yep, been scopin' out Afro-pips strains for a while. There's an indoor "mini" version of Malawi Gold that only gets 3' tall if you grow it 12/12 from seed.
C99, Grapefruit, and Arjan's Haze #3 all stay relatively short also.
No shortage of good genetics these days, just not enough time to grow all these great strains.
Yeah, I read their description, but I was curious about his seed source, Nirvana, or a distributor. Durban Poison and some sort of hash plant, no doubt.
Africa is a very, very large place and SA is vast. Many, many strains on the continent, Sun you might like, and could probably grow with your settup, Malawi Gold.

My tents are 32" x 32", but the inside measurement between the frame is 30 X 30", so I searched for 30 X 30 trays and came up with these:
Plastic cage pans - Rabbit Cages, Rabbit Hutches
They come in different sizes. The 30 x 30 fits perfectly inside the frame members of my tents.
Yep, if you need to hang that much weight, the GrowLab is a better choice.
The bigger the space you want to filter, the bigger the filter needs to be, and you want to match the cfm rating of the filter to the fan. If you get too powerful a fan, the filter won't work well because the stinky air gets pulled through there too fast to remove odors. It's OK to have a filter with a higher cfm rating than your fan, but not the other way around.
If the carbon filter and fan are part of your ventilation system for your plants, you calculate how many cubic feet of space your grow room is, and then choose a fan and filter that will exchange all the air at least 2 times per minute.
For instance, my tents are roughly 50 cubic feet, so I would use a fan with at least 100 cfm rating to exchange the air twice per minute. The filter does create drag and reduces the efficiency , so it's better to go higher and get a 150 or 200 cfm fan, and then a filter that matches cfm rating.
If you're not using the fan and filter as part of the ventilation system, then you would just go big enough to do the job on controlling odor.
How long the filter lasts depends on how much stinky air it has to filter and how much flow there is through it, so they can last a long time in some grow rooms, and not as long in others. Average is probably around two years or so for most growers.
The pre-filter that goes around the carbon can is important because it filters out dust that would quickly clog the pores of the outside layer of carbon, so the pre-filter helps extend the life. It's usually recommended to wash the pre-filter about every six months or so to maintain a good flow rate.
A lot of carbon filters now come riveted together so you can't service them yourself and change out the carbon, but you can drill the rivets out and replace them with screws, then buy some activated carbon and refill it.

bad ass my friend! thanks for the link, i knew you had some good deal on those things like you always do, i am kicking myself in the ass for not asking you 1st. those are nice trays to. they will work good if i fire up another tent.
thanks for the info on the filters.

Re: 420 Cannasumer Reports Competition - GrowLEDHydro 300w LED vs. 400w HID
oh man, we're in trouble, cause I got no sense of direction whatsoever, lol.
"shall *we* guide thee" is right
.
the latter
I watered my buckets today and noticed that my plants looked yellow and hungry before I watered them, and then began to green up nicely right afterwards.
So, I'm thinking that the conventional wet/dry cycle might not be the best for these CRF's. When the medium dries out, the plants don't get fed well, so might be better to not wait until the containers get too dry before watering.
I'm familiar with the Claber Oasis watering system, and it does look like a good option for being away from home for a few days. It's battery-powered, so no worries about power outages, and it only holds 6 gallons, but that's enough to keep a few plants going for a few days.
I hadn't seen those fertilizer delivery stakes. Great idea about using something like that loaded with CRF prills.
I'd be a little concerned about roots growing into the holes and then being ripped out if the stake was removed, but there's ways to avoid that.
Thank you for the NPK info and the significance of having enough P. I had a feeling I was looking at things too simplistically, but I'd hope the researchers at Scott's, Florikan, etc., would have those ratios and delivery generally worked out, so that the commercial crop growers (and us) don't have to supplement or fuss too much.
I hope that's the case, because I would like to use grow methods where I can just add water throughout the grow.
yep, there's huge benefits. I couldn't believe how much cooler things ran without a big hood trapping heat and blocking ventilation, and how much more distance the plants needed from the bare bulb to not get burned.
Eye safety is a concern, but there's ways to stay safe walking the vertical edge.
thank you TL!

Re: 420 Cannasumer Reports Competition - GrowLEDHydro 300w LED vs. 400w HID
I haven't compared directly, but it wouldn't surprise me at all if a bare bulb runs close to or cooler than an air-cooled hood, assuming you had a fan blowing straight up at it from below and decent ventilation.
The bulb is right in the airstream, and with no hood blocking airflow, it's a very efficient setup.

Re: 420 Cannasumer Reports Competition - GrowLEDHydro 300w LED vs. 400w HID
if so then why would anyone run a air cooled reflector? why not just a bare bulb or batwing? ive always thought vert setups ran hotter then air cooled hoods.
you have me interested now.

