  • Im interested in buying 5 of these Pargro 4 Rockwook Blocks. I am growing Swiss Chard that I currently have in 1.5 Grodan starter cubes and they need to be transplanted somewhere ASAP. I have around 28 seedlings. Can green leafy vegetables grow well in Rockwool Blocks like these Im looking for the cheapest way to get this grow going. Thanks!
    Yes your Swiss Chard will perform great in 4 Rockwool. The one thing to remember when using Rockwool is that it holds a lot of water so dont over water the plants. One time a day with a good soaking will be sufficient. If the plants seem to be growing slowly you may need to take the watering back to once every other day. Good luck and thanks for your interest in Atlantis Hydroponics!
