Default life of lettuce in dwc question

Been picking outer leaves of my buttercrunch in DWC, for a while now.
I'm wondering, will my plants last indefinetly as long as I keep changing water+nutes, or will they eventually go to seed?
I have another batch almost ready to transplant into the DWC but hate to tear the exsisting ones out as long as they are still producing.

Hello newhydro16,
Eventually they will begin to seed as they get older, but you can pluck off the leaves until they do. However the younger leaves/plants are usually more tender and tasty, so you may want to harvest/rotate the whole plant anyway. That way your harvesting younger leaves/plants to eat, as well as have a continuous supply.

Hello newhydro16,
As long as it tastes fine to you. Once the lettuce plants become mature, and/or start to elongate and begin to seed they tend to become bitter. But I have soaked the cut leaves in cold water for a while and that get's rid of a lot of the bitterness.

Thanks again.
The leaves are getting longer, seem to taste ok, wife really seems to enjoy them. I guess when my new ones are ready, Ill yank /eat the current ones. Id start another dwc tote, but Ive got quite a bit invested in this already, and room is an issue.

They do look kind of long and sparse, but I'm very new to this and still learning. I'm sure you will get some answers here from GPS frontier or someone more knowledgeable then myself.

Hello Mervin,
I don't know anything about your system and growing conditions but Mmy first thoughts are your plants may have stem rot. From the pictures the rockwool cubes look quite wet. My second thought is you may have inadequate lighting.

Thanks for your response gps. I think you have suspexted right. Now i can see some root rot on my romaine. Any suggestions on how to decrease the chances next time I plant? Are these romaine good as nothing already? Im using kratky method btw. The system is placed on our terrace but i think it has bad air circulation.
