Here's the news from the growing room this week...

The pH is quite stable.  I've gotten it down to "business as usual".  Here's my current thinking on the pH control for the aeroponic TurboGarden:

• Ideally, the plants would like a pH of about 6.5
  
• The plants continually lower the pH in their normal life cycle (tomato, strawberry, eggplant).
  
• My water at the house is approximately pH 6.8-6.9.
• I no longer adjust the wate's pH down when making a water change; the plants will take care of it themselves.  The pH isn't far outside the ideal range, so I can get away with it.
• Every day, I check the pH.  I'll usually add about 20ml of pH increaser at a time, as necessary.  Since the main reservoir is approximately 25 gallons, this is a reasonable amount to add.

The tomato plants are honking huge.  As you may remember, I expanded the lighting support frame a few weeks ago.  I added almost two extra feet to accommodate the rapid growth of the tomato plants.  Here's a photo from this morning:

The tomato plants are huge (approaching 5' tall).  We've actually been pruning them back to keep them from getting in the lights "burn range".  Oddly enough, they have not flowered yet.  I'm expecting that when they finally do flower, we'll be looking at a huge crop of tomatoes.

The strawberries are fruiting frequently.  We're probably getting about three berries per week from each plant.  That may not sound like much, but they are still immature.  My older strawberry plants (in the back yard) produce a far greater quantity.  However, they do have a two year advantage over the aeroponic youngsters.

The eggplants are growing.  No eggplants yet.  The herbs are looking herb-like.

Our lettuce is still doing well, but is not long for this world.  The time of the great cutting is approaching quickly.  It's just as well, aphids have been a continual problem in the MegaGarden (they originally arrived on the backs of the strawberry plants that we transplanted).  Although the Organocide has helped, the aphids are tenacious.  Not for much longer though, as we're about to cut down their whole habitat.
