Big Buddahs Cheese 400w MH/HPS

Hey guys, this is my first grow ever. I've done a ton of research but you don't really know until you do it so feel free to leave all the suggestions you can. I'm not set in stone on anything. Here's what I got.


The good stuff:



A basic shot of the grow room, I took it when we were moving in so everything's much cleaner now. The dimensions are 2ft deep 4 ft wide.

2 bags of Fox Farm Ocean Forest and a bag of perlite

Reflector and balast


Nutrients, etc

MH and HPS bulbs


So ya, that's what I have right now. I'll have another update tomorrow with more pics when I actally set everything up.

Hey welcome to growing!!.

What kind of ventilation are you planning on using?? what power is that Ballast?? I use digital balasts currently using x2 600w with silver star air cooled hoods with a 8 inch fan to cool them down which it does with ease!!

Hey! Your questions, haha, make me realize I don't know half the stuff I thought I did. But they do raise a few important points. Mainly, ventilation. Currently, I have none. I know I'm gonna need it with a 400w light and I have a reflector hood with the vents already in it for ducting. I just don't have any ducting or a fan (intake or outtake), so any ideas on that are welcome.

Yay, it's finally all set up!



But boy did I run into a problem when I found out I had metal studs....so I got these hooks that just go into your dry wall and each is supposed to hold 30 lbs so I got two.



But just incase I set up this little emergency system with an aluminum bar and chains.



Next update you'll get to see some tap roots!

Hey, Yeah its alwasy when you think you know everything you realise you know nothing at all.. Iv been growing for about 7 years now and i still know nothing lol.. As far as ventialtion goes its on the most important/exspensive parts of the grow.. Il give you an example. My grow room is 2.6m long by 1.2m wide by 2.4m high. ITs a totaly selaed room no windows just a door walls and a roof. To keep x2 super 600w Super HPS cool I have to use a 1100m3h 8inch fan, I have this set up to suck cold air in from the loft (holes made in ceiling) run through both lights then back up in to the loft through the fan then down into a spare room (3 holes made in ceiling). Temps alone in grow room with that fan on, on a warm day = 80.f Now I have x 1 6inch fan blowing cool air in and a 125mm fan/filter sucking the old smelly air out the temps never go over 75.f now. In total for the fans/acustic ducting/filter and clips etc must of cost around £400 -- $700.00.. Alot i know but they do the job well and i cant smell a thing.. My whole grow so far must of cost around £1200.00 --$2000.00 but damm i got one cool set up

You need to get the hot air from that light out!! you need fresh air in!! you need old smelly air out and filterd and you need a small fan to move air around!!

peace

P.s check out my thread for ideas + your welcome to join in

Ya, I guess I'm gonna have to take a trip back to the grow store and pick up a fan, do you think a 4 inch fan would be enougn for sucking hot air from the light? Also, do you have to cap one of the vents on the reflector hoods or do you leave one end open?

match the fan size to the vent size on the reflector, if its 5 inch get 5 inch if its 6 inch get 6 inch, if you want leave one side open i would attach a carbon filter to the end of the fan/duct run so it pumps clean filtered air out of the room. It would be best through to vent cool air down from the loft into the hood then back up or out of the grow room and have additional ventilation for the gr. Hope this helps

Yes! That helps a lot. So I was wondering, if i hook up the fan and carbon filter blowing out, and I left the other vent open, would it be enough suction to vent the room of heat and odor, keep in mind there will only be 2 plants in there.

It depends on where you are venting the heat out to.. If its back into the same room the closet is in then no. Reason being the room will heat up to the same as what the closet would of eventualy so it really needs to be vented away from the room theat closet it is.. With regards to will it be enough. this depends on 1 thing. how much money do you have for a fan/filter/ducting?? I would say a minimum of a 6'' fan to cool that light and extraction of the room!! What is the avrage temp that room where the closet is?? after all having a 70.f room will mean the air cooling the lights will start at 70.f. Dont forget heat rises so alot of the heat will be at the top of the room..

peace

So I was wondering, since my seeds are almost ready to go into dirt and I don't have a seedling tray or anything like that, what would happen if I just put them into the grow room and set the ballast to put out at 250w instead of the normal 400w, would it still be to much light this early?

