My 2nd grow, 400 watt hempy scrog, 3x White Russian

Start here my friend!! https://www.rollitup.org/hydroponics-aeroponics/546006-world-hempy.html

Great group of ppl that are very helpful. I will give you a bit of info that I have for Hempys. You want your ph in around 6, give or take 0.2. Also, have you heard of the lucas formula. You only use Micro and Bloom of the GH Flora series. Grow isn't needed as the Micro has enough Nitrogen. Under T5s, cfls n such the mix is 5 micro/ 10 bloom per gallon, and under Hid lamps use 8 micro/ 16 bloom. As always you need to step up nute strength, so start at 1/4 strength for the young hempys and then step up till you see signs of nute burn (if u see any) back it down a bit. Check out the thread I posted and google Hempy if need be. It is so simple that it may seem almost to easy, but it is exactly that. I have my new clones in hempy cups and will be transplanting them to 2L, at the latest this weekend.

On the topic of Co2, I've read that it is more beneficial on closed environment grows. Although you could possibly use it in your set-up but would have to have extra timers to shut the extraction fan off while your Co2 is being applied. Hope to see ya in WoH, a bunch of pages to go through but it seems to be worth it so far. Peace!!

Thanks for the info man, i have stumbled upon the WOH thread and looked threw it a bit for ideas on how to set up a hempy system it is a wealth of information for sure but it is so huge lol, and as far as lucas formula goes i have heard of it and knew that it only required 2 out of 3 parts of the flora series but i wasn't sure how well it would work since im using flora micro hard water, i figure I've got all 3 in the series so im going to go ahead and try out the regular flora series and then next run try out the lucas formula. As far as the c02 goes if i was to set it up in my room i would run a separate ventilation system for my light that probably goes from the attic back to the attic and then set my filtered ventilation system to only turn on when the room reaches a certain temperature with one of these http://www.amazon.com/Lux-Heating-Cooling-Programmable-Thermostat/dp/B000E7NYY8 , I'm not sure how i would set up the c02 regulator to run though lol wouldn't want to kill my self in my sleep...

Well i finally got my stealth dressers passive ventilation finished up I'm not going to show the front of it for stealth reasons but ill do my best to show the way it is designed, ive also included some pics of the 2 clones since i got them out of the cloner and into the beer cup hempys, i still haven't gotten them fed yet but i will be starting to fertilize with this GH flora series soon since they are showing signs of growth.

Here is a picture of the in side of the veg cab, the entire thing is light proofed i accomplished this using caulk, weather stripping, and expanding foam.


Here is a picture that shows the exhaust port on the rear door, it also shows the weather stripping being used to seal the door.


Here is a picture of the light trap duct flange that seals when it is mated with the back of the dresser, when the dresser is mated with the flange the negative air pressure from my flowering room ventilates and filters my veg cab.


Here is another picture of the exhaust port and the lock installed on the bottom of the door.


And finally here is a picture of the light trap air intake in the bottom of the dresser.


And last but not least here are some pictures of my clones, i believe this first one is the Blue Cheese clone i took,




And here is the White Russian.

So i just finished my temperature test and i must say i am pretty surprised as there doesn't seem to be much of a difference at all between the 3 settings on my fan speed controller, here are the results...

Medium/high, test Furnace 72f 12 hr test min intake 68.5 min ambient 75.0 - max intake 73.4 max ambient 77.1 the difference between ambient and intake min 6.2 max 3.7.

Low/medium, test furnace 72f 12 hr test min intake 66.0 min ambient 74.4 - max intake 74.1 max ambient 78.9 the difference between ambient and intake min 8.4 max 4.8.

Low test, furnace 72-74f 12 hr test min intake 68.7 min ambient 75.00 - max intake 74.1 max ambient 78.9 the difference between ambient and intake min 6.3 max 4.8.

Here are some pictures of my half completed scrog crates i just need to put the side rails on and attach the screen and i will be done with them, then i just need to finish my hempy buckets and light trap and im done.

Well i finished my crates today so now i just gotta light trap this duct and drill the holes in these hempy buckets and I'm done, i still need to fertilize my clones but I'm worried something is going to go wrong and kill them lol, I'm also still not sure whether or not my water has chlorine in it or chloramine ><.

Well i got into my veg cab today and i checked my min max hygrometer and found that my cab had reached 101.5 some time in the past week or so, i noticed that the tips of my plants leaves look a bit burnt too, I'm running a test to make sure that I've got every thing under control, I'm quite surprised i thought my ventilation would be powerful enough to keep every thing cool, but this could also because i pulled the veg cab away from ventilation flange and left it for to long with out active ventilation, either way i am suprised that these 2 27 watt bulbs can generate so much heat.

