After many weeks since the initial germination and growing stage. I hereby pronounce that my first hydroponic butterhead a resounding failure. Well, maybe not resounding but indeed the result was not as expected. Here’s how my growbox looks like now.

Does it look like butterheads to you? Guess not. Looks like a bunch of weeds. Here’s a close up.

The leaves are definitely growing. But it just doesn’t seem like it’ll morph into a butterhead anytime soon.
Initial research on this matter does point to the lack of light, causing the ‘trunk’ to not strengthen and support plant. My plant is now kinda leggy and can’t support itself.
It’s back to the drawing board for me. I’m not giving up. I’m now thinking of designing some better lighting for the growbox and will attempt the butterhead again. Will post up my 2nd attempt when I start it!
