250w HPS Club And Help Guide

I have been wanting to set up two grow spaces but don't want to dish out much more cash. I came up with this way to ventilate two 3'x3'x5' tents, one which would hold my 250w and one that would hold ten 23w cfls, using my single 6" inline fan rated at 400 cfm and my one carbon filter. The filter has a capped end so I can't put it in the middle of a duct run. Instead I will build a small box that will hold the filter and the inline fan will pull through the filter and push through a short duct out the window. The box itself will have a 6" duct entrance. Here will be a 200cfm booster fan blowing into the box. The fan will be hooked to a y split. Each Y split will be connected to a duct that runs to each tent. The tents will have 10" passive intakes and small oscillating fans.

Which tent are you using? My 3x3 GL120 has 8 inch ducting sleves for intake. Either way with a 400cfm fan hooked up to 6 inch ducting, I think you would be fine running 8 inch intake. But that's just me :).

I'm really wanting to try scrog. I'm trying to work on my perpetual grow. I'm keeping at 6" just to be safe so I don't pull a stoned moment lol. I did that once and my girls hated me. MJ is an amazing plant as how she can be almost completely dead and then produce an amazing crop.

Why are you wanting to drop your rotation?
I'm wanting to drop my rotation cos I currently 2 plants in week 6 flower, 3 plants 1 week behind them, another plant 2 weeks behind that, and then 3 plants in veg begging to be flipped, and another 5 in week 2 or 3 of veg under CFL's. I am making up batches of feed every single day, 2 or 3 different ones at a time some days, letting them stand for half hour and pH testing, then slowly watering, and carefully replacing under the lights. If I just have 2 plants in the 2x2 tent in 2x1 scrogs, 5 weeks apart, and then slow veg in the CFL room, that should be easier, and provide enough smoke, at least an ounce a month.

And hell yeah it's an amazing evolutionary feet, I have forgotten to water one of my flowering plants, and came home tonight 10 minutes before lights out to see a very very wilted unhappy plant... and I'm gonna enjoy watering it tomorrow, watching the branches start to raise form the lower ones up as the moisture is drawn up through the plant.

On the plus side, I think that I have convinced my wife to let me by a 3x3 tent and 400w to flower my veg plants now, cos otherwise i'm gonna be in a bad way for space

Haha I have done that a few times man. I just gave my girls a water this morning 2 of them with molasses. They were begging me for a drink this morning their last watering was Sunday im running on a 2 day cycle. They get watered Sunday morning right after lights on and then Wednesday again in the morning. By Tuesday evening they are starting to beg me but hold off since I don't want to water shortly before lights out. Has been working well for me.

I've been trying to convince my girl to let me get another tent lol. Hoping I can convince her.

I am actually building my own tents with 2x4 studs and 6mm b&w poly. I guess my main concern with this design is "will the 400cfm fan still pull sufficient air from the tents or am I loosing a lot of power by having the fan in the box and not directly connected to the ducting coming from the tents?"

hello boys n' girls !
although I wasn't planning on being the '250w user' - the store from which i ordered screwed me over,and instead of 400w sent me the 250w-which is a bit awful,considering
the dimensions of the grow tent(100cm x 100cm x 180cm),but my bad was in the first place,for not ASKING them about the bulb, 'cause I figured 'hey,it's a grow shop,ofc they'll send me 400w with that grow tent' ooops...and on their site,it states NOTHING about the bulb,just that it goes with the tent.clever eih?
that said,
i'm still loving the results,very underestimated lamp,specially 'cause you can really,REALLY place it close to the tops(i go as low as 7-10cm)

here's some pic's

unknown strain,some wonderfull weed i smoked,and saved the seeds a while back...it's the begining of the 4th week on the 12/12 regime,the girls were about 40 days in vege,prior to that
LSTed,flushed couple o' times,and fed with an INCREDIBLE organic fert,actually microbacterial organic fert
more info in my journal-here-
https://www.rollitup.org/grow-journals/562564-growtent-250w-mh-hps-unknown.html

be free to comment on the photos,I think I'm doing fine(first time indoor grower btw),and I'm def. subscribed to the club!
peace out!

We always like pictures of budds in a box. It pretty packed in there, have you got some sort of air-flow for it?, don't want to get this far and end up with budd rot, belive me! :)
Hettyman, I have a small fan blowing constantly. The temp is 74 F and himidity is at 45%. 3 days drying. Feels goo, looks good, smells good.

cbtbudz, I hope it does better than a qp. I had more than a qp last year using CFL's. I will be happy with whatever I get, cause it is more than I have at the monent.

Giggles26, Thanks for the info about qp. Make sense ..qp..I think I shoud find an abbv. pg., and learn weed speak :-)

Hey can any of you guys recommend a good smaller oscillating fan for use in tents?

The one I have now is just to large and is taking up to much room. I literally think that I could get another 2 plants in if I could find something decent to replace it.

My tent is 3'x2'x5'. Just let me know what you guys think.

ok well i have had a fun day, decided im gonna scrap the scrog. in fact i already have lol. got myself a 50ltr bag of plagron lightmix, topped my ak48 to give my amnesia a chance to catch up and im planning on mainlining the ak48 as it looks awesome. cloned the top i cut off so i have that in the cupboard as well now. missus is gonna go mad. went from 1-2-3 then 5 as i have an ak47 auto germing as well which im gonna have to train the shit out of as the last ones got 3' and a bit and i wanna keep them all low to spread the light better as i only have a Lumii Mini reflector. probably gonna be vegging for at least another 3-4 weeks to help with the training i need to be doing.

btw what a bargain, found a nice little tucked away hydro shop near where im working and they sell all the plagron 50ltr bags for under £10, the light mix is £8, allmix is £9 and batmix is £9.50. bargains lol. bear in mind im in the uk i walked in and the fella behind the till was rolling a joint on the counter, should have seen the look on my face lol.

That is cheap, i'm paying about £14 for a 50l Light Mix Biobizz.

lol, do you remember me saying about being told to drop down to a 2 plants by the missus, which I converted to 2 plant rotatoin of 6-8, which soon went out the window...well she has finally caved and I am ordering another tent and 400w light for my next 8 plants, which are all gonna be larger then anything I have previously grown. I am so fucking happy right now :)

Haha yea man I remember you saying that. My girl is telling me to get more plants in the ground lol.

I wish I had the extra cash to get a new tent and light ha. But before long im going to have to get a new setup cuz I've got to many going in diff stages right now.

You could always share with me lol.

Plus side I got 2 new girls that popped today! yahoo! Its gonna be day tomorrow.

Need to get some more seeds ordered.
 
How far should my 250w MH bulb be from the plant in first weeks of vegging?

edit:
What do you guys think about this plant, it was trasplanted yesterday and I started to give nutirents in mild dosage. Leaves look king of down, is it overwatering/overfeeding?CIMG1351.jpg
