First week in DWC. My tent’s temperature reaches up to 82 F. Even though I’ve had good progress with Hydroguard by itself among other plants but this time I wanted I test the peltier cooler that I’ve purchased and try to control the temperature better and hope for a better yield. Thanks for watching.
I’m sorry you guys, was on vacation for about a week. I did my first res change with ppm at 990 this time. I believe she can handle it. Also the plant looks a bit deformed... I didn’t spect that. Also the peltier cooler works too well and now temp going down as low as 59. May have to adjust that soon but I don’t see any issues at this time as I am doing a coco side by side compare with the same strain.
Okay so I defoliated the plant a little bit. Res temp stays around 64F, which is good but I think I have either algae problem or root rot. I don’t th think its root rot because it doesn’t stink and it washes off easily. I don’t think I have any light leaks. She’s not growing as fast as the one that is growing in coco but I will try my best to keep her going.
Alright, she’s doing quite well so far. She picked up on growing fast again. LST’ing now for even canopies. I’ve been defoliating slowly to prevent overstress and has been working well. She is starting to stink; I think I will put her into flowering within a week. I’ve added terpinator as well
LST going very well with her. I put her into flowering this week along with the coco grows. The roots on this baby is definitely much thicker than her coco counterparts. Res temp stays between 65-70F ever since I’ve cut the peltier cooler power from 24hr ON to 12/12 ON/OFF.
Wow! She just bloomed massively. She is absolutely beautiful. No signs of distress. Did a res change a several days ago. Res temp fluctuates between 65-71F.
Dudes, this girl is butt wild, she won’t stop growing. I had to defoliate her severally times over the course of 2 weeks. I am running out of growing space for her. She measures more than 2x2 (L x W). Drinks more than a gallon of water every 3-4 days. May need to invest in a RO system. However, I am very thankful that shes doing well. This is a GG#4 x Zkittlez by Cream of the crop seeds.
Dialing back down on the nutrients a little bit. She continues to focus on budding but i feellike she’s still stretching. She drinks about a gallon of water every 2 days now. I cannot wait for her to be done.
Do you guys usually bring the ppm down towards the end? I have issues with nute burn and something that represents cal mag def looking, every time I get to the mid-to-end flowering.
By the look of your pictures, you already have Nitrogen toxicity (dark green leaves), you should cut back on the grow nutrients. Your cal mag dose is good enough and even a little on the high side, so I think what you experience is not exactly calcium or magnesium deficiency but lockout. Calcium and magnesium are locked out when there's an excess of phosphorous and / or potassium. The burnt tips on leaves support the theory that you are over feeding your plant.
She’s doing good so far, nothing much to report. She’s getting very very frosty and very bushy. I should have lollipopped her too in the beginning but I don’t have much experience with lollipop. However, rest of the grows will be lollipopped in the future.
A little bit of trouble this week... I’m having heat issues... I live close to the equator, so it should always hot as shit over here. In addition to tham, my plant’s color is getting lighter and slowly falling off easily, Am I having nute def or ph lockout? I changed the res today and filled it with an nute.
Chopping it down today. I apologize for last week as I was on a vacation... I flushed her for 2 days with florakleen. She is going down exactly at week 9.
She was one of the most stickiest cannabis plant I’ve ever grown, especially in DWC. She didn’t need much care and I didn’t do much of cleaning either. The temperature fluctuated greatly and she didn’t care much. She rewarded me with about 3 oz of bud and about half oz popcorn bud that I am going to use for edibles. Thank you every one for taking interest in this grow.
This peltier cooler works wonders... I am able to reach down to 62F (5Gal bucket) within the roots while the tent temperature is 81F. I am highly impressed. I have another cooler that I will add to my other bucket.
@MaryJaneUSA I have done some research on this myself as I have a hydro basin. Lots of theories out there. I try to stick with the scientific ones. The final consensus is 62-72 degrees, with the sweet spot of 66-72. I saw a lot of warnings about anything below 62. Your low of 59 could describe the slow plant growth. Maybe put the chiller on a timer like on for one hour, off for 30 min, then back on again? Good luck!
