    What I love about this channel is that, you experiment so that we don’t have to!! Thanks mate!!! 😁

  • @MattGarver says:

    Clever trick, I like the floating ice cube tray idea.

  • @Genxlettuce says:

    CZ net cups by far are my favorite of all in the industry. Personal preference , however they are built well and fit nicely into my drill holes better than the thinner options .

    I like using the neoprene discs and slicing them in half thickness. Amazing what a half thickness collar will still support.

    I went as far as just using perlite suspended in water and placed the seeds on top of the perlite. It worked well on all my lettuce germination experiments . ( about an inch floating surface worth ) it supported them too with that thickness. Like you, πŸ˜‚ always fascinated with maximizing germination – great video 🍻

    • @JimmyBHarvests says:

      Thanks AT! CZ easily the best net cups on the market imo, love that wide rim it makes them much more versatile than other net cups.

      I just started using the neoprene collars and am finding them to be very useful too!

    • @generalawareness101 says:

      CZ sucks in one respect, that kept me away from them, and that is they have CZ on the bottom where the actual root hole should be. If I am purchasing net cups I demand that hole to already be there. Luckily there are plenty of net cup makers that do it the right way.

    • @Kaalkian says:

      ​@@JimmyBHarvests with the neoprene collars and cz pots are you still using clay balls ? Cool setup

  • @megalepivolos says:

    you make everything look so easy congrats my friend excellent video

  • @harry1355 says:

    Excellent video on starting seeds. Explained very well. Thanks so much!!!

  • @AbiGJ says:

    Thanks so much for this. Very informative and complete infos. I’m really struggling with germination. Your channel helped me since it has a lot of content about it. Thank you so much.

  • @TonyVsEarth says:

    Hey man this is where my brain was going. Glad to see I’ve cube trays work. Thanks for the cutting Rockwell tip

  • @topquark35 says:

    What I find much easier is start the seeds in damp paper towels inside a container. Then you can transfer the germinated seeds to the small rockwool cubes by cutting a slit. That way you are sure all seeds placed placed in rockwoll have germinated and this will avoid more waste. I have a question though. How do you avoid algae? I find if I keep the rockwool moist constantly, algae will form on them after a couple of days.

    • @JimmyBHarvests says:

      Shouldnt be much/any algae showing up unless youve got nutrients in your water? Maybe filter your water or use distilled?

    • @patambre902 says:

      Try keeping them in the dark. Algae need light for food.

    • @Breakcaft says:

      if your water is exposed to light alge will grow inside yoir container and deplet the oxygen for your plant. try to prevent light from getting to the water. Most commonly it is because your net cup isnt sealed off from light getting into the container (a cut up pool noodle could help for example you can).
      Try preventing transparent containers, since they promote alge groth.

    • @user-nu9ry4rs2i says:

      Not rockwool but foam is what people use nowadays

  • @beautifulabstractions755 says:

    One of the best videos I’ve seen on starting seeds. Thank you.

  • @RF0rty says:

    You just gave me all the information i needed to my issues. Im ready to try again πŸ˜€ Thanks!

  • @Engineering_Science says:

    That ice cube tray with holes with rock wool on top of a container is a smart implementation, never seen anything like it.

  • @ewaserpas6697 says:

    Thank you for this video. This was very helpful. I’ve been failing at this part. Hopefully this will help me out.

  • @klearz914 says:

    ive been doing kratky for about 6 months. i learned alot here. i was putting full nutrients from the start. had no issues with lettuce and peppers but did have a cilantro die. so when i start new things i’ll start in water! and then diluted nutrients. thanks!

    • @JimmyBHarvests says:

      Lettuce and peppers dont seem to mind early feeding, ive seen that as well. But the fee plants dont outgrow the unfed plants in those early weeks. Might as well save the food.

  • @loganlentz says:

    Such a great video. Thank you!!

  • @i-a-g-r-e-e-----f-----jo--b says:

    I put my seeds in the sun on day one, lol. Glad I watched your video after that didn’t work. Thanks for the info, I’ll be subscribing!

  • @Worldwidegiantgrowers says:

    Thank you for the basic info. Looking forward to growing some veggies in the basement this winter I appreciate you.

  • @jd83241 says:

    i used to do a small one gallon tub using an air stone and the large rockwool cubes and i would germinate the seeds in the large rockwool already in place over the water and by the time the tap root hit the water it was ready for food. real easy way to do it. you could even make several smaller holes in your lid and do the small rockwool cubes. i usually had the cubes about an inch from the water until they sprout, giving them time to grow some leaves before they hit the grow water.

  • @drrezdc says:

    The best video on hydroponics I’ve seen. 6love the time-laps video.

  • @hazaqames477 says:

    Really good video. What I did to get the temp around 80F (when I keep my house at 70F while home and 65F at night) was to put a headless small-form-factor computer underneath my container. The heat generated by the computer keeps the temp where it needs to be for germination.

  • @ericjudd9088 says:

    New Subscriber – Thanks for solving my dilemma Jimmy! You make it common sense and easy to follow. Thanks for sharing! I started a couple of weeks before Christmas and found many YouTubers were confusing the issue even though they meant well. I’ve currently got some tiny tomatoes that popped out this week and about 17 more flowers to drop. I’ve been using the soaked paper method to start my seeds but have had great difficulty getting them transferred to the hydroponics. I learned from you that I wasn’t waiting long enough (about 7-10 days) for them to grow larger but at the same time they were getting “leggy”! As a medium, I’ve switched to cotton balls and will be planting on the cotton balls in ice cube trays tomorrow. I find the cotton balls wick up the water as well or better than rockwool and they are MUCH cheaper. I’ve been using my ice cube trays for about two months now. You’re absolutely right about using larger holes in the tray compartments. Once again, thanks for sharing! I look forward to seeing more of your videos!πŸ˜ƒπŸ›Ά
