That was a really cool video! There is a cloning nursery around my parts that also messes around with plant tissue culture. I believe he said the jelly like substance is called agar. I think plant tissue culture is so cool!
I wonder if it's the same stuff that gel2root uses

@rmoltis my 4ft t5 set up is only 4 bulbs:cry: but it fits my nursery section perfectly. I run a mixed spectrum.
@incogneato the power of your t5 set up is truly impressive. I bet rmoltis would love to grow a beast under it! That fixture is so cool.
Ya I feel like it's not the best method for smaller growers like us, but for a huge facility I'd bet it saves them some money in some form or fashion.
