How to Grow Red Lettuces Yourself?
Generally, lettuces grow best when exposed in broad daylight. But it is also important to remember that you have to plant them in places away from extreme heat so they won’t bolt—which makes the leaves taste bitter, break and wilt easily.
For starters, lettuce seeds can be grown in small pots 4 weeks before the last cold season, then you can transplant them outside in mid to late spring. But if you’ve decided to plant your lettuce in the summer, try to look for an area with a lot of shade since the summer heat can potentially damage your crops.
Lettuce grows in various soil types, but they mostly favor growing on soil that is well-drained, cold, and coarse with plenty of moisture. Therefore, before you plant your lettuce on the ground, you must ensure that the soil contains high levels of organic compost materials—this is to encourage the lettuce to grow well. 
Reminder: Lettuce grows best in soils with pH levels between 6.2 to 6.8. So, if necessary, make the proper soil adjustments before you start planting.
Red Lettuce vs. Green Lettuce
Did the thought of the difference between Red leaf lettuce and green leaf lettuce ever occur to you? Although closely related, the red and green leaf lettuce has more distinct differences than might you have imagined. In this portion, we shall compare and contrast green leaf lettuce with its red leaf counterpart.
We will talk about how different they taste from each other, their nutritional differences, and which one is better overall.
The Red and green leaf lettuce have quite identical qualities flavor-wise. However, if you closely examine them, you can notice some differences between the two. Both are delicious vegetables with a slight sweet profile and a subtle nutty taste. The red lettuce gains this bitter edge to it the more it matures.
And this bitterness in Red leaf lettuces is known to be quite overpowering when mixed in salads and vegetable wraps. While this can also happen with some varieties of green leaf lettuces, the probability is not as high compared to Red leaf. 
Although all members of the lettuce family are nutritious, this does not imply that they are all nutritionally equivalent. In case you don’t know, there’s a rule that applies to the various members of the lettuce family. And it’s that the deeper the shade of green the lettuce leaf has, the better it is for you in terms of nutrition value.
And while Red lettuce is visibly the much darker one between the two, remember that we are talking about the shade of ‘green’ here. So obviously, green leaf lettuce is a much healthier option. Also, if we’re not counting the fatty acids Omega 3 and Omega 6, the amino acid Tryptophan, and the anthocyanins, Red lettuce loses to green lettuce in every given nutritional category. 
Red Lettuce vs. Green Lettuce: Final Verdict
Evidently, green leaf lettuce is the clear winner here. It contains more important vitamins and minerals like vitamin A and K, which helps fight cancer. And it even has more levels of vitamin C, which helps boost immunity. Lastly, green leaf lettuce also has more micronutrients and fiber than Red leaf lettuce overall.
