WhyNotA2 Started three seeds in rockwool. Soaked rockwool in 5.5 solution before dropping the seeds in. Placed humidity dome over the rockwool. The first 5 days in the humidity dome, I used 7.0 water and misted the rockwool as soon as rockwool started feeling dry. Day 6 moved under lights and used 1/8 strength nutrients. Photo is of day 7. Planning on moving to DWC bucket tomorrow
I used rainwater with ppm of 15-18 and mixed 8 gallons with 18 ml of GHE Bloom, Gro and Micro with 4 ml of CalMag. Both buckets have new PPM of 350-390. Is that too aggressive for day 9? Or can I push more? New to DWC and growing and hoping for some applied knowledge. Thanks
WhyNotA2 I used the GHE nutrient calculator and batched it for half strength for seedlings. I made 8 gallons and I have been trying to keep substrate temp to 68 Fahrenheit using ice bottles in the buckets. I have an 8 inch air stone and a 3 inch air Stone in each bucket running off an EcoAir 4 air pump. I have a air purifier right next to air inlet for the tent and a small fan clipped to tent. I also have an inline fan with a carbon filter. I'm not currently a green thumb and not sure what I am doing so I am trying to create a narrative for future grows. Any tips or suggestions is much appreciated!
For plant 1 of my DWC, I had 410 PPM two days ago. My resevoir now is at 440. She is slightly yellow and a tad droopy. Is the rising of PPM by 30 an indication of nutrient lock? If its nute lock, does this require peroxide water to flush? How long do people flush? Thx in advance
Hello. you have a very young plant there. They should be a bit bigger before full hydro treatment. Give more plain water then nuts at this point. I water twice then feed then more water. I think you are trying to make it do more than it can. Funny, in about 6 weeks you won't be able to slow it down. Good Luck. Chuck.
My plants are on Day 14 and have started to have some leaves twist and taco a little. I lowered the water level thinking that it was probably because the rockwool was too damp. Does this train of thought sound right? Am I overanalyzing and these look fine or something else? Thx
60% RH is pretty high when you grow in water. Better seeing as you have water under your plant to try to get you RH down around 40% and see if the leaves straighten out. Like using a bubble cloner, you dont need a dome over your girls. Cheers friend
WhyNotA2 I just started LST with a few ties to the side of the buckets. Plant 1 bucket I plan on doing without any temperature control of the reservoir. Plant 2 I plan on keeping temperatures right around 68. Curious to see the difference with that being the only difference. I will try and keep everything the same for both plants and experiment. Trying to figure out how important a chiller is for DWC. Might look into trying to insulate the 5 gallon bucket for better temp control. Sprayed neem oil / coco wet onto plants this week. Plants have puffy leaves with pronounced wrinkles. Dark green in color. Probably nitrogen toxicity. Will take last two days of nutrients out and flush with hydrogen peroxide/ water mix. Also lowered the PPM before flushing by taking out 30 oz of nutrient water from the reservoir and replacing with 30 oz of cold pH 5.8 water. Topped both plants on day 19 from seed.
In DWC growing, chillers are really expensive and frozen water bottles you need to replenish kind of frequently. Does anyone currently use any insulation for their 5 gallon buckets? Do you have a rough estimate of how many degrees it cooled your bucket? Doing a temp study. Thanks
Can you use a foliar spray made from organics (fulvic and humid acid, potash, sea kelp, wetting agent) in a DWC? Or is using any organic material more trouble than it's worth? Is week 3 too early for foliar spraying? Hoping to green my thumb a bit. Thanks
The upper part has no relation with the technique below, as far as I researched. So if you wish, and if your climate conditions inside the tent allow it without problems, you may do so! Care with the dosage, it seems to have a great amount of Hum. Acid. on it!
WhyNotA2 Plant 1 is going to get a bump in its feeding schedule this week while Plant 2 is going to half strength. Only difference in the two buckets has been Plant 1 has no temperature controls on the bucket. I raised PPM in Plant 1 to 475 this week. Plant 2 is now at 200 PPM and recovering from root rot. Thank you to all the folks who answer the questions in the forum. I don't personally know anyone that's growing so huge help.
Running an experiment on temperature control on DWC buckets. I am seeing that no temp control in DWC thru 3 weeks has been beneficial. Same strain, environment, training, topping and all. Curious what's going on. Maybe hotter temps for first 3 weeks helps due to evaporation?
@MrBlocc420 The uncontrolled bucket temperatures have ranged from 74-79 depending on time of day so far. It's getting colder here quickly. I imagine that the 79 will be the high temp for the remainder of the grow. Controlled bucket has been between 63-69 the entire time with vast majority of time being between 66-68.
@The8thChevron I should probably clarify a bit. My tent temperatures are the same for both. Only difference in the 2 plants so far has been temperature of the water in my DWC buckets. One I keep at 66-68 and the other is whatever the tent is. Root system is maybe 3x the size.
I donβt know where your temp in buckets are but optimal temps in my room in my medium is anywhere from 65-74 degrees on hot days or heat waves Iβll drop temps to 65 to keep plants comfortable. Up to 80 degrees is fine. Any higher your plants will stop taking up nutrients . I will love to see how high your temps get and how your plants react I am curious

