feeding schedule needed to be used along with co2

Hi all and thanks for taking the time to read this thread and possibly offer some advice. So what I've got now is. A sog ebb n flow style in pots of rockwool flock. I flood twice a day with 1400ppm canna flores. Co2 is at 1500ppm through the day. I have noticed a jump in the ammount the plants drink since using co2 which is making me rethink my feeding schedule. I wanna be able to flood as often as possible to ensure roots are constantly aerated. What I wanna know is who's running co2 and what feeding schedule your running?

some would flood much more often than twice per day. try 4 times. in growrock you can do even more, like 12.

Is growrock like hydroton? And I very much doubt I can get away with flooding more in the rw. My pots r 6x6x10" and my sog plants struggle to drink 2 feeds per day as it is. If the growrock you mention is a repellent medium like hydroton and can be flooded 12 times a day then that's gonna be my next change, root aeration would be awesome with frequent floods like that

yes hydroton is a brand name for grow rocks, or more specifically, expanded clay pellets. yes you can flood as often as you want and aerate the rootzone. they are recyclable, and the best growing medium I ever used

How dyou clean em? In the washing machine? Tbh expanded clay pellets was allways gonna be my next move. Just started another thread cos I wanna know if you can transplant from an aerocloner straight to pots of hydroton without the use of a cube. I figured I'd just fill half the pot with hydroton and place the cutting in and then gently surround the roots with more until the pot was full. What's ur method? U running co2?

I don't run CO2 because to benefit from it, you need to perfect everything in your room or else, it is 100% lost investment. also you need to get a fully automated system with controller and regulator etc... which is costly.
you can transplant from aero to growrocks no problems there.
to clean them, I have used many methods before, the best and easiest I found is using H2O2 35%, I just remove the rootballs and whatever root structure that I can then I flood them with water and a high dose of H2O2 and leave them for a day or so, then I drain and flush them thoroughly. I have tried other methods like spreading them and waiting for them to dry but it requires a lot of time, also have used the oven to change the roots to ashes, but this method is overkill, although it is most effective and almost perfectly removes all roots, it requires work, and oven gas, it is not necessary.

I toyed over the idea for about 6 month before I went for it and It has turned out to be well worth the money. I've bought the echotechnics controller with the infra red sensor and I've got it hooked up to thier temperature fan controller. Also have a dehumidifier on a hygrostat to keep rh at 50%. Room temp is 26c leaf temp is 29c. Air is changed all through the night then temp only rises far enough to warrant air exchange twice a day. I know I'm wasting that co2 but it works out cheaper in the short run to waste some co2 due to cooling the room, as apposed to installing and running an ac unit. After 3 cycles of getting everything dialed to work with co2 I'm pulling an extra half ounce per sog plant. Which works out at 50 ounce a month. Which is all the proof I need to know my investment wasn't a loss. But ur right tho the automation equipment cost me nearly £1000. I remember getting it and it was just 2 small boxes with wires, I was pesimistic to say the least. But its been working and i can't c any reason why it shouldn't in the future aswell

okay then, i didn't know that you have your room dialed in, it is matter of priorities, my priority is not maximum yield, because i smoke much less than what i harvest so i just grow some bud with ventilation. If my target was maximum yield, then I would go with vertical setup SOG and definitely a CO2 kit

Ohhhh here's a vert guy. You ran a vert system before? They seem very complex to me and having water higher than most of the power seems like an accident waiting to happen. Each to their own tho, no 1 style/system is right for everyone.

I bought the pipes for a vert system, and have everything else but I never really built it. my plan was to put pipes in columns plants in small 2" rockwool cubes sticking sideways and feeding with nft drippers on top of every pipe. I believe that vertical will yield more than regular growing once done right

you said if u have co2 and everything needs to be perfected or 100% loss? like what do you mean? what needs to be done what way?

well, room needs to be sealed, plants must be in bottom of the box which you are supplementing with CO2 since it is heavier than air, you will need ac since it is sealed, and most importantly, you need to raise the ppm of CO2 to 1500ppm and maintain it there, which needs a good expensive kit without which it can't really be done. Also, if you still are making mistakes and not getting the most out of your grow without CO2, then you still have many things to improve before considering CO2. it all depends on how advanced you are in growing already. good luck

i have a sentinel controller with co2 tank and regulator ac and everything just glad thats all u mean.
