looks like the funs about to begin then, have you checked the temp of the cupboard where the tent is, the other thing is the tent is not very high so the hot air cant raise to the top of the tent as much due to it not having much height, is the outlet fan blowing air out the top of the tent and ac pushing air in through the bottom, thats about the best you can do really, but with the high temps you get over their its always going to be tough to control temps in a grow tent, i got similar problem here now we are coming into summer,
so by the sounds of it you got the ac forcing air into the tent or do you have a fan pulling the cool air into the tent from the ac duct, if not try giving that a try, the other fan is blowing the hot air out of the tent into the attic, i think thats what your saying, if not just correct me,
i struggle with temps here in the summer so will have to leave grow door open a few inches to vent the hot air out and let cool air in, i have similar problems but no ac so just have a fan outside the grow room blowing cool air into the room, im sure you know this all ready but try not to have the fan blowing directly on the plants as it dries them out and makes them lose moisture to quick, just added this for any new growers as i made the same mistake, i had fans blowing on new plants and it caused me many problems, i switchd the fans off and had them blowing above the plants then all my problems where solved,
cant wait to see these plants take off, always interested in autos, most end up small but my kc45 is well over 2ft now and just started an purple cheese auto so ill see how that turns out,
Dp,
You have it right. I may have to pull cool air in with a fan. Maybe 150 cfm. The cool air comes in the bottom and hot air out of the top. When I checked my temps before lights on it was 66 degrees!! So now I better just leave it open before I go to bed.. The system would get a bit more hands on if I had regulars. Glad the autos can handel light leaking in! Both girls are rolling now. The upside down tap root of my blue critical finally grabbed hold and the seed casing popped up today!!
id say autos do best on 20-4, they dont need to be 12-12, they can even do 24-0 from start to finish but i find giving them some dark period does them good,
ive even started autos under 20-4 then gone 12-12 when i flipped the other plants to flower, so id have to say 18-6 or 20-4 is the best method for these plants, not sure what lighting your using or if you have both mh and hps bulbs but a lot of growers who grow autos tend to use the mh until the plant has started flowering then flip to the hps,
i start mine under cfl until about 2 weeks old to prevent any stress or light burn or what ever its called, then they go under the dual spec hps on what ever lighting schedule im using.
the way i look at is that an auto is rud cross with indica so its been crossed with a plant that flowers under 12-12, we know rud dont flower according to the seasons so i like to try and keep the lights on longer than 12-12 to prevent early flowering, i may be wrong but i think if its crossed with a plant that flowers under 12-12 then it still might contain some of that gene in it so having it under 12-12 early on might make it flower early,
another thing i am thinking is if their under 12-12 then they may grow a lot slower due to less light hours, so could take longer to grow plus may enter flower early than it would if grown under 12-12, i have not tested a side by side grow to say for sure but at some point ill run tests with a 12-12 from seed and 20-4 from seed and see what results i get, i would try it with the kc45 auto im growing but all the seeds have grown totally different plants so would not be a fair test, if i could find a stable auto strain then i could run tests but for now i prefer 20-4 until they at least get a couple of weeks into flower,
when i have grown this kc45 under 12-12 from seed i ended up with a 1ft plant with tiny buds, this one i got in flower now was under 24-0 for a couple of weeks then under 20-4 under the dual spec hps for another 2 weeks then when i flipped the light 12-12 it had started flowering and the plant is 3ft tall, so from my own experience id have to say that autos benefit from more light, but if your grow room is 12-12 then you have to go with that,
the good thing with autos is you can fit them in with what ever schedule your using, i dont think id want to let light in for a few minutes during dark period as this may stress it, but having the door open will mean as the room gets light then it will get that light so its not like you have a light turning on for say an hour during the dark period then off again till lights come back on, it may stress it the same as it would a regular plant under 12-12.
so if you got nothing else in the tent then id try and give it as much light as possible during the first few weeks or at least till you can clearly see its a week or 2 into flower,
Yeah, Well I noticed when I had high temps and low RH that the soil dried out nearly over the 18/6 schedule, so yeah thats why I just gave 5 Litres in morn and other 5L later, I thought it would retain more moisture as itll be in lights out not long after the rest of the feed.
My soil was rather aerated and didnt hold much as it had less HUMUS in it, but now I have a full bag again ready to roll
Take care my friend, and Im sure youll be fine - even if you have to open the door a crack for couple hrs a day to vent abit but you should be k long as thres enuf air movement.. Cya mate, Chat soon - Smokemup
Nice set up. I don't have any autos going at the moment, but I do have three more of those WW auto seeds that I will be planting soon. I want to see how they do outside during the hottest months of July and August. I really wanted to do them in DWC, but not sure if I want to run 5 of those. I already have two criticals in dwc right now.
But, I think I have that shit down because ph stays stable for days.
dwc with outside sun = hells yeah. I'm just waiting for July to put the two dwc criticals outside.
All my other clones are outside now enjoying the sun. Nights are still a tad cold, though.
