400w Club-Show Off Your 400w Pride And Joy

[SenseiGT]

50W/sq ft. is a good baseline. It is not a minimum by any means. There are very successful grows at 40 and the plants will grow at 35 but they will be airy buds rather than tight nugs.

You have 40 sq ft. To make that whole area a flower chamber it would be 2000W. Not sure how much you pay per kwh but that would increase my bill over $100 a month. That does not include the fans, pumps, timers, etc.

Given that same space I would section it off with a simple 1x1 frame and panda film (black and white plastic sheeting available at hydro store or online). Make a 3x5 bloom room and a 3x5 veg room for mom and clones. Hang a 600W HPS in the bloom and a T5 fluro or lots of daylight CFLs in the veg chamber.

Perpetual goodness

thanks for that suggestion, im so gnna do that. like, rly, look out for my journal within the next week.

edit : whats bette rto build the tent out of, wood or pvc? in terms of holding up my 400w which is quite heavy since it has no ballast, and i plan on having exhaust in the tent, sooo. idk. tent out of wood or pvc?
and yes perpetual goodness

Either will work fine. The commercial tents are made from PVC. The 1x1 wood frame would do the job and would be easier to attach the plastic. Check out you prices for material in your area. You could also look online for a pre-made tent. You may not find one matching the exact measurements described earlier. Most of the pre-made tents are square. 4x4 would be the closest to your desired size.

Yeah I need some Mg in my plants but the vegging feed I got doesnt have any So could I feed my plants with some of my flowering nutes to give em that kick of Mg they need? Its floranova

Buy some Epsom salt and add it to your feed a 1/4 to 1/2 tsp / gal.

Not sure if this slack ass town has Epsom salts would t he flowering juice work?

 

[bleezyg420]

most super markets carry epsom salt.

$1.29 at any supermarket or pharmacy. You can use the FloraNova Bloom if you want but be careful not to overdo it. If you do that I recommend using just the FNB rather than trying to mix them.

How close can I actually put 2-3 inch plants to a 400w light? I dont want to fry them and I usually keep them pretty far away, but I dont think that there close enough.

my 400watt halide will fry my younger plants any closer than 18" and i dont have a cool tube... but you can put them up there and just keep your eye out on them


Peace

I can get my 400 watt HPS about 8" away.... although I do have to larger fans blowing though the canopies of my plants......

 

[amcgin02]

Has anyone here ever grown autoflowering plants under a 400w, and had good results?

 

[Douche Nozzle]

I use an electronic probe cooking thermometer to moniter my temp. It goes from 0-500 degrees. I hang the probe at the top of my plants and can set the alarm for whatever I think is too hot. The display for the probe reaches the outside of my closet so I can see it anytime, light or dark cycle. No guessing.

 

[2smoke4bud7]

cool i just purchased a hygrometer and shows the inside and outside temps max/min and humidty pretty neffty
dont have to zip open 3 zippers to find out the temps

 

[Tanis83]

dammnn sickness!! lol how many plants did you have in the room while flowering this lady??

the most ive yeild per plant is a little over 1 oz -_-
but only 1 grow under my belt.

cant wait for another month my 2nd and 3rd grow are under way!

 

[SlikWiLL13]

i flowered that one and theres two more just like it at 3 1/2 wks. i have room for 4 of these but havent had a full load yet. 12 oz's would be a sweet harvest from a 400w!

 

[Tanis83]

Here is my cabinet again... I had to get a new fan and tie down my ladies... they are getting way too dam big!

 

[Mr85SS]

some great grow in here from 400's...specially caddys trainwreck & crimea blue...kudos for that

Thats why they make fan controllers. A stable 7 degree drop during the dark period is beneficial. Unless you want to stand by your op and plug and unplug your exhaust and intake fans to keep the temp stabile. Might as well drop the cash and have electronics take care of it. Just plug dial and go. You dont have to be around to hear a beep, not to mention those arnt accurate for room temperatures what so ever .
