Hey guys,

i started building my first grow cab and was wondering if i could get some opinions on it.. i posted some pics (not much too look at YET) and the plan for it. I ordered a lumatek digital ballast along with 400w hps light with a 6inch diameter cool tube should be getting it this week sometime and then ill be able to cut my holes, mylar that bad boy up and let the magic begin.. let me know what you think!

ill keep postin pics as i begin! thanks

Neato cab.

I want one of those....

Hey looks like a solid set up. Mine is very similar. I was just noticing in the diagram you drew you are going to need an exhaust fan for the cool tube not sure if you knew that or not. My setup was Exhaust fan > duct > air cooled vent (cool tube). And on the other end of the cool tube I just put a filter to keep junk from going into the tube. As long as you have a decent inline fan it will work fine in your space. It will keep the cab well ventilated plus keep it cool. Thats just how I have mine setup hopefully it helps.

edit: and fyi 4 ft vertical space isnt much from my experience. Be careful not to veg em out too tall. Scrog will work too.

Looks good man, couple questions:

1) Will you be adding an inline axial fan to the cooltube? (The drawing only shows the CT and some PVC)
- if not, might want to do that
2) If you add one, or plan on adding one, run it for 24 hours before cutting the exhaust hole for the fan. (That way you can get a thermometer and have an idea of what the temps will be in the box.

After the test, if your temps are higher than 80F I would recommend putting that exhaust fan you have in the drawing, more towards the top and 'behind' the CT. As we know, hot air rises and would be most effective there.

Good Luck mate! Keep us posted!!!

Looking good can't wait to see updates as it goes!

kinda forgot about this thread, started posting on other threads bout my mini yellow spots and lighter little spots (look like scratches) on the leaves... might be the ph being a little too low after feeding it yesterday... might be nothing? still havent figured it out but was thinking of getting some ph up for the next feed.. let me know what u think plz!

Oh and im using a tall pc tower for veg box atm here are the specs
AK-47 clone
75w hps bulb with a home made cool tube (on 24hrs)
temps steady between 72-79 with avergae 35% humidity
flora premium plus soil
Ionic 3 part nutrients (grow bloom boost)
ph between 6.0 and 7.0 ( went down between 5.0 and 6.0 last feeding didnt really see anything bad happen, cept the leaves lookin like they been scratched )

the clone is about 4 weeks old, still no smell that normal ?

hey wanted some feedback asap so gonna bump this!

hmmm i dunno... it maybe the pH. it's quite normal that there's no smell.

you should maybe flush your soil with ph water.

Also it seems a bit too early to feed this plant in soil... plus the soil looks kinda heavy, does it drain alright?

you may have overfed, flushing should help, but we need to know more about your soil. is it like standard potting soil? or compost rich or what?

all purpose soil..

floral premium plus - contains humus, peat moss, perlite and lime

drains good i believe

is it possible that the plant is too crammed? leaftips are about an inch from the mylar

no that's not a problem...
well i don't know what to tell ya man, the situation is definitely not severe but they are not looking very good. I am having this problem (not looking good but not gonna die soon and still growing) in my garden as well. I'm a perfectionist I like plants to be all green and healthy looking. If they're not it tells me that there's a problem, that even if it will not kill my plant it may still hurt my yield... so yeah you should try fixing it. I'm not sure it's overfed either if you haven't given much nutes just a bit. Flushing is always good I think.

also you are showing many many pics and i dunno really which ones to look at they all seem different
some are showing a color problem - too bright or changing... some are showing weird spots on the leaves and some a minor twisting of the leaves. and the ones in the pc cab are showing a very small and not very healthy looking plant.
so which one?
