The good news is everything in the system has grown like crazy this past week, with most plants at least doubling in size from last week. Here is how they looked at 7:30am this morning - about an hour after sunrise:
The bad news this is how they looked three hours later in the full FL morning sun, even with the feed/water interval backed down to a flood every 10 minutes:
As I mentioned in the first post, the lettuce, spinach and chard are fall crops here so I wasn't expecting much - but damn - they were sure looking pretty. The misses has ordered me some 40% shade cloth so I.m going to give that a try just for the heck of it. Even if I have to wait until fall for the greens, I've learned the concept will work anyway.
Bumped the feed to 1.4ec and still keeping the ph around 5.8.
Next update in a week. Should be interesting to see what survives.
