Check out this 20 plant grow under a single LED grow light.

Who am I looking for?

Looks like Darryl has done some solid work once again with testing a lot of different led spectrums / configurations...
Would be interested to hear his thoughts on a strictly vegetative led for produce such as lettuce. Maybe @chazbolin can chime in?

This shit is like rocket science to me... I'm thinking that I want to know more... Feed me because I'm hungry!!!

Yes, please check in with Darryl. He knows how to get Growpito. You can also just Google our name to come to our little place on the web. Hope to hear from you soon.

Why not make your own?
You can also use activated carbon foam mats as they are offered in aquaristic trade, and then cut them into cubes. Mix these cubes with rock wool flakes, and your selfmade gpito is done. (5$/m² e3ay, take this with big pores, in 1" thick and cut about 1" big dices)

On the activated carbon surface, beneficial bacteria and fungi can settle, same principle with bio-carbon in your compost. In the aquarium the bacteria settle on the carbon surface and decompose nitrates (fish shit) and as a substrate they give room to trichoderma, mycos and useful bacteria to colonize.

That's not rocket science, they were just the first to come up with the idea of mixing both.

Part of the issue with the current rockwool flakes or cubes on the market are the binders and surfactants that reduce the capillary action and ability to hold water again and again. That's why we have used virgin rockwool in our product that has not been sprayed with any chemicals.

In how far the gpito flakes were treated with wetting agent or something similar I can not say. I don`t use any. I'm a confident soil user but will do a coco DTW run next time.
