January 7, 2012 journal






Ava is picking our flowers, and presenting them to her mom and grandmother, just as quickly as they open. And, that is fine with me, as there is no sense in keeping them in the grow chamber where they can't be seen and enjoyed.

At this time I am growing several varieties of lettuce to evaluate how they grow, hydroponically, under my specific conditions. I have found that, in addition to being difficult to start, Australian yellow leaf lettuce has a wicked tendency toward tip burn. On the other hand, I have found a variety called Two Star, that is really doing quite well without a sign of tip burn.

The Fordhook giant chard, show in the lower photo, appears that it may turn out to be the very best batch of chard I have every grown, and, I have grown some great chard in the past. These plants are only four weeks from the date that I started the seeds, and they are the most compact chard seedlings I have ever grown, including in the greenhouse.

The Little Leaf cucumbers growning under the red/blue/white LEDs are finally producing female flowers. The EC has been adjusted to 2.4 with a pH of 5.8.

Hi! I just want to thank you for all the awesome information you provide in your blog (I have learned so much).

I have a question though. How have you built your ebb and flow system for the lettuce (the stores charge so much and it looks like you are using rubber maid bins). I currently have lettuce growing in a drip system using rubber maid bins, but your ebb and flow looks like a better use of space. I tried searching your blog but perhaps I am just not looking in the right spot.

Thanks so much!!

It is nice to know that someone is getting useful information from the blog.

To answer your question regarding the ebb and flow systems; I use restaurant bus boxes. One with the cover forms the reservoir and one on top for the growing tub. In other words, two boxes and a cover make a system. They are inexpensive and durable and large enough to hold about fifteen four inch net pots each.

Look online for them. I have used this company many times.
