C-24 400 watt mh/hps yield

[GlaZed420]

I know im going to sound like "OMG i wanna grow pot cause its easy moron" Im not trying to sound like that at all im far from growing "great" pot but currently I have been growing outdoor I got 1 and 1/4 ounce's from a GDPxHaze seed that I got from a club in Oaksterdam. I have been waiting for the outside temps to cool so I could go indoor again. That time has come
My question is this, is it possible to reach 1lb with a 400 watt light aircooled via 4inch vortec/ co2, and ampell time for veg. The strains I am going to attempt in a ScrOG setup will be 2 SOL Blocheads, and 5 Soma's Lavender(I know her yield isnt great so I might consider a diff strain possibly Sensi Star) or a BOG strainm can someone suggest a high yielding strain that still gives you that connourseure taste, high and look. Can I have some opinions as too how completely hopeless my goal is and what is realistic. Im just trying to see if it is worth spending 120$ a month for something that I might not even get a half lb. Thanks much appreciated. GlaZed

Why is it going to cost $120 per month? I run my 400W HPS 18hrs during veg and it only raises my electric about $20 per month. On my first scrog I only got about 6 oz, because of heat issues the buds didn't tighten up. I expect to at least double that yield this round since I have solved the heat problem.

I grew C-99 last time, thinking of trying a different low smell satava but not sure which one yet. I like the C-99 very well so kind of hate to change.

I run a 4" fan in a C25 (smaller) and regret it. go 6"

 

[Guest]

and 400w in a full sized C24 = 8 plants, if you get pot sizes right, you should easily be able to do at least 1.5 oz per plant but thats only 3/4 oz... maybe with a scrog and/or co2?

my first grow in a c13 i only got 2 ozs, my second i went up to 5 ozs. running a 400 switchable and a 6" 256 cfm fan in an enclosed daystar ac hood. shooting for 6 ounces this time. wish me luck

 

[sensirocker]

i have 4 sensi stars under 800w no co2... im prolly looking at 1.5 oz a plant... im pretty sure sensi stars arent super high yielders.... have you thought about ordering some big bud seeds online? those should get you closer to your goal

It is not possible - although people have claimed such yields.

I agree - not possible.

400w with 4" is wrong right off the bat.

A 4" Vortex is perfect for 400w in a C-cab (c13, c22, c24, or c25) unless you have a hood with larger air-cool fittings. I have the 6", but only because my hood's fittings are 6". I turn it way down.

All 4" fans are not created equal. The Vortex fans are pricey, but the seem to move more air under resistance that other fans with comparable cfm ratings. They are also quiet.

There is a thread floatin 'round here somewhere.It was a 400 watt scrog set-up and they did get a pound or close to it.

The question is whether such a yeild is possible in a C-cab, not whether its generally possible. In a C-cab you typically have a few things working against you: (1) your square footage is less than optimal for the wattage; (2) the footprint of the cab is not optimal given the placement of the hood (this is more of an issue in the wider cabs (i.e. C22s, C24s, and C24s)).

In other words - the C-cabs don't offer enough (and the right) space to grow 1lb.

ahhhh.....ok....I'm tryin to find that thread as I'm not sure of his growing area.

Usually the people getting big yields out of 400w are growing in a space about a square meter large (or 9+ square ft.). I'm not sure of the exact dimensions of the C24, but I suspect its around 5 square feet and not an optimally shaped 5 square ft. either.

[Guest]

Yeah...you're right Pinecone....found the thread....he was growin 20 plants in a 20 sq. ft. area at 20 watts per sq.ft.

BTW - I have two grows in a 400w C13 (I'm resting on my stash now). The first one game out at 7+ oz of Grade A (plus trimmings) and the second came in at 9+ ounces (plus trimmings).

For me the most important thing has been getting good plants. Although the first grow was all the same strain (C99), the plants were not identical. Three of the plants yeilded around 2oz, while 1 yeilded around 1. With the second grow I started a lot more seeds and was in a position to be much more selective about which plants lived to see 12/12. I basically flowered the plants the best growth characteristics and it paid off.

I have a c25 with a 400w, and I agree that in a c25 it works. Anything larger (24 or 22) I would DEFINTIELY go 6"

I would still recommend the 4" Vortex with any of the C-cabs. The 6" Vortex is overkill, especially because most people will run a 6" to 4" reducer which limits the efficiency of the fan.

If your having problems keeping a C-cab cool with the a 4" Vortex there is something wrong with the setup (room temps that are too high or too much resistance because of the slinky ducting, too man bends, or insuffcient intake area). In your case - I suspect you are using another 4" fan. With a 4" Vortex you (generically) ought to be able to keep cab temps within a few (2-3) degrees F of the air temp in the room that the cab sits.

10 (2gal) pots will fit in a c-24. if you can get 1.5 oz per plant you can get pretty close. personally I have never gotten more than 3/4 lb from mine

My issue is the need for a larger intake (and two reducers to go fro 4" carbon to 6" cool tube, and back to 4" fan. And a lot of bends too, but thats not avoidable in a c25.

This is going to be a difficult task to undertake with the given surcumstances. if your looking to pull 1 lb your limited by too many factors, first of all is experience. even the most experinced growers who have grown dozens of crops would find it difficult to do what you want to. all i have to say is that you wont get hurt feelings if you dont set your expectations so very high, if you pulled only a few oz's off of your first try, then try and get your system down so that you can pull off 6-8 oz. that would be a big leap in production from your last grow. Good luck, and i hope it all goes well.
