunnel for starting seeds off. It's quite large as I used a pallet for the base and I'd prefer not to put it on the staging as it takes up quite a bit of space. My question is will it be to dark under the staging for the seeds to germinate properly. Or will it be a case of them just going leggy once they do. I can hopefully get them out as soon as they germinate as I've got a heater in there for any cold nights in March/April. It will be for bedding plants like marigold lobelia, and veg like tomatoes and peppers. I can't easily move it once its set up as its going to weigh an lot with all the wet sand in as well, so i need to make a decision now.
