400watt 1 pound???

here the idea, ima build a 5ft room 5 5ft wide with 1 400 watt hps for 12 plants an have 2 fans 1 pulling out hot air and the other pushing fresh air in. idk about the strains im gonna use i guess anything i can get my hands on but im just wondering can i get a pound with this setup and using mainly foxfarm nutrients and mollases????

No doubt that is a strech with only 400 but it is what it is. Just make sure you get some good soil also like Happy Frog.

Go 600 watt, its pretty hard to achieve 1g/watt and with a 400 watt even if you achieved 1g/w you'll still come up short.

I've always heard that hydro produces less yield but higher potency... is this rubbish???
Its the other way around, Higher yield less potent (is what they say)

Actually its higher yield I use to grwo hydro and you just get overall rapid growth. Now the end product depending on the strain can be hot or so so. Some strains were meant for hydro others are not. Potency nah depnds on grower and strain bot really if its hydro or soil. Now if it was outdoor and indoor your comparing..Indoor grows have a tendeency to be more stronger than outdoor ones.

That would be tough to do but not impossible ive seen some really awesome journals from a single 400 watt hps.

ive babied a sage plant for about a month now its at 9 weeks today and i began flower last night. i just bought a 400w hps setup also. with a vented hood. what you might want to consider is a vented hood.
i took off the plate to my ac vent. bought some 6" ac ducting form home depot, slipped it into the ac hole in the ceiling and ran it straight into my hood. ran more ducting out of the exhaust side of my hood pointing towards the plants. running my ac at 76 leaves my plants at a comfy78-82 after cycling through that hot ass hps. pretty efficient i'll take pics.

putting actual cooled air over an hps bulb can cause the light spectrum to be different. it is better to remove the heat and then cool it.

this puts me at 6 weeks into my first grow :) if youve got a little extra income, the best advice i was given is to go ahead and get yourself good materials and suplys.
definately fox farms happy frog soil ive had 100% success with that and feeding nutes.

the ac unit actually alternates only running for about 15 minutes every 30-45 minutes. and i do have a fan built in that runs all 12 hours it does.

i'd suggest scrogging under a 400...you can easily achieve 6 ounces under 400 watts scrogged with two plants. and with a SCroG it will optimize the light off of a 400

Your goal is possible, But is this your first grow? If so 200g would be respectable. Fox Farm nutes are good for beginners, but I don't think they can hit that goal. Scrog for sure, even with that many plants. Good Luck,

yeah man you just have to make sure you feed them everyday 4 times a day at double strength that way they get big and strong..kinda like the old pop eye show. just take a toke and imagine that..wait why do that when you could actualy do it! instead of feeding them with water give them spinach smoothies and just dump all of your nutes directly on the center of the plant youll be set bro!!

also if you really wanna increase your yield dont do anything i just said

Wow! thats news to me...and my girls. Seems to be the other way around here. My light config. draws fresh air from outside and exhaust back to the outside. In the summer it is drawing hot air but in the winter they are drawing -30 C. or colder. The air is so cold in the winter that in the morning just before lights on my first 2 hoods closest to the intake are all frosted up, including the bulbs. Never had an issue, no popped bulbs, nothing but goodness, in fact the cold weather brings bigger bounties consintently
