150w HPS Club and Resource Guide......
- Thread starter Pipedream
- Start date
Alright, so I just went away for three days, and right before I left I gave them their first real feeding. They exploded! 
These plants are 23 days old, from the time they showed above the soil. How are they looking?
Edit: They're each under 45w of 6500k and 15w of 2700k CFLs. I think I'm going to flip them to 12/12 under the HPS at the end of the month, a little over 5 weeks from seed. They've been LSTed to the ground, and now most of the side growth is uniform. I really wish I had planted them at one end of these tubs when I transplanted, because I don't think I'm going to be able to wind them down to the other end before they get huge.
I'm shooting for 2-3oz, how long should I veg them for for that to be a possibility?

Bounty,
Your plants look great! Your set up looks exactly like mine, same weather station, and pots look the same too.
2-3 ounces you are almost sure to get. You may get more.
The highest yeilds for 60-70 day flower period is above 4 ounces.
I would flower very soon. Do not wiat till the end of the month, that is way too long for veging for a 150. You should flip today, or within the next few days.

Mycall,
I used a Solid State controller to try and muffle the horrible noise coming from the Vortex. However, I sent it back to the hydro shop.
The thing actually created MORE noise. A buzzing sound got louder, as the fan got quieter. The damn controller would vibrate and buzz all night long.
In the end,
the vortex 172 cfm and can9000 was over kill for a stealth 150 bedroom operation.
And yes thats inculding the $100 special fiberglass insulated ducting, Its attic and homemade muffler. I stopped working on the cabinet for a year after this episode.

Apologies for being away so long. Life got me by the balls.
Sugabear, your moving on huh? Your habbit grew beyond the boudries of the 150? hehe. Well man, I hope you can continue to stop by and share your knowledge.
Hope you finnaly get that 1gpw mark. Surely you will under a 400. Perhaps even 1.125gpw like the SSScrog OG guru.
I wana thank you again for the beans. They have been sitting in a dark cool place awating thier new cabinet. I have been contemplating over a new 150hps stealth box that will be pushing the boundries of micro. Your Indica style OB1 should fit the profile for such a grow. And the eligible cabinet canditate? The Mills Pride U2!
But I got two important questions first...
Do you think I can do it with 18" from floor-bulb?
Anyone know if I can remote ballast the Floralux *mini* grow light without fucking up the reflector??

Attack of the webfooted molokai monster! Help! Invasion day 48.
Carbon filter is working perfectly! Cooling the ballast, exhausting scent-free air. Not a hint of green. Infact, my room smells fresher than ever!
Panasonic whisper fan 80cfm 0.3sones, 20 watts. $100.00 ebay.
2.5 pounds of activated carbon pellets. The carbon layer is two inches thick. Five pound bag $30 at exotic fishstore.
CLONES AND VEGGING:
-Eight cuttings were taken.
-All were placed in a perlite wick system clone chamber: Plastic containers, wicks, water, perlite. Simple!
-The clones were left alone for 2 weeks. No attention was given to the cuttings.
-On the 14th day, I noticed white fresh roots above the perlite! I removed each cutting, only to find massive root systems streching 12" long 4" wide!
The roots even tapped through all the perlite, through the wick, into the reservoir! Six had roots, two were alive in stasis. All have yet to revert, and were still continuing to flower!
-Each of six was put into a 4" pot of 40% perlite, 40% wormcastings, 20%black gold organic soil. Soil because I couldent find vermiculite! Placed under two 19watt CFL's, 6500k. Air exchange 20-30x per minute!. Temps 0-1F above ambient.
-10 days after transplant all clones have new growth, yet show signs of yellowing. Some have browing tips/leaves on the newest growth emerging!
They are slowly reverting to veg, yet some still have a few individual calyxes!
I think its cause the soil was too hot; If vermiculite was used instead of soil, perhaps the clones would be healthier. Yet, they are all growing steadily.

Wow I didn't realize I should flower so soon. Looks like I'll have to finally get that cabinet lightproof then. Maybe I'll do that tomorrow morning, I've got all day off. I think I'll be doing 8pm-8am lights on, so I'm thinking 8am Friday will be their first dark period. It'll probably be a few weeks before they show sex right?
I think once I start flowering I'll get a diary going

my update:
Tomorrow will be 5 weeks flowering. 48 day flowering my ass. These are the phenos that are more on the sativa side, so I think these ak's are going to go a full 60-70 days. This pic is actually from almost a week ago, and they've fattened up quite a bit since those. Looking pretty booomb.
The plant in the front has more of a fruity, spicy smell. And looks like she's going to take a little longer than her sister behind her.
The plant in the back smells DANK. She actually wasn't really stinking too much, but all the sudden she's reaking of hints of coffee, skunk, and the classic kind stench. Loving it.

