Transcript of Hydroponics VS. Traditional Soil Growth

1
20
2 liters
2 small bags Background Information The primary macronutrients for growing plants are phosphorus, potassium, and nitrogen
The secondary macronutrients for growing plants are sulphur, magnesium, silicon and calcium
Hydroponics differ from soil growing because they absorb nutrients directly from the base; water infused with the proper amounts of the macro nutrients Problem/Question Which system, hydroponic system or regular soil growth, would work best to grow cherry tomatoes? Hypothesis If cherry tomatoes are grown in both hydroponic and soil grown systems, then hydroponically grown cherry tomatoes will have a higher fruit yield and faster growing rate because hydroponically grown plants absorb nutrients directly from the base in more precise amounts than soil growth. Material List Materials Quantity Bucket
Large Pots
Nutrient Solution
Cherry Tomato Seeds
Small Pots
Enriched Soil Procedures 1) Make four rows with 5 pots in each row, leave a one foot space in the middle of the four rows, then name one of the sides "Hydroponic" and the other "Soil Grown". 10 2) Cut a piece of Styrofoam sheet to match the dimensions of one side of the pots 3) Cut hole's in the Styrofoam perpendicular to the center of each large pot, as wide as the upper body of the small pot right underneath the rim of the pot so that the pot would hang from its rim and dip its lower sections into the top of the large pot. 4) In the 2 rows of pots labeled "Soil Grown" get enhanced soil with the same nutrients as our hydroponic formula and fill each pot 1cm from the top. 5) Fill the small pots up with gravel three-fourths to the top for each pot. Gravel 1 bag 6) Mix the nutrient solution with the appropriate amount of water then fill each each of the large pots labeled "Hydroponic". 7) Once you get one pack of cherry tomato seeds grab 3 to 4 and separate them when you put it in the pot. 8) Continually water the pots labeled "Soil Grown" while adding the nutrient solution daily to the pots labeled "Hydroponic".

Core: 4 ;c Data Analysis A lot has happened during the project. The average height of the potted plants on pot 1 was 6.72 cm, pot 2 was 7.61, pot 3 was 6.50, pot 4 was 7.22, and pot 5 was 7.67. Now the average height on the first hydroponics plant was 5.36 cm, the second hydroponics plant was 3.69, the third hydroponics plant was 3.88, the fourth hydroponics plant was 5.27, and lastly the fifth hydroponics plant was 5.21. Conclusion The problem was trying to solve which plant growth method, hydroponics and regular potted soil growth, would help grow the plants much better. The hypothesis stated that between the hydroponics and the potted soil the cherry tomatoes would grow best hydroponically because the plant can absorb water directly from the base easier. Unfortunately the hypothesis was wrong. You could tell that within one week the potted plants were surpassing by 2.4 cm. Some errors though could have happened like measuring inaccurately. Plus the plants may not have received enough nutrients for the plants to feed off of. If this did happen then improvements that could have been done was to put more water and nutrients in the hydroponics as well as measure each plants directly from the base with accuracy. But even knowing that with the control of how much nutrients we want to put (hydroponics), it was good to know that doing something practical or traditional into growing plants would create a healthier plant. This was a good problem for us to solve of finding out which type of growing method is better for cherry tomatoes.
