Comparing Lettuce Growth from a Hydroponics System vs in Soil | Seedling Experiment
Hydroponics or soil-what’s the best way to grow lettuce? In this video, I’ll be conducting an experiment trying to answer just that! There will be three groups: a group that will grow in my hydroponics system, a group that will grow in my soil garden, and a final group that will grow in both soil and hydroponics. After showing progress time-lapses over multiple weeks, I’ll share the results I arrived to.

    Great video Jessica. One comment from me to help others. When first trying the sensor, put it in PH 4 solution. If you tried before calibrating with tap water you will get PH error. Use right fromm the beginning Solution 4, calibrate, use solution 7, calibrate and done!

  • @cronx1337
    @cronx1337 ปีที่แล้ว

    Fixed systems should not be 'flat', they are at 45 degrees facing south for optimal sun exposure. You should be tracking energy spent on servo vs overall power efficiency of stationary vs tracking system. Results may surprise you.

  • @FREDNAJAH

    great experiment and data collection. did you account for the power used by the motors to move the panel and how did that effect the benefits of tracking? can it scale up to a 200w panel.

  • @thekinarbo
    @thekinarbo ปีที่แล้ว

    My understanding is that a tracking system is not necessary or cost effective in every application. For ground mounted solar arrays it's cheaper to just add additional fixed panels to make up for the lost watts. With fixed panels there are no moving parts to maintain, repair or replace and the system as a whole is gobs cheaper, even with additional panels. For backyards with limited space and only a few large panels/arrays on poles a dual axis system makes sense. If you look at most big solar farms they are fixed arrays/no tracking.

    Hi Jessica. I have the Eco Worthy dual axis tracker. I have 2 arrays. All panels are identical; Trina 400w. 1st: 2 panels laying on the ground, tilted about 12" and facing West. 2nd: 1 400w panel on the tracker. It has been averaging just over 1 KWh a day.. 1.8KWh\312w, 1.16\320w, 1.12\317 for the past 3 days. Late yesterday after the sunset, I added a 2nd 400w panel to the tracker. It's now getting 1.24KWh. The 1st array is getting 890Wh and just 417w. So YES.. trackers work.. I have 6 new bi-facial 200w panels arriving on Friday (1200w) which I will mount on the tracker. Overall these 2 arrays make about 2KWh a day.. but that will go up drastically soon. I have a Victron 150\100 for the 2-400s and a Victron 150-45 for the 2nd one. I have a video on my channel of it. You should do this same test with a dual axis tracker. I'm certain the numbers would be more..

  • @paulnese1090
    @paulnese1090 ปีที่แล้ว

    Again as others have said, excellent work and excellent documented results. I have a several of comments: 1) You should view another TH-cam experimenter who demonstrated a "genius setup" tractor of two large solar panels balanced via a hinge on a see-saw horse whose panel tracking is automatically done ONLY by an additional small pair of steering solar panels powering a $20 motorized actuator arm. No sophisticated computer serup! It's an extremely simple setup. The key is to reverse the power leads from the small steering panels so to supply voltage in an additive/subtractive method to the actuator arm's stepper motor, by changing voltage director to the DC motor, as the Sun moves across the sky. Thus advancing or reversing the tractor's DC motor direction and the large solar panels position. 2) In your "fixed solar panel" experiment test you placed it totally horizontal, flat eg 0° degrees. Whereas, in actual fixed solar installations installers set the fixed panel say at 32° deg angle to face the region of the sky where the maximum Sun tracks across the sky at higher intensity say 10 AM to 3 PM. Perhaps if you had placed your fixed panel in a similar angle Sun facing way, it seems to me you would capture more solar power for the day. Perhaps enough, where the power differences between fixed vs tracking would be smaller. (Maybe next time.) 3) My thought considering how complex and expensive Sun tracker systems can be to gain a 25% to 30% improvement, wouldn't it be simpler and more cost & power effective for home setups just to add an additional fixed non-tracking solar panel. 4) Again, you produced EXCELLENT data comparison results of a single tracker vs a fixed horizontal panel.
