I feel darn lucky. I hardly even told my wife my first year !. I bought one book the grow bible Cervantes and told nobody, and didn't google anything. I followed that book through one full cycle and harvest, following every jewel of know how offered, and voila !  never an issue to date 5 yrs later, always solid reps.  thanks jorge

O2 what is that Lol I have my grow room in a 4x8 walk in. I use circulating fans hung and my plants are on a schedule.. I nute once a week with dyna grow and I water every 2 days with my ph at 6.5 to 7.0..my room temps with out ac units and all that witch people use to keep it right are all ways 80 in light and about 68 in the dark.. I use pro mix for my soil and do nothing but let them grow : ) and there o so stinky and bushy.. ive topped once on all my plants so far.

can I convince you to augment with c02?  you have great numbers there in your room, nice to hear.

I ran a perfect room also for a year, then got c02, and now cant believe I grew without it.

I used "side lighting" on my very first grow too !..  Some bonehead told me to do it.. turns out to be a waste of resources, extra heat-for me.  Sure, the light will help those lower branches and buds form....the ones that wont get enough light in flower anyways, and should have been trimmed. I learned for the next tent full though, and saved the electricity/heat expense.

 

that big one in the corner vegged until she looked like this !

that's actually a post shoulda been in the side lighting thread, sorry.

 

In veg I use a badboyt5 fixture, 482 watts,2x4, 220v, 22-24 hours on

in flower I use a mix of metal halide and high pressure sodium bulbs, 60-100 dollar range each.

 

if you don't mind we can keep the c02 in the open, other new growers may benefit from the info?

 

51%2BM9haIbRL._AA160_.jpg I use CAP a controller similar to this one  to turn the light banks on and off at set times in both veg and flower, control humidity, turn off c02 generator if the emergency exhaust goes on and back on too(can be set to any temp/humidity setting, my room is sealed usually, unless it hit 83f) also can control ac. Its a one stop shop controller for me, flawless so far five+yrs.  google for directions/operations, pretty simple though, an asset for me.

Wow you got the setup grass. I have just been using my t5 hoods with different range of colored bulbs.. I like the bulbs that pretty much mimic day light.. they don't get hot and me growing in my walk in closet the humidity and temps are dead on all the time... I might have 200 dollars in my 3 hoods and bulbs.. and my growth has been beautiful...

what is "too" much co2? 

  gardens here are @ 1500pp,'s at lights on for 4 years. no fluff seen yet. I see fluffy buds when heat is too high, or par lighting is deficient. Maybe the added growth demanded more light, more resources, that were not available. co2 is not n additive plant booster, its a necessary life line to plants.

A plant will grow only to its weakest resource. I notice when I added c02 that my water uptake increased, garden temps did too, as did my nutrient demands, for the added metabolism caused, which will use 1500ppm comfortably. C02 will not fix an issue, and every aspect should be dialed in before adding another.

 

For instance, adding c02 to a t5/led flower lighting scheme will cause problems. Those lights lack the penetration and intensity to compensate for the added metabolism boost afforded by the augmentation with c02. The real evidence of this is often missed, as flowers will definitely look and smell good. A refractometer will show the issues of poor photosynthesis in the plant material all the way through its grow, signaling an inefficient "burn" in the process.  

 

Outside (ambient) air is roughly 400ppm's, and one might ask why is it fine outside, but I need more indoors?  The answer likes in air exchange. Outdoors every pant surface outdoors is bathed in refreshed 400 ppm every moment daily, keeping its usable c02 @ 400ppm full time. In an enclosed garden it is impossible to move enough air to accomplish this, even with fans, air exchange.

 

Trying this experiment will show these results quickly. I placed my c02 meter into a sealed bag with a plant, and increased the ppm to 1000 inside, with my breath !(yuck, plant says)

In only a few minutes the ppm's can be seen being used up by the plant. Of course plants will grow with just ambient air circulation, but a grower who wants to enjoy a fully expressed plant will need to fully provide every resource needed for the expression.

 

I grew in tents, using home air for a year. I thought it was the best I'd ever had, or could do. I added c02 and never looked back. I wouldn't do it if I didn't visually see the benefits of a "full plate" offered to my girls. Commercial greenhouses have employed the benefits of c02 augmentation for decades with huge returns for the investment. When my last generator took a crap, I overnighted another next day ! Heavier harvest, faster finishes, tight huge buds are my rewards. I read all about it in Jorge Cervantes grow bible, ends up being the best overall grow book I've seen, and I have most of them. highly rec'd by me, and the accomplished growrs that have assisted me.

 

happy holidays !!

I can appreciate that you feel that you've seen benefits from CO2.  I haven't.  And maybe it is because I use a rock-solid RDWC system....and have always been a believer that there is a way to offer a plant what it needs in low concentrations at a high recirculating volume rather than force what you want upon it in high concentrations and hope that it will respond.  I have run my DWC at anywhere from around 400 ppm to 1400 ppm and haven't seen any difference in growth rate....or 55 degrees temps clear through to about 110F....  and I've used CO2, stagnant air, and high volumes of refreshed air...and what I found was that HEAT made the difference.  How did I figure this out?  I ran my natural gas CO2 generator for a couple of months...had the flower room hitting 90+ degrees at 1500 ppm..and then shut down the CO2 generator and actually installed an electric heater to maintain the same temps....and you know what?  I had consistent results....So a high temp  flower room with high Co2 was producing the same as a high temp flower room with un-augmented CO2...with other parameters in the "ideal range."    Seems compelling.    So the anecdotal conclusion was that it wasn't the CO2 that made a difference.  It was elevated temps, which encourage increased nute/water uptake and therefore growth.  I have found that my best yield and quality occur in the summer when my room hits 110+ with lights on but I keep the RDWC nute temps in-line.  I wanted to be a believer in CO2.  So maybe it turns out that if your garden is already dialed-in, then CO2 won't help...but if your garden lacks in some area...then maybe the CO2 helps bridge the gap.  In my view, and based on my experience (which is kinda extensive), CO2 is somewhat of a misnomer and indirect benefit.

 

Try this some time.  Flower at 100+ degrees ambient temps while keeping roots under 70 degrees F.  This requires some work.   You might decide that it really isn't CO2 that boosts your plants after all....that maybe the higher temps encourage accelerated water/nute uptake and therefore growth.  Or maybe not.  I'm just telling you what I have seen work.  If this doesn't work for you, then by all means keep paying to generate CO2.  Myself, I see the value only in the heat, which accelerates metabolism.  If you provide a high-volume air exchange and high volume nute exchange then the plants reaches its own potential...and will absorb as much Co2 from the air and nutes from your solution as it needs to keep up with whatever amount of heat and light you provide.. This is just based on my own experience.  Yours might vary.  But I encourage you to explore this variance and try to determine if you're over-killing your effort with regard to CO2. 

 

I realize that CO2 has been used in greenhouses for many years, but let's look a little closer....There is a huge difference between using Co2 to try to augment growth of tomatoes and cucumbers vs. accelerating/improving the growth of cannabis.
