Hydroponic culture

I am building a small indoor garden  on a bay window in my house. I have tried to cultivate some harbs and baby lettuces with hydroponic culture.The hydroponic culture pots were handmaid using the pet bottles or the plastic plates and  alminium buckets. The baby lettuces easily produced buds and are growing step by step. I have to thin out these soon.

 

However, the harbs haven't grown so well. Only a few chervils are slowly developing buds. And recently, I  found some leaves with characteristic of chaevils!

I am looking forward to the plants growing!!
