Features to consider when choosing lettuce varieties for greenhouse growth
Before we dive into the specific lettuce varieties, let’s talk about the features you should consider when choosing the right ones for your greenhouse. These features will greatly impact the taste, texture, color, and overall success of your lettuce crops.
First and foremost, consider the flavor of the lettuce varieties. Lettuce can vary in taste from mild and sweet to slightly bitter. Determine what flavor profile you prefer and choose varieties accordingly.

Lastly, ease of cultivation is an important factor to consider, especially for those new to greenhouse gardening. Some lettuce varieties are more forgiving and easier to grow, making them ideal for beginners who want to enjoy successful harvests without too much hassle.
