Activities October 26, 2011

The rate of growth of the Balcony Hybrid tomato plant growing under the 6 band flower series light by Pro LED System is hard to believe. There are several trusses with flowers forming and some of the flowers are opening already. It is at the point that I must give some serious consideration to placing a support system around the perimeter of the plant.

On the other hand, the plant under the 90 watt red/blue/white LED is not doing well at all. The problem is not so much the light, as my home built AutoPot system. The plant has been severely overwatered to the point that it may not survive.

The problem, as I see it, is that the tray I am using is too large for one plant. The tray works alright in the greenhouse, as the plant is using a lot of nutrients through transpiration. In the tent, the humidity is high and the plant, being small, does not use the nutrients as fast; as a result it sits in about an inch of liquid for several days. My solution is to use a smaller tray, or add some ballast in the tray to displace some of the liquid. Also, I am thinking that it would be best to control the nutrient flow manually until the plant is more mature. In my view, problems are part of the learning process and that is what this is all about.

Another batch of lettuce, Dutch Winter Brown, has been planted in one of the ebb and flow systems to replace the batch of Grand Rapids lettuce I harvested yesterday.

As the rhubarb chard is nearing harvest, I have started a replacement planting of Early Wonder beets for greens to replace the chard.
