Well I did a res change today on both the bubbleponic system and the waterfarm. I went to full dose nutes and supplements on the white rhino in the waterfarm. That flourescent t-5 setup is sooo nice. I can just lift one side up and the plants on the left are still getting nice close light and I still have plenty of room to do what i need to do. The waterfarm is nice and easy to change. i just unplug the airline that runs the dripper, let it drain for a min. Then lift it right out andput it into a bucket that's pHed to 5.8 with ther recommended dose of clearex. Then I plug back in the airline and it drips the clearex through the hydroton while I'm cleaning everything out.
Then I clean out the res with soap and water, rinse it well, fill it back up, mix in the full strength soup. pH it and I'm good to go. undo the line, pull the bucket put it back in the res and Voila! easy as pie...
speaking of pie...
Anyways here some pics.
