NFT, All Plants Showing Signs of Wilting

NFT main system. The heat index is now 95, all plants are starting to show signs of wilting. Looks like if this heat wave keeps up, all the plants will die. Adjusted the pH to 6.0, Hoping this might help the plants accept more water.

Plants Under Stress In NFT Tubes

NFT Tubes main system. Four plants have started to wilt. The heat index is currently at 108. I believe the plants are unable to to take in enough water due to their small root system. The same plants in the the Hydro Buckets are doing just fine in this heat. Not sure if the problem just due to lack of water or if the plants can't get air either. In any case, I added a air pump and air stone to the nutrient tank. Also increase the slope of the tubes to get more fresh water pass the roots. Checks the plants again that night and notice some were recovering from the heat.

Support Structures On Hydro Buckets

Here's a current photo showing some of the the various support structures in place to date.

There is a 3' by 7 ' grid with 2" squares over

the zuccihini and rhubarb, which is in front of me in the photo. Behind me is a a grid of poles making a 2.5' deep by 12' long structure for the tomatoes and cucumber plants.

Latest Photo Of NFT Tubes

Latest photo of the NFT tubes. The plants here are about 3 feet tall. The the hot weather finally here, plants consumed about 8 gallons of nutrient Saturday.

Vertical NFT Moved

Vertical NFT tubes were moved from the side of garage to the sunny side of the house this morning. Hopefully with more sun light, the strawberries plants will start to grow more. Only three plants show any sign of growth so far.

Top Heavy

Upon checking the NFT tubes after work today. I found that one large tomatoe branch had collapse from weight of the rain on its leaves. Good news is the branch didn't break, it just buckle. A couple of tomatoe clips and the branch was back good as new. Also all the tomatoes plants in the Hydro buckets are getting top heavy and leaning to one side. Time to put the support structure up. This will be done this week, weather permitting. Still need to move the vertical NFT tubes to the sunny side of the house.

New Grow On Strawberry Crown

Spotted some new grow on one of strawberry crowns today. Good sign that they all will all grow this season. With all the over cast and rain the past 2 weeks, I was afraid they might rot. Also based on garage roof over hang above the vertical NFT tubes, there will be be very little sun light reaching it. There fore it's time moved it to the sunny side of house next week .

New Ph Meter

Purchase my first pH meter today. With all rain the past several weeks, I was sure that the pH level would be running high in nutrient tanks. Normally I don't bother with adjusting the pH level of water. I had borrow a pH tester from a friend last year and found that my tap water ran a pH of 6.0. Good enough for me to use without making adjustments. Upon checking all my tanks, found their pH was running 8.1. Now the trick will be to keep the pH level down around 5.5. Its been raining here ever other day now for the past 2 weeks. I highly recommend that you check the pH level of your nutrient tanks after each heavy rain.

Cantaloup Added

Found a couple cantaloup plants at Jewel to today. Just for fun I added them to one of the spare buckets, on the second set t Hydro buckets.
