I hope it grows for you, I'll be watching :)

My biggest concern is going to be taste. Without that cold environment I have a feeling the sprouts may end up a little bland or maybe even more bitter. Not sure. Sauté them with bacon and that takes care of that problem ; )

Bacon makes everything better ;)

That's a good idea. I may do a test and put some in the freezer and keep some out and see if I can distinguish any difference in taste. That's months away though. They grow so slow. Thanks.

Timely...I just got my Brussels sprout seeds today.

I like to roast them until they caramelize. The sprouts, not the seeds. :)

are the roots a tad brown?

Yes. And so is my water. I use Floralicious Plus, sea kelp and humics, and it gives the roots a brown tinge.

As long as you don't have a moldy, rotten, putrid wooden bench next to your plants...

ok hvg, just wondered.

mitchnc it wasn't next to plants, even worse - I had the air pumps sitting directly on it. I put a picture of it on my idea book just in case somebody wants to see how not to do hydro.

Here's my brussel sprout plant about 10 days later from the previous images. Growing like crazy.

Wow!

I watched some videos on Brussel sprouts and the stalk gets huge.
Can a 3" net pot contain it?

I have no idea. I have seen some plants get huge while others stay on the smaller side. I used the same plants I put out in the garden which were "generic" brussel sprouts seeds, not any specific variety that stays small or gets big, I don't know. That's why this is an experiment. If I can get them producing well and tasting good and this plant gets too big I'll hunt down a smaller variety to do on a regular basis.

A 3-inch would probably be fine for the stalk size but it may not provide the support needed. I am using a 6-inch net pot lid that is much deeper so more support.
