Rockwool Hydroponics Propagation and Transplanting Complete Guide

Seven minutes—packed with info! We take a look at Grodan A-OK starter plugs (stonewool cubes), Grodan Delta 3-inch and 4-inch rockwool blocks, Hugo 6-inch blocks, Big Mamma 8-inch blocks, Unislabs and loose fill rockwool growing media. We cover pre-soaking rockwool, adjusting pH, charging up with hydroponic nutrients, hardening off seedlings and cuttings, and transplanting into soil and soilless media such as coco coir.

Everest thank you for the college level tutorial, rockwool. I had no idea how extensive the rockwool uses are and  the huge variety of sizes of shapes available. I'm happy to be here, thanks again for your presentation.

[StewartLeishman]

Great video! Best I’ve seen explaining rock wool. Thanks!

[RickMarshallMaps]

Great information on starting plants in hyrdoponic systems. I appreciate the video. I am just getting started.

I was wondering if I should leave the wrapper on in the first stage, glad I watched this! I'm trying to get herb seedling like cilantro to grow in my Mr. Stacky system I have in my patio and will plant the rockwool in coconut husks afterward.

Thanks! I was wondering if I could transplant my cubes into soil and you answered my question. Good thing coz I already did. lol

[sweetlovetiger]

wow your good on making things simple ty. I'm glad you are taking the time to show people first starting with rockwool. I'm going to keep watch for more

I and an old soil grower. I tried 1 time to germinate in Rockwool lost all six plants I think there was to much water in blocks don't know but definitely made me stay away from Rockwool. If you have any suggestions I am willing to listen. And yes I followed step by step for preparing Rockwool. I am used to 90% Success and will Rockwool I had 100% failure.

[amberswartz]

This was incredibly helpful! Thanks for the tutorial!

Will rockwool work for any plants? I am training to grow perennial flowers from seed and hoping rockwool can provide a medium that will minimize seedling whilt and just be less of a mess.

[WhyNotRichie]

Yes.... Lettuce.. exactly what I was looking for.

[DeathCoreBrii]

Damn man, I learn so much from you and I'm laughing at how wrong I was doing it.

Hi reviewSearchs. Can rockwool be re-used? That's a great question! Thanks for asking. Some commercial growers enjoy many successive crops from rockwool slabs by steaming them after the plants have been removed and then replanting. Smaller growers can also do this - a few slabs can be heat treated by pouring hot water through them. Solarization is also possible, as is using chemical disinfectants, although care should be taken to rinse the rockwool well with plenty of water after using these. Commercial Grodan users have the option of the Grodan recycling service, which picks up the used slabs and recycles them into new product. However, smaller growers with just a few slabs of used rockwool can recycle the material by shredding it and reusing it as a growing media, as a component of potting mixes, or by incorporating it into outside soils and gardens.

Hey Everest! quick question, how do you feed your seedlings, do you spray? and how often do you feed?

[analyticalmastermind]

Good content and you cover it at a good pace, thanks for the upload.
