Day 31-33: Finishing channels

10 days ago, most all the seedlings in rockwool went into the two nursery channels.  Early last week, I found some of them had grown roots 2-3″ in a single day and were ready for planting into the finishing channels. I didn’t know exactly what to look for, so I moved over a few to the finishing channels that looked promising.

Then I went out of town for 5 days. Oops.

The system ran fine. I had a friend come check on it, as well as monitored it with a IP-camera that can pan around the room to see any water leaks, plant height, or people breaking in thinking I’m really not growing basil.

The growth over 5 days was huge.  Here is a basil plant that had 3-4 leaves and 5-10 small roots (less than an inch) when I left.  And 5 days later its, well, a root ball thingy.

The PH and EC in the reservoir didn’t move too much – so we’re still within a good healthy range.

Current Scoreboard

So after moving everything from the first planting from the nursery channels to the finishing channels, the score is:
Sweet basil: 37
Bibb lettuce: 7

Day 32: finishing channels mostly filled and lit


This is from nearly 50 seeds of each plant type.  The lettuce I killed off early due to a lighting issue. What happened to the rest?


There were 2-3 basil plants that I moved a bit too early.  Their roots were not long enough to touch the bottom of the channel to get their nutrient film; so they died.

2 basil plants just didn’t root well.  Instead of many small roots with root-hair, they tried making one large root down to the bottom.  This left them wilted. I went ahead and removed them, as plants at this stage don’t seem so keen on quick recovery.

There are a few basil plants still in the nursery channels.  Some just didn’t grow quick, some had multiple seeds sprout within the same rockwool and I clipped the larger sprout (so that some are smaller and a bit behind the main cycle, in an effort to have a continuous supply of this stuff).



Day 33 lettuce woes

Day 33 lettuce woes

The lettuce plants are growing pretty good.  A few have an issue with some browning on their interior leaves.  Initial research says lack of iron, which the basil might be taking most of.  A few adjustments and few days should tell.