WhyNotA2 Things are going well this week. I topped Plant 1 two more times (both sides). I took off two largest fan leaves that were under main branches. I have supercropped two branches in an effort to beef up the top portion of Plant 1. Plant 2, I have softened up the stem by squeezing the plant in an effort to strengthen it. PPM for Plant 1 was at 450 beginning of week and Plant 2 was at 200. Plant 2 is recovering from root rot and is just now starting to grow again. Changed nutrient schedule mid week. 2.5 gallons for Plant 1 and used 11mL Gro, 6 mL bloom, 9 mL Micro, 5 mL diamond nectar, 4 mL rapid start, 4 mL Cal - Mag and 1mL Floralicious Plus. Plants immediately responded positively to the reservoir changes. Plant 1 grew about an inch overnight. PPM for Plant 1 is at 500 PPM. Thoughts or suggestions are appreciated to improve my grow.
In a mostly indica strain, for a 2x4 tent and a 240W LED. Does it pay off to top 2x? I have 5 nodes of new growth after topping and not sure what my next steps should be. I am training the entire thing but feeling like I should do something additional. Thx for any suggestions
WhyNotA2 Week started off with 600 PPM (early weeks 3:1 Gro to Bloom; this week is transition to 1:1) nutrient water in Plant 1. Started adding 1 liter nutrient mixtures of 800 PPM. PPM keeps dropping, will continually up nutrients until it levels off. PPM seems to have leveled off around 700 PPM. Plant 2, upped nutrients to 500 PPM. Looks good right now. Mid week plant had abrupt change in pH for at most 12 hours. Adjusted pH and later adjusted nutrients. Plants are starting to touch so planning on flipping to flower next Tuesday. Hoping to strengthen interior branches before flipping. I upped the dimmer to 90% of the lights capabilities. Temperature of water has become an issue the last two days. I have been topping off reservoir 2x a day with refrigerated nutrient water. Putting in 2 or 3 liters for Plant 2 a day and 1.5 or 2 liters for 1. Please jump in and share thoughts if I am doing something that doesn't make sense. Thanks to the community for helping me get here and Hey, hey, hey smoke weed every day

WhyNotA2 Changed nutrients to flowering. Light dimmer is at 90%, will raise it to 100% by end of week. Rinsed the roots off before changing nutrients. Deep cleaned the new bucket, the old airstones and tubing. Dehumidifier is keeping room right humidity wise. Temperature is a challenge right now but have 2 fans. Will continue topping off with refrigerated nutrient water throughout the week. Put in Scrog net midweek. I have slight nutrient burn right now so keeping the PPM tame to start. Took off sucker parts on lower portion of Plant 1 and a few interior fan leaves that were just driving up humidity early in week. Did same with plant 2 later in week. PPM is up and down this week for both plants. Found out that I am just slightly overfeeding so I'm finishing the week off with 400-450 PPM top off. After chatting with a few folks, I was convinced to defoliate. I followed a passed down rule of no two fan leaves can touch, no leaves that completely overlap, no leaves that don't receive light and lastly none bigger than my hand.

