    I have learned alot on this hydro method so far... But on the next run I will be monitoring things more closely. I'm going to cut out 4 larger holes in each tray and use an insert to match the 4" pot. So then I will have a 8" hole to pull the plant out for easy inspections daily. Also during 3...

    Ya know... I really like your fan idea. Particularly the sucking air out of the tray vs blowing it in. There would be much more even flow thru the system. I just did an O2 test this morning. Levels at 5-6mg/l. About the same as last test. Its been two days since I added any H2O2 to the system...

    Purple Kush Wilting during dark (night) cycle

    Oh ya... Wilting during the dark period. I found out it was because of lack of O2 levels in nutrient ! When I added alot more air stones and big air pump. The problem went away immediately !

    Also... I will be getting another batch of clones next week. I'm going to be doing lots of testing on them. I will block the bottom of the mesh pot on some to prevent root growth directly out the bottom. The plants I'm dealing with now I blocked root growth out the side. A mistake at best ...

    Good luck with it man !! Its been tricky at best for me so far. I'm really only doing it this way because of disposal/ volume issues. If I were growing a smaller number of plants I would stick with clay pellets, Rockwool, etc. But kudos for you trying !! Uses H2O2 !!!! and if you can list your...

    Hey YAK !! Thanks again for the advice. You pretty much save me from disaster !!! Yes I backed off on the timings. After the top and bottom feed cycles. There is a 18min delay b4 restarting. And yes the temp dropped to 63-65 cycle. The replenish rate is tough to figure out. I think there are...

Cost was around 13k for...

    Thank you. And yes this is the first time. I used RW, Clay pellets, lava Rock b4. They all worked but such a pain to clean up and or dispose. Glad you think my roots seem ok. Yes there are a few white ones here and there too. I'm using a custom made light mover. It moves all my lights in...
