newbie setup. venting, lights, air flow?

[3289275]

hello. hi. hey. etc etc

 

thinking about starting a grow. tried in the past and failed horribly (jumped in without doing and research + wrong equipment) . probably wont do it to lack of places to hide but if i do. 3 main questions.

 

budget quiet vent fan?

and

400w mh bulb for a digi ballast?

and

6"  venting for a 0.80x0.80x1.6 to much?

 

been looking at this thing for venting but its growlush. no reviews. no nothing

http://www.growlush.com/productcat/grofan/#prettyphoto[group]/2/

 

it is current being sold as part of a complete package which is dam tempting for 200$

in the end its all about the noise. the less the better

 

next issue is lighting. i read here maybe? that conversion mh bulbs were ifish for digi ballasts and thats all i seam to be able to find. its all a little confusing. the ballast is a 400/250w nextgen digital. so any suggestions would be very much appreciated.

 

and lastly i was going to go for 6" venting for the tent. its only 0.80x0.80x1.6m and if i did the calculations right its cfm needs are only around 40-50 so 6" seams to be overkill but with summer coming i thought the extra air flow would help fight the heat.

 

all in all im still up in the air about the whole thing. on one side of the coin a family history of cancer, failing health and just so dam tired of opiates as the only legal pain solution. on the other side i have nosy in-laws that are happy as hell if you drown yourself in beer but mention pot and your the lowest of the low. already lost many a nights sleep stressing about it. getting to the "fuck it!" my life my home consequences be dammed stage

 

also want to keep my costs pretty low. if in-laws, neighbors, little grey men in saucers, whoever rat me out all the shit i buy is added to the boys in blue retirement fund so buying the best of the best just seams silly. that being said even if i don't grow the greens i will have a winter garden for out of season vegetables and such so everything will still be put to use

 

anyways thanks for reading sorry if its a bit ranty and any suggestions and help would be gladly appreciated

I haven't done a indoors grow for a few years now, but it sounds as if you're pretty well on the right track apart from a couple of things you might want to consider.

 

As for the GroFan, it's lacking a vital bit of information in regards to it's potential output (maximum air flow). Without that info, it could see you fall short of your requirements. Because as soon as you start connecting bits to it and bending ducting around corners it will create a fair bit of drop off in air flow. Also, it's pretty hard to get a silent fan/ventilation system because either the fan and/or air flow can create significant noise. This is where you'll require a bit of nous to figure out where to have your outlet and how to silent it somewhat to a level you find suitable.

 

For the light. I ditch the idea of running a MH bulb because the spectrum they work in mostly suits the vegetative stage of plant growth. Get yourself a HPS bulb setup as you can cover both vegetative and flowering stages of plant growth.

 

Goodluck with it all, 328... As I can fully relate to opiate BS we got to deal with. Once you find the right strain that works for you, the better off you will be.

thanks for the reply. i figured there would be noise no matter what but the mixed flows seam to be on the lower end of the decibel range. the less initial noise then the less i have to tinker to cover it up. i guess i could sort it out with a fan controller as well just to much of a tight ass the fork out the extra cost. going for the 6" was my idea of dealing with the any air flow problems. my tent only needs a 4" ,if that, and having the extra size (in my mind) would give me room for the filter and what not without losing to much output. possibly failed logic on my side.

 

this

 

compared to this

 

is a world of difference though.

 

 

vegging is why i wanted a mh bulb. im happy to switch between mh for veg and hps for flower, my ballast can handle both. digital ballast friendly MH brands are what im after. tried googling it and all i get are store pages. its the conversion/retro fit thing thats confusing me. i was looking at the sunmaster dual spectrum hps though, one bulb for both cycles will cut down costs

 

im starting out on the kc brains cheap train. if i can run them from seed to flower without any major fuck ups then i'll invest in a better quality strain

 

thanks again for the reply.

 

have a good one

OK, so here's my 10c worth on your MH vs HPS.

MH is going to give you 'better' veg growth but being that you are growing in a confined space that 'better' growth gives you a greater space between the nodes, where the buds form. I grow indoor, not so much a confined space as yours but still indoor. I use HPS from start to finish. This reduces the space between the nodes. Now I grow SCROG and I don't want large spaces between the nodes. Using HPS reduces this, sure it takes a bit longer to fill my grow space prior to turning 12/12 but it means I have more nodes and thus more budding points.

 

Hope it helps

I always thought the hps would cause more stretch then the mh. I'm flooding myself with "how to grow" videos and one of the few things they all agree on is mh for bushy plants with tight node placement. Hps during veg will only cause the plant to stretch and cause huge gaps between nodes.

 

I'm not saying your wrong. Your a world ahead of me in terms of experience. Just trying to process all this information. I was going to try a scrog, it looks like the best option for a decent yield. The Sunmaster dual spectrum hps is on my radar right now and investing the cost of a mh into a timer that doesn't fuck up half the time feels like a smarter option

You are right, Merl1n is wrong, MH does reduce the distance between nodes