IDK about the fans, I have em blazin on all my plants....always have, that's the way the big boyz trained me.....just me, if you have any Rh probs they can be alleviated during dark times with fans. I had 71% Rh night before last, put a 24" fan 3 feet away from girls on high....51% now. I don't notice any detrimental effects.....one 6" fan is 6 inches from a bud and runs on medium 24/7. At my location I have to accommodate periods of high humidity, I have found that as long as all six fans are blowing on the plants I'll never get PM or budrot.........IMHO.
its only when the plants are very young you dont want fans blowing directly on them, it apparently removes to much moisture out the young leaves and causes problems, it stunted my first grows by loads so i have fans blowing above plants for the first week or 2 then have it blowing across the plants after then as the plants are then able to support themselves and the moving air strengthens the stems and branches.
as for autos my purple cheese auto is in flower, its tiny, 3 nodes high, bottom 2 branches are 3cm long, next node up is 4cm long then top node is the bud, so wont be getting much of this auto, the only auto thats produced huge buds is the kc brains kc45 auto regular, the buds on that are over a foot long and i got 4 of them on my kc45, this purple cheese is tiny, ill be lucky to get 3.5g off it when dry, it either needs to have a major growth spurt or it wont be giving much in return for the nutes and time spent on growing,
ive got a few kc45 seeds left so might grow out a male to use for pollen with some other auto strains, hopefully that will give me some regular auto seeds, just hope it improves yield on these low yielding autos,
hey all..thanks for the new subs and great advice! Dp, good advice on my hours..I may go 18/6 and reposition the fans for now. I"m really starting to look at cool tubes..I'm using a 600 watt set up. I did switch to my mh last night. Didn't post an update though. work has been insane lately...16 hour days! Mc, thanks man I appreciate the informative posts..keep em coming! I like your fan set up.
cool no worries,
i have had some strains that suffer with to much light early on, im not talking light hours for strength of light, so keep an eye on them and make sure their not getting bleached or what ever they call it by having to much light,
its the same as taking an indoor plant outside in summer, it can cause problems, most strains are ok with any light but i had the odd strain that i needed to move to a slight shady area for the first week then it was ok after that,
Oh man now I'm worried! Well I hope I'll be OK! The MH bulb is the bluest light I have ever seen. My first time using one. My HPS setup started in the middle of a flower period so this is a first for me..If you remeber I was a CFL nut. Still am but I do enjoy having one light. So far the seedlings look good. The Blue Mystic is finally coming along so I'm feeling good....Can't wait to see if she will give me some purple hues as stated by Nirvana seeds.
i also started with cfls, the 2700k cfls are the orange light, these are the basic household cfls, but you can get the 6400k cfls which are the bluer light suited more for veg, when i was using cfls i used a mixture of the 2,
i still use cfls now for starting seeds and clones under, then they go under the dual spectrum hps for a couple of weeks of veg then change it to flower schedule,
as long as you keep the light a good distance away for the first few days then you will be ok, then slowly lower the light till your at comfortable distance, its a pain to keep adjusting the light but the hps and mh give off lots of heat but using cool tube helps get the light closer for flower,
you should be ok, you got a good idea of what your doing, cfls work well at keeping the nodes very close, its the only reason i still start my plants under cfls.
ive also tried growing purple strains, many say they turn purple under normal growing conditions but i have yet to grow a purple strain that does this, most require a few nights of cold temps to bring out the purple colour, even then i only managed to get purple out of one strain the rest stayed a normal bud color so gave up on the purple challenge for now,
so ill follow along and see how you get on, fingers crossed you get the result your looking for, but i may of harvested to eary to bring out the purple color as i have read it only tends to show up late in flower, i harvest according to the trichs so maybe i could of let it go longer and got the color i was after,
i have seen some amazing looking purples and blues like ken estes gdp, but i have seen ken estes gdp with no purple in it at all, so its a bit hit and miss,
their must be some reason why 1 person can grown ken estes gdp and get purple buds but then another grower just gets regular looking buds, same goes with several other blue/purple strains i have seen many pics of purple buds but then other growers who have grown the same strain dont have the purple colours so clearly their is something that brings out the purple, it could be the temps or even could be lack of nutes, id have to look into it more to find out for sure, but most strains will turn purple when they get cold shock before harvest, it was winter where i was and i put my plant out in the cold during the night and i did get purple buds, tasted and smoked like crap but i did have true purple buds.
ill order some purps the weekend and get some planted and we can then compare grows and i can run some tests and see what works and what dont, i always wanted a nice purple strain, i tried ken estes gdp seeds 5 times now and every seed turned out male, i got one growing now thats male that ill get pollen from and put on my purple cheese auto thats just started flower,
Dp,
Thanks for the feedback....I have been so damn busy with work lately. I have had a difficult time finding the energy to get online! I'm off this weekend so recoup time and read through all the posts I have missed. That said I have a chance to either hit the 18th annual South Florida Tattoo convention or Mud fest in Port Saint Lucie, Florida. Hmmm. Not sure. I'm also currently out of weed! The last of my Mazar just went up. Damn..I like to stop from time to time so this may be a good time!
The girls seem to be doing well. I will transplant them to 5 gallon pots tomorrow. I kinda want to put them in bigger pots since I have the room but I hate to have so much wet soil for seedlings.
