When growing plants in containers and hydroponic systems the grower is responsible for all food the plants receive. If the grower does not know exactly what’s in the plants medium the plant could show countless signs of deficiencies. From understanding the differences between over fed and under fed plants to knowing how to fix complex plant problems Matt is here to explain some things he thinks might be useful when your plants just don’t look happy. We grow four big hydroponic plants under the same grow light. Three in 5 gallon fabric pots filled with coco coir and perlite, and one in a Grodan Unislab — stonewool. Now you can find out how they turned out!

    how do you get up under canopy to treat for bugs when it grows dense and is in a trellis net

    if you top feed rockwool, there is never a need to flush…because every fertigation rebalances the cube…five times daily.

    also, why a mini slab instead of putting the plug directly into a hugo? it may have performed better in the ebb and flow with the other pots.

    Would you rather use a Soil Mix Root pouch easy2grow gravity feed system, or a top feed system. Both with a organic nutrient mix. I cant decide, what to try next.

    Cat-ion, not "cayshun" as in vacation. As a professional, it makes you sound less knowledgeable. Whereas with a hobbyist without chemistry experience there's no need to quibble.

    I know you gave a disclaimer on everything here being anecdotal in terms of results, but your enhanced yield seems to be more of a result of your rock-wool plant being in the front, your video shows the rock-wool plant receiving more light from the side and air-flow as well (and you subconsciously fawning over it more during the growing process). Your logic that the smaller root-ball indicates more yield because it doesn't need to look for nutrients sounds like a classic case of correlation is not necessarily causation. My understanding that the larger the root-mass the bigger the straw to draw up nutrients, commercial industry prefers rockwool not for yield but efficiency and ease-of-transplant and square footage utilization.

    where are the roots? I see people growing huge plants producing heavy buds in 6x6x6 rockwool. How is this possible if there is not much for root growth?

    What's the point of the net when those plants are not climbers?

    Everest! How are you doing today? I'm building another grow room. I want to use 4 1000w DE lights in a 13×9.5x7ft tall flower room. I want to run a sea of green grow because of the short ceilings. I was thinking a top feed system to 4 4foot flood trays.
    What would you do?!

    Great vids…just FYI it's Cat-eye-on, as in ionic not "kayshun". Ions, anions, cations. Keep up the good work!
