Answer by `b0n
do not put much pesticides. if you can manage, do not put pesticides. pesticides poison the soil. that’s why nutrients in the soil will be gone, because the soil will be poisoned. just a tip, do not put pesticides, and put fertilizers(the organic ones).

  1. Thank you for the video.
    I also have some tips to grows up to 10 x the plants, in half time, with more healthy plants, while the “fish” execute everything…”

  2. Yellowing leaves on tomato plants, means need more iron in the loop.

  3. I use well water, but I have a Reverse Osmosis System setup.  I would recommend RO water to anyone, not just wells. And let your water sit for a two days if you have city water and chlorine and add a air stone and air pump to get it out bettet

  4. My tomato plants seem to be burning off?
    The leaves start to die and then go really dry and crunchy in a matter of days..
    Any suggestions?

  5. Hi, how do you star the tomatoes plant?? Just put the seeds in the growbed???

  6. can you talk about costs?
    thank you

  7. Of course it will man. I won’t work with Aloe Vera, since those don’t need water everyday, once a week or so is good. But if weed needs to be watered everyday or whatever, then, yes, this should be fine, since it aint a water storing plant like cacti and succulents such as aloe veras. Peace.

  8. No, you cannot grow weed with this water based system the roots will develop water rot, or become water logged

  10. THIS IS SOME REAL GANGSTA SHIT BRO…WILL IT WORK WITH WEED????

  11. foobargorch, these particular goldfish are fed Omega1 goldfish pellets.

    Thanks for watching

  12. What do you feed the fish?

  13. leebog31. You do not want to use tap water from city water source. Sometimes well water can be used, but test it before use to make sure it is safe. You want to try your best to not add too much water at one time and/or water that has floride, chlorine or other added elements as this will upset the bacteria and cause fluctuations in PH and balance over all. I have never tried growing potatoes in my systems, but I know carrots can be grown. Thanks for watching.

  14. Can you grow anything like potatoes and carrots or just plants that grow fruit upright?

  15. I’m new to this. I want to make one. I was wondering kind of water do you use? You get it from the lake or is it fluorinated tap water? The tap water you have to change the PH levels and stuff right? Thanks.

  16. 44redman1- you most definitely eat the produce, and doesn’t kill the fish.

  17. molinobeer, They create effluent-rich water that is broken down by beneficial bacteria resulting in food that the plants can utilize. ( Fish – Ammonium - bacteria – nitrites – nitrates – plants).

  18. What do the goldfishs do in there?

  19. Thanks, padkisson. @ neogardener, I don’t have much problem with pest. Being that the system is outdoors there is some pest, but not like my plants in the soil garden. I use food grade DE around the base of the system to keep a lot of the problems at bay. This system and another greenhouse system I have are using goldfish, but my test system uses perch and tilapia. Just about any fish will work. It is truly amazing how well the plants grow in these systems. Thanks for your comments.

  20. Your system looks really impressive. I just want to know if you have had any problem with pest infestation so far since your system is placed outdoors. Are you just using gold fish in your aquaponic system? Your tomato plants really look so healthy. Please keep us posted on the development of your plants. Thanks.

  21. Very nice job. That is quite a system!!!

  22. Check your soil. It may not be very fertile. Make compost from organic vegetable wastes from your kitchen as well as the dead flowers and leaves from your garden to enrich the soil.

    Procure good quality seeds and plant them in moist soil in a small patch. When the plants are around 3″ tall transplant them in your back yard in rows at a distance of about 1.5 to 2 feet. Transplant in pairs – with means two saplings together. When they are around 9″ tall, plant a strong bamboo or any other stick next to each couple for support. Tomatoe plants cannot bear their own weight and tend to bend over towards the ground. the stick will provide support. When the plants flower and begin to fruit, tie the plants lightly to the sticks.

    Regarding pesticide, spray neem oil mixed with water. Shake well before spraying.

    Water every day but dont flood.

    Good luck with the tomatoes!
