Last year we moved into our new home, that had a greenhouse and a vegetable plot at the bottom of the garden. This year, I'm putting them to us. I have some herbs, flowers and vegetables (carrots, parsnips, peas & beetroot). I've always watched gardening programmes, loved my garden and read magazines, so I have so knowledge, but now I'm getting going I have a few more.
1. Whats the difference between an 8 watt propagator and an 18 watt one?
2. Whats the best to cover the greenhouse floor? At the moment, it is just on paving slabs, occaisonally I get weeds popping up inside the greenhouse and I wonder if some floor coverage would add a bit on insulation. I was thinking of laying some weed fabric, then covering with gravel or wood bark chip. Any thoughts?
3. What is best, if any, greenhouse trays filled with gravel or lined with capillary matting? I've bought some trays and filled them with gravel, but they are heavy and I'm just worried about the added weigh load on the staging. But I can see, with gravel, I have a nice moist/ humid enviroment for the seeds and plants.
Hope I haven't asked too many questions in one post, any help is much appreicated.
