Some say seedlings shouldn't be put into a hydroponic system until a few weeks into the Vegetation stage. Liquid Jade disagrees. He puts his seedlings directly into a hydroponic system.
He also uses moisture-barrier plastic which allows water to splash oxidized water onto the plastic and end up in the middle by the seedling's roots. This techniques also prevents algae from forming on hydrogen pellets.
So why does Liquid Jade put seedlings into a hydroponic system?
He wants them in natural environment as soon as possible. He talks about this plus a lot more in his video.