Good luck with revegging a clone. I'm subbed.

They are already done reveging i believe, 1 of them is already starting to show some fan leaf growth and both have fully developed root systems, thanks for taking an interest.

Well i finished up my 24 hours veg cab temp test and it looks like im in the clear, the min max temps at intake were 69.9-76.2 and the min max at ambiant was 82.7-89.0, i know its not perfect but its good enough for now, im still amazed that 2 CFLs can generate so much heat, i thought the whole reason people used them was because they were to cheap to get ventilation, but it seems to me that with as many of these things as you would need to flower your temps would be fucked...

Imo cfl's are good for under the canopy lighting. T5's or low watt MH's are best for veg. I'd make your exhaust or intake a lil bigger to get those temps down a touch, 89 is getting up in the to high side. Could mount a small muffin fan inside your closet to help a lil more umph on the passive draw. Then you wouldn't need to change any of the ducting or intake. Just a thought!!

Hmm that is an idea, i dont really like the idea of a comp fan though i would rather not have cpus fans spliced into ac adapters because i am paranoid about fire and it would be out side the range of my fire extigisher, i might put a 4" booster fan on the other side of the closets intake flange though, i think the problem is that the under door intake is a lot less restrictive than the multi light traped veg cabs intake so its a lot harder to move the air, i believe a booster fan would solve that problem i just dunno about the noise it would put out.

Any advice guys, https://www.rollitup.org/general-marijuana-growing/611804-how-light-proof-must-i.html

You could add the fan anywhere in the (veg) exhaust system. I just figured having it inside the closet for better draw. The muffin fan I was thinking of plugs in the wall just like your light or other fan (a 4 - 5" muffin fan moves around 30-60 cfm). An inline booster fan would work also, just about anything to help the passive draw along better The best application would be your best guess as I can't see your complete stealth set-up. That being said you are worried about light proof, then an inline booster would be your best bet, as it won't disturb your current set-up on either end.

Ahh i didn't realize that they made muffin fans that plugged directly into the wall, but i must agree that i think the booster fan would be the best option as it wont disturb my current light trap configuration and it would probably move decent CFM with the help of my flowering room exhaust, i just don't know about the noise, i really wish i had another veg lighting option once my cuttings start growing into mothers they are gonna need better lighting than 2 cfl bulbs and my veg cab is already hot enough as it is, i considered t5s but I'm afraid the light rig would be to big to fit in my tiny veg cab, an HID would be to hot, and LED's would be to expensive. For now what I'm going to do is move my rooted cuttings into my flowering room throw them into the 5 gallon hempys and turn on the big light, i still have a while to go before i need my veg cab completely ready, it sucks though i thought i was done. ><

So i finally got my water report in the mail today and i found that it doesn't state whether they use chlorine or chloramine to disinfect the water, upon doing a bit more research online i found a small piece of information that says they use chlorination to disinfect the water and not chloramination so hopefully that's a good sign, i guess we will find out...

Well i finally got my plants into the hempys, i also got them fed and got them under the big light, when i opened up my veg cab today i again found that the temps had reached 100F both plants look like they have been burned a bit but it looks like they will recover, i fed the plants each 1 half gallon of water that was mixed at 1/4 tsp per gallon of gh flora series, I'm hoping that getting them out of the hot veg cab and feeding them will give them a nice boost in growth, i intend on feeding them 1 half gallon 1 time per day until they hit the res.



White Russian


Blue Cheese

Well it looks like i have officially fucked up on my hempy grow for the first time, that didn't take to long, i opened up my grow room to find my blue cheese pretty burnt up, I'm not sure if it is nutrient burn or light burn, so i would appreciate any info you guys could offer there are more pics in my thread. The temps were in check and the light was about 3 feet from the plants so im thinking its probably nutrient burn. unfortunately i retard-idly used the recommended dosage for cuttings against myself and shaggons better judgment lol. The blue cheese was a very fussy plant threw out its entire life so i am thinking i possibly just confirmed which was which by accident.

Well in the process of trying to save my reveging clones, i believe i may have put the final nail in there coffin, while i was trying to transplant the clones back into there smaller solo cup hempys i managed to destroy the root system of both plants, i made a 45 degree cut to each of the stems dipped them into rooting hormone and put them back in the bubble cloner. I doubt they will survive so i am going to be starting up 2 new seeds soon, one of them is going to be world of seeds big bud x northern lights from the medical selection and I'm still not sure on the other one.

So its been 7 days since the incident and surprisingly both of the clones seem to be doing alright all things considered, the Blue Cheese has regrown its roots but the White Russian has not, I'm pretty surprised because the Blue Cheese looks a lot more beat up than the White Russian clone, i also just got my rockwool today so i will be germing 2 more seeds soon...
