小黃瓜為現今常見的生食蔬菜之一，目前的小黃瓜都是以溫室栽培為主，然而小黃瓜植株的病蟲害相當多，在植株生長時需要噴灑大量的農藥，這原因使得這些小黃瓜並不適合生吃，因此本次實驗希望能夠藉由植物工廠來產出無毒無農藥且品質又高的小黃瓜。實驗的結果顯示了，小黃瓜植株在植株工廠中的生長狀況良好。藉由測量酸鹼值(The power of Hydrogen、簡稱pH)與導電率(Electrical resistivity and conductivity、簡稱EC)來得知植株在生長1個半月後會需要大量的養分與水分的供給。小黃瓜的果實在上架後的第30天即可採收到第一根。關於產量：(1)未修剪的部分為219根，共28.2公斤，可採收3個月。(2)有修剪的部分為529根，共63公斤，可採收4個月。(3)特殊條件為143根，共8.6公斤，可採收1個月。進行果實品質的比較，以筆直果數量與彎曲果數量的比值作為果實品質的量化，結果顯示，在植株有做修剪的情況下，果實品質從9 (第一個月) 下降到2.3 (第4個月)，而未修剪的則從2.3 (第一個月) 下降到1 (第3個月)。最後觀察枝條數對於產量的影響，結果也顯示留3條枝條的產量最高。

Cucumber is one of the most economic vegetable worldwide. It also is one of the highest pesticide residues crops. For maintaining cucumber quality, high frequencies of pesticide spray were applied for cucumber cultivation. This study's aim was to produce the high quality cucumber with pesticide-free. Plant factory is a better approach to produce crops under correctly controlling plant growth conditions. The results showed that cucumber plants grew vigor under plant factory. By measuring and correcting pH and EC values, the hydroponic solutions was maintained optimal conditions for plant growing. The first fruit was harvested the thirty days after planting. We compared different thinning treatments on fruit quantity and quality. (1) 219 numbers of fruit and 28.2 Kg of total fresh weight were harvested three months after planting under control (non-thinning) treatment. (2) 529 numbers of fruit and 63 Kg of total fresh weight were harvested four months after planting under thinning treatment. (3) 143 numbers of fruit and 8.6 Kg of total fresh weight were harvested one month after planting under the special treatment. The radios of straight and curved fruit were 9:1 in special treatment, 7:3 in thinning treatment and 6:4 in control treatment, respectively. Finally, we alsocompared varied numbers of main shoot on yield. The results showed that tree numbers of main shoot was the best yield.
