You can probably grow most things in a pot and in a hothouse. Just grow things to their season.

New to veggie gardening. Is it too late to plant cucumber seeds? I can see from the calender this the last month. Also with a raised veggie garden will mushroom compost be the best?

This website is a guide, it is not spot on about everything. It tells you to apply local information. Gardening is a lot about trying different things but the times to plant are what they consider the best time to achieve the best results. If it says to plant Nov to Feb then you could probably plant Oct to Mar. I find mushroom compost to be very expensive for what is in it. Any kind of compost will do, manures, grass/leaf compost, seaweed, worm poo/tea, any organic matter that has broken down. An easy way is to put grass clipping/ straw etc as a mulch (only about 50mm thick) around your plants, as the plants grow the mulch will be wet and start to break down, by the time the crop is picked it is half way to compost, then dig it into the soil.

I usually grow very good cucumbers and usually Lebanese variety. This year my plant is covered in cucmbers but instead of starting off green I have an abundance of tiny yellow cucumbers on my vine. What causes this?

Phone an agricultural depart, nursery, or some agri supply company and ask if they have an agronomist. Could be some trace element deficiency.

Why do my cucumbers die and drop off when they are about 1 cm long please? They are neither under nor over watered. I dug cow manure into the bed 6 weeks before planting and have not fertilised further. The plants are very healthy and have many flowers and baby cucumbers on them.

You need bees to pollinate the female flowers, looks like you don't have any in your area. You can do it by hand, google it. Try planting some bee attracting flowers/shrubs in your yard to bring the bees to your place next time. From my experience only a small % of female flowers end up pollinated and grow into full size fruit.

Thank you. I do have plenty of bees. It is my understanding that if the cucumbers have formed then the pollination has occurred. Am I wrong? I do have plenty of 1 cm cucumbers on the bushes.
