Blue Mystic - CFL Closet Grow Cabinet

[foulplayer]

I've been actively perusing the forum for about two years now, learning as much as I can. I made a grow cabinet about 8 months ago and finally got around to start my first grow. Currently in my cab i have six 6500k 26 watt and four 2700k 26watt cfls. One 120mm exhaust pc fan and two 80mm intake pc fans. I lined the cab with an emergency blanket, which turned out like crap.

I have about 22" height of growing space from the top of soil to the highest point that I can raise the lights too. The cabinet is 37" tall, 34" wide and 18" deep.


Not to worried about the light leakage because the closet doors stay closed.

Future mods: Replace blanket with mylar, add a second 120mm exhasut fan, make a carbon filter. I might attempt making light traps for the fans, haven't decided yet.

Blue Mystic femenized seeds from Nirvana. Really pleased with their service, speed, and stealth. They shipped on a friday and it was in my mailbox the following monday. Really fast, I was expecting weeks but it only took 4 days.


Germinated two seeds in paper towel, 24hrs later one sprouted and the other looked like it was about to pop. That night I planted them both using Fox Farms Ocean Forest soil. Two days later they sprouted.

I'm thinking I might start on 12/12 this weekend considering my height limitations and me being a rookie, not really knowing what to expect growth wise.

Whats your thoughts, should I go 12/12 this weekend, let them go all natural or should I consider lst, scrog, topping?

hey man, nice set up. with your space limitations, to increase yield you might wanna try a scrog. look up a way that you like best and go for it. as far as the light schedule, id wait another week before flipping to 12/12.

where'd you get that light fixture? i use cfls for my seedlings but my set-up is ghetto. i like yours alot

Thanks, the light fixture came from Home Depot and was less than $20.

 

[mystifiedbongs]

i use ffof too bt i was told by a few trusted people on here that you need extra drainage at the bottom of the bucket. i used 2-3 inches of hydroton but u can use broken pottery, rocks, even marbles im told. im also gonna mix in 25% perlite into this next batch.

Over the weekend I added a second exhaust fan, 4 cfls and thermometer. Now I have a total of 14 26watt cfls. I had to turn off 4 of them due to the temp in the cab getting up to 97 degrees. Running 10 lights for now and the temp this morning was 90, with 30% humidity.

On staurday I noticed some spots on two leaves of one plant and three leaves with yellow tips on the other plant. Not for sure what could be the cause, I ph the water and havent used any nutes yet. Just plain ol' fox farm ocean forest soil.

Yellow tips. Right plant.


Spots. Left plant.

nice setup bro get some more exhaust way to hot in there should never let it get above 84 stresses them out. i see you mix match you cfls thats what i do as well that way you get the red & blue spectrums. check out my video and questions ask everyones always willing to lend a hand.

I grew out Blue Mystic a few times last year. Definitely, not what you see in the picture...

It is a medium/short sized indica dominant plant. It won't stretch much on you when flowering starts. You don't need to worry about this strain "getting away" from you but you may still want to use a Grow Through Plant Support to independently train each seed. Did not respond well to topping but did well with LST.

In Flowering it is a VERY, very very very, sensitive plant. Anything will stress her right the eff out. Heat at 90 is a HUGE issue when you're 15 degrees over the ideal temperature. Get down under 80 and they will thank you for it. Try pushing a little more air into the cabinet as the only way to accomplish this is through air movement.

Before you start flowering I suggest rinsing (not flushing) the soil to ensure you don't have any buildup. Generally, these plants will burn around the end of the stretch period, so just watch out for it.

The smoke off of these plants is very "Blue" tasting so avoid burning them in the first 3 weeks of flowering and they will EXPLODE during weeks 4 to 6 to give you a great finished product at the 60 day mark. What you are seeing right now with the tips burning up is a heat response. Get those temps down, don't burn her, and she'll really pay off in the end. It's a 7/10 strain, when grown proper, IMO. I'll never grow her again though.

Thanks jhod, I've been following your thread, like your setup. Especially like the video updates.

Wow, thanks for the info. I just ordered two Grow Through Support hoops from amazon. I didnt realize the heat in my cab was so high until last night when I installed the thermometer. I will add a desk fan inside, maybe that will help with the temps.

