What affects do the high temperatures have on your Tower Garden?

Here in the Pacific Northwest we are having a real heat wave. Temperatures have been in the 80’s and 90’s for the past two weeks.
During periods of extreme heat, plants are being stressed when temperatures are above 85 degrees. The plants will literally begin to cook! They need more water as they deal with the loss of water by evaporation through their leaves.
It is important to check the water level daily. Keep the Tower Garden reservoir full at all times.
If you can, have buckets of water sitting out a day in advance to let the chlorine evaporate. During times when the plants are using a lot of water, only add Tower Tonic about every third addition. Too high concentration of minerals is not good for the plants.
You may need to protect your plants from too much hot sun. Just like people, your plants can be “sunburned” during times of high temperature. Use a plant cover cloth such as the Tower Blanket to cover your Tower Garden. This could be especially important in the hot afternoon.
I run the pump continuous and sometimes hand spray the Tower Garden plants.

See how long the stems are on the chard and kale plants of this Tower Garden.
This is a Tower Garden that I planted last November before Thanksgiving. It spent the coldest part of the winter in my greenhouse with grow lights. There just isn’t enough daylight this far north to grow in the winter without grow lights. I took it outside in March, and put an aquarium heater in the water reservoir to keep the water at 65 degrees which is important. That is the perfect soil and water temperature for maximum growth.
It’s now the last week of June 2015. We’ve been eating Chard greens from this Tower Garden since Christmas. Notice how long the steams on the Chard plant have grown because we pick the older leaves and leave the tip to continue growing. The stem climbed higher searching for ever more sunlight. It is amazing how these plants have been in this Tower Garden for 7 months now and just keep on growing and producing leaves for us to eat. The weather has been very hot here the past week which has caused the Chard plants to begin to bolt and get too tough. I am now going to harvest the leaves. I’m going to plant new starts in this Tower Garden for a second crop. Since plants grow 30% faster in a Tower Garden expect to get a third crop before we get a hard frost.
