AeroGarden (Modified) To Grow Broccoli
Whilst I await some parts for my hydroponic grow room, I wondered about how to grow some broccoli in the AeroGarden. As it stands the basic AG cannot grow broccoli due to it's small grow holes, so, why not rip it all apart and convert it to something that can...
Briefly, here's how it's all done - although it's an involved process which requires some hydroponic parts (hydroton, air pump + airline, airstone, net pots and rockwool - or some other grow medium).
1. Remove the complete central column and pump from inside, plus also the front hinged flap.
2. Using the AG as a template, cut out a new top grow base - I used plywood.
3. Cut out a hole for a 2" net pot which will take the hydroton and grow our broccoli.
4. Wrap everything in black plastic bags to keep the water away from the wood. I also used heat reflective tape to cover the top.
5. Put your airstone inside and connect it all up to your air pump, cover the electrical contacts at the back with plastic to stop them getting wet. We'll leave everything turned all off at the moment while the seeds germinate.
6. Germinate your seeds first in rockwool in a warm dark place. I planted two in case one did not sprout.
7. Once they have sprouted give them light from the AeroGarden lights, grow them a little while longer before transferring them to your net pot and hydroton.
8. Add your hydroponic nutrients (or spare AG tablets) and grow your broccoli...
I'll expand on some more of this as I go through the process of getting this grown. I know it's a little involved but what the heck, something different.

Aha. So you're growing something else in your new LED light cabinet. 
They could go in there but I'm keeping this grow in the kitchen, much cooler in there.
T&M doesn't say, but Park Seed says Belstar broccoli grows 16-20" tall. I thought that was more the size problem with broccoli in a classic-sized AG?
That's why I only put one hole in the new base, the Classic will only just support that.
Hi Peat,
Looking forward to this grow! I wonder how cabbage would grow? I've got seeds for mini head cabbage. Hmm... I've had it with the mega cherries. I might give it a shot. Good luck!

I wish I could say that they'll definitely work, it's something I've never tried.
I'd hazard a good guess that you will be OK, some websites list the EC for cabbage and I've not seen anything that says you can't.
Give it a shot, I'd like to know how they get on also. 
Hi Peat,
Cool! Glad to see the sprouts. I'm curious how Broc roots grow hydroponically.

Messed this one up...
I neglected to check on the rockwool, it dried out under the lights and all the sprouts died - doh!
Planted some more which will be better looked after.





















To be continued once the broccoli I planted today (Belstar F1 Hybrid) sprouts...
Of course, you don't have to limit yourself to broccoli - cauliflower, cabbage, butter head lettuce for example. Plants you were unable to grow before due to the constriction by the original holes.