I'm thinking I might replace my 120mm exhaust and 80mm intake DC computer fans for two of these 4" 120VAC fans, one intake and exhaust. http://www.radioshack.com/product/index.jsp?productId=2102825

You could do way better for about the same cost as all these funky little micro fans you're running.

http://www.plantlightinghydroponics.com/ecoplus-180-cfm-industrial-grade-blower-p-1556.html

For about $80 you can just solve all the problems rather than buying/shipping more $25 fans.

hmmm... never thought about that. I wonder how much noise this thing makes? The price for the one on the website is $83 shipped, at my local hydro store its $95. I just ordered it from the website. I appreciate your help! +REP for you, jhod and mystified!

He is completely right. Now having 2 120mm fans and 1 140mm fans (total of $50) It would have been alot better to just spend the $80 or $100 to get a good inline fan with a decent amount of CFMs produced. Other then your heat issue good job man! I'm sub'd up so if you need any help I will do the best I can or recommend someone that has more knowledge on whatever situation you seem to come across. Once the heat issue is addressed I'm sure you will do fine. Check out my grow since we are super similar if you have any questions. I ran into some problems and my thread is full of answers. Good luck and I'll stay tuned.

I've seen them as low as $75 at my local hydro store after a discount but that's not going to be the case everywhere you go. I think you made the right decision.

The fan does make a pretty gentle hum. The motor for the fan generates its own heat as well so it is better to place these kinds of fans on the outside of the grow cabinet. Ducting can make placing these fans in the right spot very easy.

The inline variety of exhaust fans, at the same price, are better for residing inside of the grow space because the motor is contained within but they consume a good deal of room and are better suited to larger grow areas that have plenty of free space. In my experience inline fans make a little more noise than blowers. Each has their own advantages and disadvantages but given your space restrictions the blower is definitely the right choice here.

Most of the noise from your fan will come from the woosh of the air as it is exhausted. You might need an attachment to do this but if you run just a few inches of ducting on the exhaust side of the fan this will cut the db you can hear in half. I have one of these fans and a 4" axial fan and the axial fan probably makes twice the "bzzzzz" sound but less of a "wwooosssh" noise. Actually, the noise from my 16" circulation fan overwhelms the noise from the blower.

You are right. The inline fans tend to make a little louder noise. You are correct though with the size. They do tend to be a little large. But all in all a good investment for exhaust/intake purposes. If you are going for more of a stealthy grow inline isn't for you.

Damn I thought these weren't going to start their lovely aroma until flowering. I came home today to check on my babies and my spare bedroom already has a hint of skunk. The right plant from my pictures smells more than the left (I really need to come up with names for my babes. Any suggestions?).

In the mean time to keep temps down until my 180cfm industrial grade blower comes in, I am only running 6 cfls. Temp is now 86 degrees and 37% humidity.

Must be a super dank pheno to have already started smelling. That is an acceptable temperature but should still try and get that down. Maybe add a cup of ice or two into the cab to see if that helps. As far as names go...I would go with something exotic. Like Lucrecia...lol

I wasn't planning on doing an update today but its been pretty slow here at work. Its not much, just a couple of pics. I have succeeded in getting temp down to 81 degrees. Hopefully the blower comes in this week and I can run all 14 cfls instead of 6.

Looking good man. Does it not drop in temp when those lights are off?

 

[foulplayer]

Its amazing how fast they grew in 6 days. Pictures from this morning.

I added the 180cfm blower and got the gro-thru support hoops. I still need to add a desk fan inside because with 8 lights on the temp stays at 86 degrees. With all 14 lights it got up to 96 degrees. I need to cut the legs down on the support hoops before I add them. I decided to switch to 12/12 this morning.

 

[Bird Gymnastics]

Looking good man. Nice and green. Can't wait to see those babies start to flower. Now with that 180cfm blower are you still getting high temps?? If so I'd think about upgrading to a bigger box.

Hello, another picture update. Plants look to be doing good, with the exception of one or two leaves on each plant with yellowing spots. I figure its due to the heat in the cab. Running 8 cfls keeps the temps in the mid-upper 80s. With the lights off its gets down to the low 70s. They are stinking up the spare bedroom pretty good, so this weekend I plan on making a carbon filter to attach to the blower. I got the gro-thru support hoops, but I dont think I will use them this time around, maybe next time once I figure out my temperature problem.