WhyNotA2 Both plants are chugging water. I went through roughly 10 gallons last week between the two ladies. PPM is starting to be stable around 450. By end of week 600 PPM was good. Ph has been good for awhile but had a day on Plant 1 where it dropped overnight to 4.8. Light dimmer is at 100%. No burn on plants at 12 inches, got as close as 6 inches. Didn't see light burn but didn't feel comfortable that close so took it down to 8 inches. Temperature has been good but had times where it's getting up to 30 C. I have left her alone for the most part after the defoliation. Only thing I have done is bend a few shoots under the trellis net and softened the branches to beef them up a bit. I removed a dozen or so fan leaves throughout the week that were covering grow sites. I plan to defoliate on day 20 or 21 of flower and let it go from there. Any suggestions on what I should do differently or a way I could enhance my grow..... i would really appreciate. Happy growing

WhyNotA2 Went out and purchased some diluted monosilicic acid. From what I understand it's the best way to have your plant digest silica. I have been squeezing and softening the branches for last 10 days and will continue throughout flowering as long as branches aren't brittle. Defoliated / lollipoped on Day 20 of Flowering. My PPM for both plants went up from 650 to 725 at end of week. Only increasing the Bloom nutrient with a touch Floralicious plus and Kool Bloom throughout the week. Had some clawing on lower growth early in week. I had a bit of light burn at 6 inches and decided to move plants to 9 inches from light. Love to hear any feedback or suggestions to improve. Thanks to the community for helping me get here.

WhyNotA2 Week started off really great. Ppms are at 750-800 and showing no signs of stress. Light is at 9 inches. Mid week PPM spiked to 1000 and lessened feed to get to 850-900. Week started off with 5.6 ml/Gal for Bloom and plan to have it at 6.4 by end of week. Increasing Floralicious Plus and KoolBloom by 0.1 ml/Gal too. I will cut back fan leaves as they cover budding sites and will start breaking the interior of the branches again once they fully recover from the defoliation. Not much to do this week with the recovery period included. Buds are noticeably getting thicker. As always, if you have any comments or suggestions on how I can improve. I would love to hear them. I am a beginner who has only book knowledge so practical application gardening techniques are needed. Happy growing

WhyNotA2 Really strong lately. Both plants filling in, having a pH range from 5.9 to 6.2, PPM from 900-1000, humidity is 45 +/- 3. Drinking heavily. I gradually upped my Bloom from 6.4 ml/gal to 7.6 over the course of the week. I gradually lowered my Gro from 1.2 to 0 over the week. I added a touch more Cal-Mag and Kool Bloom. I gradually lowered the Diamond nectar from 3 ml/gal to 1 over the week. As always, I am actively looking at ways to improve my grow and techniques. Any suggestions are appreciated. I have book knowledge but not much applied. I'm looking at adding a UV-B light for the next grow for flowering for a few hours a day to see any benefits. Trimmed a few leaves back from covering budding sites.

WhyNotA2 Week is starting off well and things have been running smoothly for two weeks consecutive. PPMs are between 900-1000. Trying to keep pH at this time from 6 to 6.3 to help digest extra PK. I plan to drop PPM to 800-900 over the course of the week to get ready for flushing. Buds are noticeably adding weight and getting more trichomes built up. Hoping for another 2 strong weeks and hoping to harvest around Oct 17-22. As always, I love input and hearing about other folks success stories so feedback is great. Appreciate the community for the help so far

WhyNotA2 Smooth sailing for awhile now. I changed up my strategy a little and decided to keep the feed in the 900-1000 range for a bit longer. I changed the PPM on day 4 of the week to 850 by removing 1 liter of nutrient water from the reservoir and replaced that with RO water. I have removed many of the nutrients I was using previously. By end of week the PPMs were at 750. Now the feed is just micro, bloom, Flo + and Cal Mag. I have been consistently opening the door to the outside before the ladies bedtime to help induce some purpling. I am not positive if the lowering of the air temp and lowering of the water temp right before bed induced the purple or not but they're now purple. I'm noticing some slight cal-mag deficiencies so I put a wee bit more in.

