Logan was curious about luffa growing methods and previously heard that trellising should yield straighter, more marketable sponges from luffa plants. He tested this in Ontario at Trent Farm Research Centre and his results showed:

• Untrellised luffas that received 3.0 kg of chicken manure yielded the highest among six combinations of trellising and fertilizer
• Trellised and untrellised luffas that received 1.5 kg of chicken manure performed similarly
• Trellising had an effect on luffa growth when no fertilizer was added, but both trellised and untrellised yields were lowest overall
