General Hydroponics Rapid Rooter Grow Plugs – Item of the Day — 9 Comments

  1. What brand net cups/pots did you prefer.  Also do you use Texas Tomato food or the trio you highlighted from amazon as your fluid?  Thanks


    • I use CZ net cups as they are the best I have found

      On fertilizer I use both Master Blend and Texas Tomato Food

      Neither has worked really better but the Texas Tomato Food may be better for long term use (tomatoes, peppers, etc) especially in large kratky containes, but that is just a guess. The Texas Tomato Food is easier to mix, the good news is I am going to cover it all in depth on todays show.

  2. I might have missed it, but are the Rapid Rooter Grow Plugs reusable, or are they a “one and done” item?

    • Officially one and done but I reuse them and discussed it on Friday’s show.

      I use plain old drugstore hydrogen peroxide at about 30% with water to soak and reuse.

      I reuse some with smaller root systems and I always reuse the ones that fail to germinate. Some I have used a third time they get weak by then. If they have big roots in them I use them once and compost.

  3. I’m about 3 weeks into my first try at hydroponics using Jack’s method of Rapid Rooter plugs, net pots,  aster blend mix, aluminum chaffing trays and the little indoor green house and I really love it. I’ve started a bunch of seed and am transplanting out into pots since I don’t have a way to do grow lights (no electricity yet). The only problem I’m having is that I can’t get amazon to ship the Rapid Rooter plugs to me anymore. Last month I got two packages but this month it won’t ship to my residence address anymore. Do you have a second best type of starting medium you could recommend? Thanks!

    • Finally able to order more Rapid Rooter plugs. Yeah!

      In case it ever happens again though or I want to shift to something less expensive or more reusable. Do you have a second best recommendation?

      Thanks again.

  4. Did you decide on a better pan and a better board?  You mentioned that you would talk about that later but I have watched all the videos in the Kratky series and nothing else was recommended.  You mentioned both an 18 hour light cycle and a 14 hour cycle.  Have you noticed any difference?  Jack, thank you so much for recommending this setup.  I have grown tomatos, various herbs, beans, corn, sunflowers and zucchini and transplanted into the garden with wonderful results.  I do not even plant the lettuces and other greens in the garden but harvest from this system as they grow so fast.  I use the fertilizer you recommend – Urban Farms Texas Tomato Food and Vegetable Fertilizer.

  5. I am looking to buy a couple of these for seed starting early next year. Since they are moist should I freeze them or dry them out until I am ready to use? Just looking to prevent mold.

    • No need to do all that and if they dry you just wet them again so no worries on that. Unopened they seem unlikely to mold, I mean may be keep them in the dark. I have them sit around for months though and never had an issue.