Theres no such thing as to much light at any stage any time.. The question is how close can you get the light with out hurting the fragile seeds.. I can have my 600s 12 inches off the tops of the plants ( choose not to have it so low so more plants can be put in for a greater light spread) The 250w will be good depending on how close you can get it. I wouldnt run the 400w lamp in the 250w mode either.. If i was you just for the first 7-10days got some of the home CFL light bulbs get about 4 20w ones (equivlent to 100ws) and put 2 over each plant its the safest/cheapest option you have right now unless you have the $$$$£$$$$ to spend!! peace

Alright here's a quick update.

As you can see on the top we have one girl with about a quarter inch tap root, she's ready for dirt. And on the bottom, we have a fuckin' $10ish dud....I guess these things happen. I may try to break the shell a bit myself and then just put it in dirt. If that doesn't work I may just germ another one real soon.

Some seeds can take upto 14 days to crack.. The water method is just usualy to tell if the seed will or wont germinate.. Usualy if seeds float there the duds and the ones that sunk all ways crack. well thats in my experiance.. You could take the one thats sunk and put it in the wet towl method.. IS the cup of water warmed?? is it out of light?? only asking as warmth brings on germination and soo does complet darkness!!

(remember your trying to imitate the wild)

peace

P.s after re looking over your thread your grow closet will need to have the floor coverd with some type if mater proof membraine.. That flooring will be fucked otherwise by the time your done.. Even if you are using trays for the pots. Get your self to the nearest DIY/Hydro store and grab some waterproof plastic sheeting .. White mylar is usaly the best as it will reflect some of the light back up.. Talking of reflectivity what are your plans??? every lumen counts

Ya, after a bunch of discussing and stuff my girlfriend and I decided to bite the bullet (monetarily speaking) and we're ordering a fan and ducting and mylar and maybe a few other things. Probably from HTG supply, but I'll look around for better deals.

Ooops, already ordered from HTG Supply. Oh well. Here's what we got.
HTG Supply - GrowBright 6" High Velocity Inline Fan
HTG Supply - 50 feet by 50 inch roll of Mylar - 2 mil
HTG Supply - 6" Flexible Ducting - 8 Feet
HTG Supply - GrowBright Indoor - Outdoor Thermometer with Hygrometer
HTG Supply - Nutrient Syringe

That's pretty much it for now. The only other thing I reeeealy want is one of those Co2 boost bucket thingys, but that'll have to wait a while for now.

dude your gonna HATE mylar.

i woulda got poly. its way easier to use, mylar is a BITCH as it cracks leaves fingerprints and is hardly malleable like poly.

but your grow looks good man.

i have the same thing going except in a tent with a 1000watt.

even if the tap roots dont show, plant them.

ive had seeds grow weeks after planting them.

do you have a veg room or setup?

as if you want constant bud like most people your gonna have to do it perpetually.

Hmmmm, well I guess I'll have to just make do with mylar for now, if I do hate it, I'll switch next grow.
I don't have seperate rooms for veg and flower, I just don't have the space. But I was thinking about starting a micro grow veg room, like a pc case or slightly bigger, then I could make it perpetual.
As far as the seeds go, whenever I wake up tomorrow I'm just gonna put them in soil and then put them into the room under a 400w MH, I could run it at 250...idk. So that'll be my next update.

run it at the highest you can.

if there are heat issues then turn it down.

you can build a SUPER simple veg box that can fit up to like 15 solo cups into.

with like 2 sheets of plywood and some 2x4s.

theres a thread somewhere here ill find it.
