Life just got better!

So today I checked the garage temp in the middle of the hottest time of day and it was around 31C outside the tent and 28C inside the tent. By this time the lights had been off for about an hour. I also installed a 4" inlet fan today to see if that helps. Lights are switching on again soon so i'll keep a close eye on it overnight and see what temp does now, still just gonna run the bigger light for now to see.

Oh, sorry, outside the tent around 27-30C depending on the weather, luckily rain cooled it a bit today. I've switched off the smaller led now so that less heat gets generated, the spread from the bigger led should still provide enough light over all 3 plants. I'll keep it like that for a few days and see if they start recovering Haven't thought of boxing them off yet no, not sure how I'd go about that?

Hey man, Yeah the one LED is a pretty big unit and gets pretty hot. Ambient temp is usually around 31C, Ambient temp at "night" which is from 11:30 to 17:30 sits between 24-28C the last few days as its been pretty hot outside. The tent sits in a garage with no windows or ventilation and that could be a huge factor also. I have also experienced the humidity going up a lot during lights off which is why i decided to run the extractor all the time during that period, at least when the lights come on the heat reduces the humidity, which gave me the idea of trying the 15mins on/15mins off cycle. But yeah like i said due to the heat I should probably consider just running it 24/7 and add the other fan when January decides to end one day :'(

Im thinking my next investment should be in another fan asap that can suck through an air filter and blow new air in? And then I can run the extractor on its same settings mentioned above. Maybe for now its best to just leave the extractor on 24/7? The temp is still running a bit hot around 34C at peak. Humidity around 30% now before I water them again later today.

OK so I made some other changes in the setup also. I moved the carbon filter to the top of the tent and also opened one of the flaps for outside air to come in. I've put the extractor on a timer so that it switches on every 15 minutes and then off for 15 minutes for the light on cycle. And on all the time for the light off cycle.I figured that way the plants get some time to take in some co2 when the lights are on? You guys reckon they will recover?

Im running 18/6 in full spectrum currently. Switches on at 17:30 till 11:30 the next morning, so yeah mostly runs over night. Ok I see, thanks for the advice again, so would you recommend i leave the extractor on 24/7 rather? and should I look into adding an inline fan as well?

Ok cool will do.. Thanks for the advice, What you are saying makes sense.. I do water less regularly now, but temperature Im still struggling with managing. At peak it sometimes hits 36-38C. I have the extractor on more regularly now with the help of a timer, I would leave it on 24/7 but then humidity sometimes drops to 20-30% and Im scared thats a bit low? Im contemplating adding a fan that blows air in from outside, as right now I only have the desk fan inside and the extractor with a air filter for letting new air in, but maybe thats not enough?

kiwiseeds.com is also pretty reliable, they are a sister company to Barneys Farm and use the same shipping methods/rates.

Sorry for only posting pics now, they come out weird under the lighting, hopefully guys will still be able to see something. The dry leaves are a lot lighter in colour than in the pictures, some slight yellowing happening on the tips of the bigger new leaves also.

Yo man! Sorry for the delayed response.. Grow is going a bit scary, beginning of Week 4 now, but at the beginning of week 3 quite a few leaves started dying. It couldve been many factors, they seem to be recovering now and new leaves are still coming out. At first i thought I couldve been overwatering, so i let the medium dry out a bit and gave it a good water again with 1/4 grow nutes. and now I wait longer periods before watering. Was doing light watering every 2nd day with a spray bottle, now i do about every 3rd but without the spray bottle and I give it enough so it runs through a little bit now. It couldve also been the lights hanging too close, but they were a good 60cm in veg light cycle. I raised them by another 10cm about. I have also switched to the full flower spectrum now on a 12/12 cycle, still havent added the co2 mix as Im scared it might explode with my luck. The last thing it couldve been was accidentally getting some drops on the leaves while watering them with the spray. I dunno, maybe someone can identify the problem better here, I'll try adding some pics of them tonight but Im almost too embarrassed to show them :'( With them being Autos im scared I mightve stunted their growth a bit now, but lets see. Either way im learning and its still fun

Yeah fo sho, keeping it on the slightly moist side but not drowning anything. 2 are looking healthy but one seems to be a bit slow and struggling compared to the others. Not sure if it was just a dodgy seed or if I stuffed something up, but i'll give it some time and see if it catches up, I'll try add some pics tonight to show what I mean.

Awesome, thanks for the explanation. Makes sense. Gonna try my best to manage it as accurately as possible. After this long weekend i was able to check in on it more regularly, temperature fluctuates between 27 and 32 depending on time of day and whether lights are on or off. Humidity is between 50% (with extractor) and 80% (without extractor). Havent added co2 yet and not really sure how i'll measure it just yet if i do.. All 3 seeds popped out by day 3, today is end of day 4 and start of day 5, still just giving them plain water till they have a few more leaves then i'll start feeding them in small amounts.

