Growing Red Leaf Lettuce Hydroponically

Share This Post

IMG_3144Red Leaf is here.

Since our very first produce bounty in mid May, we’ve been harvesting lettuce every week.  It has been very exciting and gratifying to see the crops grow so well in the Gen. II CGS. While we’ve been mostly growing Butter Lettuce (bib lettuce), a few weeks back we planted a Red Leaf variety and were rewarded with an awesome harvest last week. Red leaf is a type of loose-leaf lettuce, with delicate leaves, despite its crunchy stem in the middle. Similar to Green Leaf, but with
maroon pigment deposited on the edges and the leaves themselves, this loose leaf variety likes to sprawl a bit while it’s growing and thus requires some “dressing up” before it can hit the shelves. To help with that, we’ve created a new branding look for this lettuce – an Alaska grown twist tie with a custom flag that shows variety, growing methods and its origin. Think of it as nifty outfit for its debut at the stores that also helps collect all the leaves in one awesome bunch. As always, you can find this beautiful variety at Bell’s Nursery and select Carrs/Safeway stores in Anchorage, Alaska.


What’s the difficulty level growing produce hydroponically?

Our goal is to demonstrate to our future clients the simplicity behind growing fresh and nutritious produce hydroponically, here in Alaska and around the world. We’ve already researched the type and quantity of nutrients and water you will need, the seed varieties, the proper growing medium, the time from seeding to harvesting, the best LED lights, the right temperature and airflow, all to optimize the growing environment and to take the guess work out of hydroponic farming. The key thing is consistency. Consistency is the secret behind being able to harvest mouthwatering greens week in and out, which is the principle behind growing produce in the CGS.

So what are the steps to perfectly grown produce, each and every time?


Step 1. Take seedlings from the starting area and transfer to finishing trays. Each seedling comes in a Rockwool cube – not dirt, no mess and easy to handle.

Step 2. Put trays with new seeds in the starting racks, where sprouting begins

Step 3. Harvest in due time. We can customize a schedule that fits your needs. We harvest every week.

Step 4. Top off nutrients, pH buffer and water

Step 5. (OPTIONAL) Depending on your “personality”, you can talk to your plants or perhaps play some music. What kind of music? Play something you enjoy, which will make your harvesting time that much more exciting.

So how difficult was it to grow this Red Leaf? As “difficult” as it was growing Butterhead, which just loves being in the water!

Red Leaf Nutrition.

per 100 grams:

Over 100% of your DV of Vitamin A ( 7493 IU, 150%) and Vitamin K (140 mcg, 175%) ! As it turns out, red leaf is also a good source of iron (1.2mg, 7%), folate (36 mcg, 9%), manganese (o.2 mg, 10%) and not to mention a concentrated source of phytonutrients. This is a very low calorie food with a low glycemic load and high fullness factor.

If you pair this lettuce with another food that’s complementary to red leaf’s nutritional profile, you will reap great benefits from your meal.  For example, to round out another fat soluble vitamin and add a great protein source, pair Red Leaf with wild caught Sockeye Alaskan salmon, which has good levels of vitamin D (not to mention a host of other benefits). Need more iron? Try a Red Leaf and spinach salad with some chickpeas or beans. (loads of iron there). For heme iron, go with high quality beef liver. For vitamin C, you can’t go wrong with Kiwis or Kale. Just one cup gives you 164 mg or 273% DV and 80.4 mg or 134% respectively. 

So there we have it. Grow Red Leaf, eat Red Leaf, pair appropriately and be happy!

As always, to your health!
