150w HPS Club and Resource Guide......

[rootidec]

I cut big front fan leaves, leaving some on the back. I use thin rope to tie shoots toward the light, and supercrop the top toward the light when it reaches the ceiling.
This occurs mostly between the 3rd and 6th week from seed.
I stressed plants though... they'll take more to finish.
Vscrog should stress plants less, but I have no experience.

 

[veclo]

cool, ill read up a bit more on vscrog, cant wait to get started!

thanks for now, i'm sure ill have more questions down the road

Like i've said before my cab would be in the basement, where it stays relatively cold even during the summer, i'm thinking more of the lines that it'll be too cold in there rather than too hot

Depending on your latitude this can be a consern, and not just in the winter. Cooler temps can stunt growth. Especially root growth. There are several ways to alleviate this. The cheapest/easiest I've found it to put a reptile aquarium rock under or near the bottom of your grow space. They stay @ a constant 72-78*.
You're right in your thinking that not all buds, and not all sides of the buds will get the same amount of light in a vert grow. In my experience, this really isn't a big consern. Before you start pulling out fan leaves (a major source of energy for your plant) just do your best to arrange the bud sites evenly/equally around your light. I tuck/push fan leaves behind the buds as best I can.
I also grow vert, and have never had a fan blowing up @ my bulb from below. A few fan leaf tips get singed, but as long as your temps are under control, your bud is 4 or more inches from the bulb, and you have good air circulation/movement inside the cab, you should be just fine. A strong argument in favor of growing vertical is that it significantly increases your grow space. When using such a small HPS bulb, it's very important to keep as many mini colas (bud) as you can with in 4-12 inches of the bulb. In a traditional horizontal grow a 150 can cover roughly 3 sqare feet of area. When you hang the bulb vertically, you can cover a (vertical) tube/pipe shaped area 10-12" high with a radius of 8-10" which equates to an area of 4sq ft or more!
Hope that helps.

Great wall of text vintner, definitly solved some of the problems i was visualizing in my head. : D
It seems vert growing is def the way to go!

Amazing info guys thanks a lot.

Regarding the intake holes, what other means do you know to cover the hole? My closest neighbour is roughly 100m away so I don't think ill need a carbon filter for the smell. The intake holes sohuld be at the bottom of the box i assume?

Yeah, I'd put the intake down low.


Are you planning on cutting the cab floor or the side/back whatever?

I've seen in some journals that people put an ac fan under the vertical light to push the hot air up, do i need to do that even with an 150w?

It'll help circulation in addition to cooling the bulb.

By the way, i read somewhere the MH lamps are better for vegging, is it worth buying another mh lamp or just go with hps from seed to harvest(since i will be doing the 12/12 technique)

It's up to you. MH might be the best veg lighting but I get away with blue or white CFLs. Lots of growers veg with HPS.

I'd like to try rootidec's pll lamps in veg. Twisty bulbs are ok but the rob headroom.

 

[veclo]

The intake holes will be on the side, ill take some pictures when i get a chance. And i'll go only with an 150w this time, to keep it as simple as possible.

Could you suggest something that would cover the light from the intake holes? I don't have to get a carbon filter, since im not that worried about the smell.

hi veclo,
Disco already suggested you "darkroom louvers" in previous post

A couple layers of this might also do the trick. It comes as a sheet (from Lowes or HD) that you can cut to any shape or size needed. Although it's a carbon filter, it does very little to eliminate oders. I use it as a filter & light trap on my passive air intake.

Unless you have a medical card that allows you to grow leagally, I'd give careful consideration to your decision not to run w/a carbon filter. What are you going to do if you need to have a repair man in to fix something in your basement when you're 3 weeks from harvest & your plants are reeking to high heaven? Or unexpected & nosey guests?

 

[veclo]

You are right, i'll do some reading on odor control, i have access to fresh air in my basement but its near the ceiling, gonna have to work something out.

 

[webecat]

Speaking of odor control, my DIY scrubber and the new one I bought on Amazon both only keep the smell in a room (barely). I really worry about people coming in my house and smelling it, so what's the best scrubber? Or other odor suppresser for my cab? maybe an Ion generator?

man i wish i needed a carbon filter i havent grown anything that stunck the house up.

I've never had a problem w/my DIY can filter which I made using this thread. I've been using it on & off for 3+ years now & have never changed the carbon
My initial thought is that you're probably using the wrong size fan or filter, but you'd have to supply more info to get a more acurate assessment & help. Cab dimentions, what you use for lighting, ventilation & air movement, average temps (lights on & off), & of course exhaust fan & filter sizes. Are you pushing or pulling air through the filter?

 

[dddaver]

A while back MH was discussed for vegging. I think that depends on the ballast you use. My magnetic ballast (I'm on my second one) will not run a MH bulb, while there are digital ballasts available that are switchable so allow you to do that. I saw one on here the guy said he picked up from Alibaba? for $70. So in a word, it's ballast dependent if you can use a MH in your HPS set up.

This is the cab Vintner, flower is 30w x20dx 48h with a 150 hps. Veg is 16w x 20d x40h with 3 th 6 clf's depending on what I'm doing atm, roughly 26 cubic ft. flower temp is 80 to 86 veg is about 10 degrees less. humidity is around 60% which I suspect could be the problem. the fan is a 100 cfm axial pulling through the scrubber. My DIY is 12" long with a 3" core and a 5" O.D for a 1" bed of aquarium carbon packed tight (not shown). The Chinese scrubber had no specs and lets more odor through so I got what I paid for. I have the fan shown and another smaller one in the veg cab so the air moves well.
I have already bought another cab (same size) but new not used. I want to work the bugs out before I build the new one. It will be split down the middle since I found a ebb and flow tray small enough since that's what I built the cab around.

 

[vintner]

That's a great lookin little cab webecat & thanks for all the info though I did neglect to ask for one more tid bit. Do you know the make and modle of your exhaust fan? How about the static pressure rating? (though that info is harder to come by.) What did you pay for it? One should definitely not skimp an exhaust fan!
As long as the fresh air intake hole(s) for your flower chamber are @ least twice the area of the exhaust port, my only suggestion would be to play around w/the location/orientation of your fan/exhaust port & scrubber to try to eliminate that bend in your ducting.
Hopefully some other old timers will chime in w/thier thoughts

 

[DiscoBiscuit]

webecat, try cracking one of the flower doors open about ~1". (A screwdriver handle works pretty good.) Wait about 20 minutes and see if the temp lowers a few degrees. If so, you might benefit from additional intake.

Axials don't hold up that great against static pressures of ducting and or scrubbers. Two of the same fan stacked together won't give additional CFMs but might withstand static pressure better than one.

 

[darkvade420]

WEBECAT : Thats looks like its going to harvest close to 3 oz man thats a great grow .. how many plants is that?

 

[webecat]

Thanks for the input DB and Vinter both. I bought an SP fan for the future cab and I ordered a phresh air filter. I thought maybe I should throw some money at the problem, and I've heard a lot good about phresh filters. The smell is only in the room I'm growing in so the whole house isn't smelling at least .
Thanks darkvade420, I have learned a lot from my first grow and sure I will be able to tweak is some. 3 zips would be sweet, blue dream has a good rep and it's pretty frosty, I'm ready to sample. There are 4 plants in there and I let them veg under the HPS to long so not as even canopy or enough big buds as I would like.