Bounty,
8pm-8am is what I do. The average wait seems to be 10-14 days before signs of sex.
Nuglet,
Thanks for the link & info!
Seems like a good deal. I never seen a 35watt HPS! heh.
Holdin,
Nice plants man. Those pots, are they 1 gallon? They are looking so good in that small pot, I would like to see those girls in a 5 gallon each!
60-70 days for a stativa dosent seem too long. Though 48 days seems unbelieveable.
The mothers of my 3 girls took 87 days, and the big one 133 days!

No, they're in two gallon. The 1gal pot that you see is a lonesome clone that was rejected from the clone chamber due to space issues. That clone is from a really stinky, indica pheno which I had to chop due to height restrictions. It'll be fun to get a taste of what my next run is going to be likeBulénath said:
I really wish I'd at least put them in 3gal before flipping to 12/12. Every other grow I've done I've used 2gal pots and had good results, but this one I WAS going to remind myself to try some bigger pots for sure. Oh well, too late now.
Yup, 60-70 days for sativa is peanuts. 130 days?! I'd go fucking nuts. Really. But these plants are ak48's... which are notorious for shitloads of different phenos. Apparently I got dicked with the slower-finishing sativa pheno's. Going to be some dank though
The indica pheno that I wanted was the plant I mentioned earlier that I chopped. But I've got 4 clones left of that pheno and it should be DANK. Fat little leaves, reeks like coffee mixed with draino mixed with... dank herb. Hopefully that'll be the "48 day strain."
Waiting... waiting... waiting....

Hybridtek,
Everything depends on *your* situation. No two are alike.
The Vortex 172cfm fan may be overkill, but thats my opinion as it pertains to a bedroom operation. The fan can be heard through doors!
Regardless, the thing sucks up roughly 70-80 watts. And it costs $180-$220+ with can 9000 carbon filter. (I paid $280 after shipping)
Most 150watt HPS growers seem to want stealth, minimum electricity use, and over all top-notch efficiency, utilizing to the max every single watt to produce just a lil more weed.
If you were growing in a basement or seculded room, and didnt care about using an extra 50ish watts, then having that much ventilation could only be a good thing!
Unless your ambient temps were too low...
So in the end it depends on your situation.
What could I reccomend?
Im still searching for the holy grail of ventilation, but I fear everyone has thier own holy grail. At the moment im in the design process for a U2 cab as well!
The current plan: To make it the shortest flowering chamber ever: 18 inches floor-glass shield. (maybe someone has shorter for a 150)
This is because the panasonic whisper fan and custom carbon filter is the safest option for my situation. And the catch? Its 12 inches high.
Many would tell you to use a couple PC fans. They are small, efficient, and if you get the right one, they are relatively quiet. They are not powerful like Inline Fans, Squirel Cage Blowers or even moderatly poweful Bathroom fans, Panasonic Whisper Fans. etc...
So when you build a custom carbon scrubber, these fans will loose alot of CFM, roughly half. I doubt they could effectively pull through a carbon layer 2" thick (you dont need 2" however, but I use that much). So you need to compensate by using more fans with any carbon filter of any thickness. This means more noise, wiring, space, etc...
But in the end its probably the safest and easiest option for you. Not just because its your first grow and the U2 is a relatively short cabinet.
The best one I found was from CompUSA for $10usd. Heres a picture with the specifications:
Remeber there are two types of noise.
1) Movement of Air
2) Electrical components like the motor. (the dBA usually rated)
The second type is much more irratating, IMO. The screaming of a Vortex Fan, or whining of a PC fan, is not really "white noise". The sound of air blowing is much more soothing on sleepy ears. The trick is finding a ballance between them.
Any obstruction in the path of air, especially a carbon filter, will reduce CFM and increase both motor & air noise. The only exception is Inline fans when the carbon can filter actually muffles motor noise because the thing is THAT loud. (heh)
If I was to use multiple PC fans w/custom scrubber instead of my Panasonic:
1) My abient humidity is higher than 60% on average. High humidity effects the carbon's ability to remove odor! I *might* have to use more fans to power through more carbon as a security measure.
2) The whinning noise created by multiple fans would disrupt sleep.
3) Ambient temps linger around 75-85f year round. Thicker carbon & higher temps means more CFM is needed to cool my cabinet. This means more noise (See #2).
Thats the ballence im talking about. Its different for everyone.
The panasonic was a godsend. Its baffling to experience.
Imagine a fan that moves so much air with powerful force, yet it makes barely a whisper! When I first turned on my 70 cfm, I thought I wired it backward! But then I felt the air rushing out! It could be felt from 10' away!
Also, the panasonic somehow maintains CFM, unlike any fan I know of.
When the vent or intake is obstucted, it speeds up and pushes harder! Makes a little more "air movement" noise, and thats all.
When I built the carbon scrubber for my new 80cfm, I was rolling the dice. I wasnt sure if the fan could effectively pull through 2" of carbon. The CFM couldent be maintained, and lost some speed, seems like 30-40% tops. The whisper incresed slightly, with a litle choppy sound, but its still extremely quiet. However, the cabinet remains within 4-5F of ambient! So it works perfectly.
(Rough total: $140usd:
Fan, shipping, screen, wood, screws, carbon, cord, special filter sheet material listed on first post)

