Deep Water Culture Hydropincs

Today was a good day to see everything growing so well. We check out the system and everything was running great. We can not wait to try some lettuce tomorrow on harvesting day!

Today we came in over the weekend and had seen we had some good growth all over. We check the water temperature and check that pH. Everything was in specs. We than added a little more water to the system.

Today, we saw that the water level in our system has begun to get low due to evaporation.  We mixed together another gallon of nutrient mix, and poured it into the reservoir, raising the water level to a more appropriate height.

As another day passes, things begin to slow down again.  Not much has changed, we measured the pH and found that we needed to put some pH down in the water.  We were able to get the pH around 6.

After a long Memorial Day weekend, it was good to be back.  To my suprise when I went to check in on the hydroponics system, there had been a significant growth in the majority of the plants.

We have came back to see multiple sprouts, we are hoping that there will be significant growth over the weekend.  We have also checked and adjusted the pH.

We returned to class today, not much has changed since planting the mesculin, but our one sprout is still continuing to grow.  Hopefully we will see more progress tomorrow before the weekend.

After returning to class the next day, we yet again took a look at our plants.  Still there is only one little sprout that is growing, nothing else has appeared yet.  Alex and I decided after seeing this that we would plant additional seeds of Mesculin which has a faster grow rate than that of the Baby Gem.  We also added an additional and larger air stone/air pump to our system, since we have notice there has not been a lot of circulation being done with just one little air stone.

After returning to class from a three day weekend, we immediately went and checked how our deep water culture hydroponics system was doing.  Out of our twelve cups that each have two seeds planted in them, only one of them has sprouted.  At this point however, we are not concerned, due to the 10-14 day germination that the lettuce seeds have, and we may have planted the seeds deeper than we expected.  We have also checked our pH and it was still in the 5.5 – 6.5 range.

Today was a good day! Alex and I officially got our hydroponics system up and running.  Our system required us to fill it with approximately nine gallons of the nutrient solution.

Once that was finished, the germinating seeds were removed from their wet paper towel home, and two seeds were placed in each of the twelve cups, at a depth of approximately 1/4″.  Once that was completed the cups which have holes poked in the bottom to allow a flow of water to the plant, were placed in their floating holder.  An additional piece of plastic was made and cut to the size of the holes to insure that no light could penetrate through the styrofoam.  This was done to help keep the growth of allege down.  With that being accomplished we place the floater into the reservoir with an air stone.  The air stone is connected to an air pump which creates bubbles in the nutrient solution allowing it to circulate, and introduce oxygen to the plants.

Once running the pH was tested and was found to be around 7pH, which was higher than required.  In our research we found that the pH should ranged between 5.5 to 6.5 for optimal plant growth.  pH down was added to the reservoir to help lower the pH to an appropriate level. Before leaving for the day, the pH was approximately 6.5.