Greetings Grim, Stcik with me here, I know I am new to the forums, however not new to growing. 1. Use rockwool cubes to germinate in, squeeze the excess water out and leave them on a warm sunny windowsill or dstv decoder until they sprout. You can plant straight into coco/perlite, be very careful not to over water. The seeds stay to wet and rot. Same applies to papertowel, don't keep it too wet, and don't let it dry! Rockwool has a brilliant air/water ratio for sprouting seeds and I typically achieve 100% success with expensive seeds. I find rockwool to be the superior medium for germination and cloning. 2. I cannot emphasize enough he importance of pH and EC. Invest in good quality meters or suffer the endless headaches of thumb sucking it. Bottled water cannot be trusted for pH as it can differ vastly from what the label states. 3. In such a small grow do not bother about about CO2. Especially since the tents are not likely in an air sealed room. 4. Again ignore CO2 unless you are growing in an air sealed room. Hope that helps! Hey Swazigh! Thanks for your feedback, all solid advice. I'll definitely get some rockwool cubes and Hopefully my PH tester arrives soon as well. The tents are kind of in a air sealed room, my garage doesnt have any windows or nothing so it does tend to get a bit stuffy in there which is the main reason why i was considering it.. Maybe i'll just add a smaller 2L mix and see what happens? or what would you suggest? Thanks again! Appreciate all advice!

Howzit man, thanks for looking and the good questions. Yeah, i'll still sleep on the co2 mix for now and see how it goes. I did a brief test last night with the lights and desk fan running in the tent, and the filter off. I was getting around 30 degrees with 70% humidity, so it's slightly on the high side and the lights werent on full spectrum yet so it might get a little hotter when flowering starts. Im thinking of maybe adding another fan in the top of the tent and maybe keeping the air vent flaps of the tent open on the side? Extractor is a 4" fan, connected via ducting to a 4" Carbon Scrubber. Incoming air is running through a air filter (regular type like cars/bikes use) connected via ducting and housed outside of the tent. For the second tent im also still in the market for some lights, right now not much is happening in the second tent, but the plan is to have a veg and grow tent set up eventually. I put the seeds in to soak in Ph 6 water yesterday at 16:00, so i'll plant them today at 16:00 straight into the medium. Will feed it only pure water for 7-10 days and then introduce some biobizz grow as feeding probably once a week while vegging.

Hi everyone, So I'm prepping to start my first grow and would like to share my setup so that I can get more solid advice from the vets here My setup consists of: 2x 120x70cm GT hydro tents 1x Mars Pro II 160 LED (https://www.mars-hydro.com/mars-pro-ii-epistar-160-usa.html) 1x Mars Reflector 48 (https://www.mars-hydro.com/mars-reflector-48-usa.html) 3x 3 Gallon Smartpots 30cm Desk Fan Hygrometer 1x Extractor Fan/Scrubber for humidity control and for when the smell kicks in during flowering Nutrients: I have BioBizz Grow and Bloom Medium: Coco Peat/Perlite mix Seeds: Sweet Tooth Autos I have installed everything so far except for the Reflector 48 (need some hangers), and I still need to set up a yeast/sugar water co2 mix. Im also aware that I'll need a Ph tester fairly urgently, but i ordered online and now have to wait patiently for delivery. I have mixed the peat and perlite and flushed it with water, then added some cal mag and wet it again, and then let it dry and potted he mix in the 3gal pots. I need some advice on the following, 1.What would you guys recommend as a germination process? Should i soak and paper towel them, or soak and plant directly? Or just plant directly? or Rockwool? 2. Seeing as i dont have the Ph tester yet, what water would you guys suggest for germination/seedling stage? 3. Regarding co2, Will a 5L mix of yeast/sugar/water last long enough to only change it out monthly? or how should I calculate and monitor it? 4. Also a co2 question, I have read it should only be fed co2 during "day" time and must be removed at "night", will it cause problems if the co2 was left in 24/7? Im sure im gonna have many more questions as time goes by, thanks for reading this far, I'll appreciate any advice.

Hi there @420SA! Thanks for the warm welcome and advice. That's good to know, so you would recommend I start with some fems first rather? I do have some that i ordered earlier this year that can work, only reason I was thinking auto was for the quick turnaround time just to have something ready in 3 vs 6 months. But i hear what you saying, that theres not much room for error with autos and I didnt think of that. I think i'll follow your advice and go with the fems.. I have some other noob type questions but i'll make a new thread for that in the appropriate section where i'll explain the setup in more detail. Thanks again!

It's the 120cm X 70cm from gthydro, couldn't find them new but got lucky on gumtree

Hello everyone, and thanks admin for letting me in Im a new grower but old lover of weasel. Been sampling and tasting for over 10 years now, very excited to start my own grow. Will be asking plenty questions here when i come across any challenges. Gonna be doing a 2x4 tent grow with LED lighting. Thinking of starting with some auto flowers for now while getting familiar with the process. Looking forward to learning lots from everyone here.