Here something I just dug up for ya:

So just look up what you want on their web site and give them a call with the product number, when they ask if you have an account just say, "no, I just wanted to come in and pick it up" and they'll ask for a name (fake of course) and if you'll how you'll be paying (cash of course).
For those interested in a quieter inline fantech fan I recommend calling them at 1-866-710-4769 and they will be more than happy to give you the name and number of a local retailer. Again the savings is substantial, a FR150 (250CFM) model will run you over $200 at a hydro store, but my local electrical supply place sells them for $147."

To give you an Idea of how my 80cfm panasonic sounds while powering through 2" thick & 2.5lbs of carbon...
Are you familiar with this HEPA filter? Its a small one about 6" high, 10-12" long... About $20 at WalMart...
Well it sounds quieter thanthis on "low" setting:
Heres a repost of the beauty:

Hi Bulenath,
thank you for such a massive response, great stuff. FYI, I have been growing for 7 years, outdoor, indoor, and now DWC which I have fell in love with. I have to move soon and my situation will be different, I need stealth. The 150w club is truly inspiring....my first cab I built was made from 8 PC fans (4 pulling and 4 pushing) and mounted a height adjusted homemade reflector with (4) 42w cfl's.
Problem is...I need a small more compact efficent cab and the U2 looks perfect for a split cab (DWC on both sides) Im gonna vegg and scrog on the other and flower the scorg on the other so I'll have constant scrog going back and forth.
I plan on having a fish tank with air pumps to drown out noise, Im just wondering if it's sufficient to block out the Inline fan, 4 way air pump, and 4 PC silent case fans.
BTW - great carbon scrubber! I might try it out but I am concerned that the 80 cfm is enough to cool a U2 with a 150w. What do you think?

Hybridtek,
I dont know if the U2 can hold a split operation of flower and veg with the 150HPS.
As the cabinet is, your already pushing 52+ watts per square foot. Its small enough to consider ventilation and heat problems before splitting it between two chambers.
A 100w HPS would be more feasible for a split cab.
No way could any fishtank muffle the vortex. I never heard a fish tank that compares to 4 PC fans, but its possible. The air pump noise, well yeah you can play that off with an aquarium.
When using fan(s) between the bulb and colas, I think the 80cfm panasonic as an exhaust is capable of cooling a U2 with a 150 HPS. Its smaller than my current cabinet, but it should work well reguardless of the tighter space. Besides, the reduced airflow is caused by the carbon layer being 2" thick. This is a precaution I take because of high ambient RH, perhaps uneccessary in dryier climates.
Many growers use a thinner layer of carbon with success.
As stated earlier, my abient temps linger around 4-5F above ambient. I have an Air Condition running during lights on, that keeps my ambient temps between 72-77F and abient humidity around 40-55%.
As far as using 4 PC fans for intake, and 4 for exhaust, your better off using all eight for exhaust. If you want a perpetual harvest, might I suggest buying a the Mills Pride U3, thats only 2' high, 15" x15". Perfect for a veg/clone/mom chamber. Or going with a 100HPS.
However, just cause I cant come up with any Ideas for splitting a U2 and using a 150, dosent mean you cant make it work.

Its smaller than my current cabinet, but it should work well reguardless of the tighter space. Besides, the reduced airflow is caused by the carbon layer being 2" thick. This is a precaution I take because of high ambient RH, perhaps uneccessary in dryier climates.
Many growers use a thinner layer of carbon with success.
As stated earlier, my abient temps linger around 4-5F above ambient. I have an Air Condition running during lights on, that keeps my ambient temps between 72-77F and abient humidity around 40-55%.
As far as using 4 PC fans for intake, and 4 for exhaust, your better off using all eight for exhaust. If you want a perpetual harvest, might I suggest buying a the Mills Pride U3, thats only 2' high, 15" x15". Perfect for a veg/clone/mom chamber. Or going with a 100HPS.
However, just cause I cant come up with any Ideas for splitting a U2 and using a 150, dosent mean you cant make it work.