@BeefWellingtons, thanks man, I know I got lazy with pictures... also I did a res change yesterday, rinsed the roots but did not do H2O2 solution as this is a temporary solution... I did add extra dose of Hydroguard, added b52 and piranha, just gonna see how it works out on a few days. I didn’t adjust my res temp but it fluctuates between 63-67F, I have 2, 4 inch airstones but I’m thinking about adding 2 more in there since I have an extra 254 gal pump
@MaryJaneUSA, well, then here are some ideas. First, please use a flash when taking pics so we can see what you see.led pics don't show anything helpful, except for size and shape. High Times recommends 75f (yes, 75f water basin), but that seems to be in professional, and optimal conditions. I have seen people lift the top of bucket, and dip the roots into hydrogen peroxide bath for 30 seconds, as well as add some to the basin. While this will kill off the pythium, it will also kill off beneficial stuff as well. Anyway, clean out the basin (use a light bleach spray, then rinse), add new bennies and ro or filtered water, ph it perfect 5.8 or so. Make sure you have the full recommended hydroguard in there, and move the avg temp up to 69. I have seen browning roots come back and go white again with hydroguard use at higher temps than what you have. Last, but not least, are you sure your air stone is pumping out strong? You could try getting a stronger air pump and put two airstones in there?pythium thrives in low oxygen water, and can't survive in high oxygenated water (this might be the trick). Please don't forget some root pictures with flash. Good luck!
Love your set up! Hydroponic, LED, main-ling. I'm doing all those things now too. I'll be following with interest. She looks happy. Good luck with your grow! I'm going to look into a cooler after seeing yours.
Also, if you think you might have an issue with root rot, I 100% recommend Hydroguard by Botanicare. It's cheap and works! I have grown hydroponically from seed to harvest for a couple years now and never had an issue. I'm still on my first quart of the stuff too. Good luck!
@MaryJaneUSA, Thanks very much for the input. I'm a stingy bastard :-) so I appreciate hearing about the cheaper way to get it done. I'll look into it and thanks again!
@NorCalCloset, also you can make a dyi peltier cooler on eBay for like $10 a pop but then you’d need a pc cooling fan and a power converter, I bought mine from coolworks so it was more expensive. But sometimes you can catch a really good deal; bought a used peltier cooler with temp controller for $75 on eBay. New ones will cost you 130+70=$200 in which this case, you should just invest in a water cooler lol. But if you get a water cooler, you need water pump and etc. the peltier cooler actually has a probe that touches the water in your bucket and cools it.
These look like they are going to make many many flowers !! :D :D I'm going to follow this one till the end so I can see the lady's all grown up ! Keep up the kick ass work ! Happy growing !
I have been looking for a bucket like this. 5 gallon, 6 inch net basket, 2 airstones, aquarium water chiller, insulated, and finally a top-drip water feeder (that I can put on a timer for 2 15min intervals in 24hour period). Thing is, no one makes these. What size hole/drill bit did you use for the chiller? Do you have top-down water feeding?
Thanks again, great job there!
@BeefWellingtons, thank you so much for the compliment.. I used a 1 1/4 inch drill. I am using coolworks peltier cooler. And no i am not doing a top feeding just regular DWC. I am using refletix insulator and works wonders
@BeefWellingtons, hey so I realized I have my peltier cooler on 24/7 right now because of summer. So I haven’t had the time to try to actually shut the cooler off and see with insulation but with the insulation alone I’m guessing 5-10 degrees F in differences because with the cooler I am able to go down to 61-62 F when the ambient temp goes up to 83F
@BeefWellingtons, Honestly, that is a very good question because I have the peltier cooler on only during the day (18/6 light cycle) when the indoor temp is very high, which is around low 80s. So I will check it out and let you know.
