Most clear plastic is considered direct sunlight - unless there are special filters in the plastic. That is to say, if the only thing between your lettuce and the sun is regular clear plastic, you should be fine. As and FYI there are multiple categories: 1. Direct sunlight - some plants require direct sunlight on their leaves 2. BRIGHT shade; for example when I lived in a Condo, my balcony had no direct sunlight, but because the buildings beside my building had huge glass windows I had VERY bright shade and could grow most full sun potted plants. This also applies to living near the water, where the sun gets reflected-- MOST full sun plants are fine with REFLECTED light but not all. This could also be a a very sunny field, with shade cast from one building, chances are good that would be very bright shade 3. Sun/Shade with all its variations 4. Light shade and 5. Deep shade like the middle of a dense forest. I see no reason why you could not grow SOME of your veggies in the bright shade. I find that many plants labelled full sun, are not. For example: strawberries are generally labelled full sun. However, strawberries TEND to grow naturally in the shade of other plants: woodland or forest floor, in meadows shaded by other plants. I've noticed that any of my strawberries that get full sun tend to have burnt leaves, and the best yielding strawberry plants are in a cool predominately shady areas. I suspect that planting your plants that tend to bolt in a cooler shadier area would be very helpful. I've even grown cherry tomatoes in very bright shade with great success.

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

To increase the levels of Molybdenum (Mo, also called Molly) in your soils -- wood ash (from a fireplace, firepit, or barbeque) can be incorporated into the soil. Alternatively, Banana peels are an excellent source of Moly. Animal manure tends to (grass/grain/vegetable feeders) tend to have a decent amount of Moly in their manure. If all of these are out of reach, perhaps try incorporating wood chips/bark mulch in your garden. You can make bark chip paths, use the paths, then the following year when the chips are broken down mix them into the soil. OR -- just mix the wood chips (bark, mulch, whatever) directly into the soil. As the wood is breaking down it takes a lot of nitrogen. I would expect to find Moly in leaf mulch - but have not found any reliable sources that have stated this as a fact. If you choose to use chemical forms of Moly remember that this is a TRACE element - VERY little is needed and over application can result in a OTHER problems. Staying organic almost guarantees you will not over apply. If you live in an area where wood burning stoves and fireplaces where common for heating (pre- electric fireplaces and stoves) - and you know people old enough to have been around when wood ash was common in the garden (there was no place else to put it) - they can tell you how amazing the gardens where back then.