Thank you SS for your acknowlegement. It is a privilege and an honor to watch you and the members of 420 spread the knowledge. The things I have learned here in the last 2 months is incredible.. its better than taking a college course and spending a crap load of money. I have been officially deemed disabled by the government thats the good news, but in the last 2 years I have become a "pharmaceutical junkie" due to chronic pain. My state has not legalized medical marajuana and I am active in that pursuit. The bill has been passed by the House of Representatives, but due to the lame duck session due to the elections it will not be voted on until spring. And when it passes, I will be the first in line. So I consider the things I am learning here a future endeavor. So keep the knowlege coming while I sit in the back row and dream. You guys rock!!!
PS I am surprised PETA has not shut us down for killing mites!! LOL

hey man hope all the votes go through over there it will become a new and closer step on our fight to legalize it!!!! lets spread the knowledge!!!!
You came to the right place and i agree with you i feel like im at school here and like a teacher all at the same time it a lovely place!!!!
:focus::focus::focus:So what's good with the updates i wanna see how the competition is doing!!!!!!!!!!!!!!!!!!:focus::focus:

Re: 420 Cannasumer Reports Competition - GrowLEDHydro 300w LED vs. 400w HID
I apologize for not updating and for unanswered PM's.
Life's a bit crazier than usual right now, but everything's cool.
I'll do a pic update asap.
The plants are doing OK, except that I'm still fighting a mag deficiency, especially in the HID tent.
Some of the newer leaves started to show it also, so I foliar sprayed a few times with 1tsp/quart of epsom salt, and that helped some, but it seemed like a band-aid fix.
I watered today with RO and 1 Tbsp/gal epsom salt, PH'ed to 5.9, so we'll see what effect that has.
The LED side isn't nearly as affected by the mag def as the HID side.
I haven't LST'ed them yet, because I would like to see the mag issue improve or resolve first.
will get some pics up asap so you'se can see what I'm talkin' bout

You beat me to it:
I was gonna ask the same thing.
Isn't magnesium better absorbed above 6.0?
FWIW, I'm using a coco based soil in the top half of my pots and I've had just a touch of a deficiency too. I don't know enough about coco to make any suggestions, but mine cleared up with weekly applications of my micro-mix, which is mostly epsom salt.

Re: 420 Cannasumer Reports Competition - GrowLEDHydro 300w LED vs. 400w HID
I'm not sure what's causing the mag def, because I prepped the coco with 5ml/gal Cal-Mag, and I used RO water with Cal-Mag to water.
It seems like a mag lockout issue due to the coco holding on to too much calcium, but the only calcium they got was from the Cal-Mag prep and the Cal-Mag I supplemented the RO with to water. They've only been watered twice since the transplant into the hempy buckets, the last being last night when I switched from the Cal-Mag to epsom salt because I didn't want to give them more calcium.
I guess the DM could play into this if it takes a while for it to build up an adequate level of mag in the medium, or if the coco is sucking too much calcium out of it until the coco's CEC stabilizes.
I've PH'ed my water to 5.8-6.0, so I don't think it's a PH issue, but I haven't checked a sample of the coco. You can't just check runoff like with soil because runoff in coco doesn't reflect the PH in the container.
We'll have to see if things are looking better after the watering last night with the epsom salt instead of the Cal-Mag.

Re: 420 Cannasumer Reports Competition - GrowLEDHydro 300w LED vs. 400w HID
Did you flush the coco 1st before using it? also do you feed it cal/mag before putting the girls in it? IMO with TRF its best to water a few times before transplanting the girls, to let things balance out. but i know allot of people use cal/mag before adding their plants. but it could be salts in the coco if you didnt flush it. i know all different brands will do different things, and ive never seen hydro farm coco being used.
i am worried about the same thing if i use coco, i am thinking of going back to SS#4 mix its always did pretty good for me, and i think TRF would like it.

Re: 420 Cannasumer Reports Competition - GrowLEDHydro 300w LED vs. 400w HID
Nope, didn't flush or rinse it, because Hydrofarm's instructions are to just hydrate and use it
I'm thinking I should have rinsed it anyway, but I figured a company as prominent as Hydrofarm wouldn't be selling salty coco.
I agree that it would be a good idea when using CRF's to water the container a couple of times before planting, especially in soilless mediums, so that there's nutes available when the plants go in.
I used RO with 5ml/gal of Cal-Mag to prep the coco, but that didn't prevent the mag deficiency I'm having.
Coco has a learning curve, and I'm willing to invest the time and energy to learn to use it, but this isn't a good grow for that.

High NCDude!
You could try using other nutes, but you would still have the CRF nutes in the medium, so whatever else you added would be on top of what's already in there.

ya i here you, company's will say that for sales, i much rather buy some coco that i can just use out of the bag, you feel me? so they say stuff like that some times.. ive seen allot of cheap hydrofarm products, its kinda like the Sunny Select, or any retail store knock off brand they sale cheaper then the big name products IMO.lol
Canna and Royal Gold are the only coco's to go with IMO.
I was told by a coco grower friends that been using it for about 6-7 years to pre charge the coco with 10ml cal/mag per gal before anything is planted, then add 5ml once a week from their on. keep PH around 6.0-6.3 IMO..
i have many friends that only grow in coco and do great with no problems. it could also be that the TRF just arnt any good for coco and u need a coco nute? they just might be too slow at feeding the cal/mag for coco or just to low of cal/mag and the coco sucks it all up.
coco is not easy to learn, thats why i haven't used it yet, too scared. if things seem not to work to good for you in coco with the TRF i will try the SS#4 mix and see what happens? that way we can see how different mediums work with the TRF.
