Without sunlight plants become thin weak and spindly. There are varieties to grow in summer and others to grow in Autumn Winter. I generally don't grow things from end of Nov to end of Feb because of the heat and summer conditions - heavy rain and wind.

Lettuce struggles in heat. Finding the balance is not easy but all plants need sun

Lettuce grows best in cooler conditions. Varieties of lettuce that are grown in the summer (Great Lakes, etc) tend to be coarser textured and not quite as sweet as varieties grown in cooler weather. Because they are a leaf vegetable and not a 'fruit' vegetable they will tolerate less light. Morning sun up until late morning would be fine. Too much shade will make them weak and spindly. Trust this helps.

Shadecloth covers assist in growing. Keep up the water.

Planning on planting tomato & lettuce together. Is this a good idea? Any advice would be appreciated.

Plant the lettuce on the northern side of the tomatoes or plant far enough away so that the tall tomatoes plants don't shade the lettuce. Lettuce need sunlight to fully grow.

I live on east coast and wondered whether it is a good idea to plant lettuce seeds and what type for summer 2020/2021?

The open leaf varieties. Cos, butter crunch, oak leaf etc. Lettuce seedlings take a lot of care to grow. Seeds need to to be very close to the surface to germinate, only a couple of mm of fine potting mix or seed raising mixture to cover them. Water with a sprayer or mister not with a hose. Water 2-3 times a day, keep the soil moist. Will need to grow them for 3-4 weeks before transplanting them.

I am trying to grow lettuce in soil I have added my home compost to. All seedlings get nibbled down to nothing at night and I can't identify what is going it. I live in Perth and very keen to know what is doing it and how I can control them

Go out at night and see what is eating the seedlings. Sparrows eat my lettuce the first couple of months of the year. I have a bird trap now. They also eat the heart out of my snow peas certain times of the year. Work out how to put a border around each plant or the whole block of lettuce. Like a 90mm pipe 100mm long and put oil or grease or Vaseline on the outside. Or look up similar things on the internet for slugs, snails etc. Or build a frame and cover with shade cloth.

Bill: Lettuce going straight to seed usually happens when it's too hot or dry (cabbage & silver beet tend too as well). As you water daily I am guessing that the lettuce are getting too much sun, have you tried shading them from afternoon sun? I have some lettuce growing in the shade of my tomato forest (planted a little close together this year). The lettuce get maybe 2 hours direct sun first thing, then shaded for the rest of the day, and they are doing really well.