WhyNotA2 Week is starting off well. I have had a few of the larger colas start to fall over. I have added a few velcro straps to help keep them up. I removed 16 oz of nutrient water and added RO water from each bucket to lower PPMs 800 to 750. I plan on topping off reservoir with RO until I see some amber trichomes. At that point, I will swap out buckets and start the 5 day RO flush. I swapped to plain RO water on day 4. I am going to flush with the lights on for days 5 and 6. Night 6 I will start 72 hours of darkness. Any suggestions or tips are always appreciated. Old knowledge but no practical application of the knowledge so still figuring it out.

WhyNotA2 RO water only, chop down on day 57 from start of flower after 72 hours of dark. Will dry for 5-10 days at 50% humidity and a light breeze under the upside down hanging buds in darkness at grow room temp which is 70 F. Plan on curing for at minimum two weeks and will take an oz out and keep curing the rest until and repeat this process until I'm out of herb. I plan on using the waste material by making some dry ice hash. I will put in the harvest information after I do my dry trim so maybe 10 days from now or so. Thanks to the community for helping me get here. First grow has gone really well. I have learned rain water in DWC works just as well as RO. A chiller for DWC isn't required and may only be a tiny help. To keep a plants form in flower, I should be using a tomato cage or some bamboo stakes to keep them up..... silica alone isn't enough. You don't need to have any root zone protection to have a successful grow in DWC, just good genetics and good hygiene practices (washing hands with plant based soap). You don't need flavor enhancers or sweeteners to get top shelf weed. I also learned that I can grow marijuana successfully from seed to chop down!
@MrBlocc420, appreciate it. I still don't really feel like I know what I am doing. Just enjoying this grow and hoping in the future I get good at it. Love watching the progress
@WhyNotA2,yea me too love to watch them grow . You are definitely doing a good job she looks way bigger than mine in your hydro system. Keep it up ππΎ
Hey bro looking good. Are you running your ph at 6.1, that is in the flower stage for ph. You wanna try and keep your babies at 5.8 for proper nitrogen uptake in veg state. Cheers friend
@MrBlocc420, Thanks man, what I lack in experience I hope to make up for in being a helicopter parent. I had a few hiccups in overfeeding but smooth outside of a few days. She got sugary really quickly and starting to really be stinky. I have been watching your grow and she looks perfectly symmetrical. I'm pumped to see how yours turn out.
@Canna96, Appreciate it! From looking at your journal and other folks'.... it looks like I have a slow starter. Hoping to get her to your heights by the end. Excited to follow your grows
I have done this experiment myself personally.. And I had the same results... The Water chiller did ZERO difference.. In fact I saw better grown in the Reservoir without the Water Chiller then with it... Was a what the fuck moment for me... I have spent about 400 dollars on water chilling up to this point... And now the two water chilling units I have.. Are sitting on the shelf collecting dust. Maybe yours too?
@DeadwebsiteBoringcommunity, This is my first grow that I put effort into. Reading online what it takes to grow a plant. Makes me think I need a PHD in botany before I can start or 5000$ dollars to pay for everything to be automated. I can never figure out what are the real requirements for a healthy plant.
@Canna96, Appreciate the encouragement! I plan on being active and uploading photos as I go. I have been quietly stalking other folks grow journals for some time now and finally got the confidence to start
Looks great bro. I don't know about Co2 indoors without having a sealed setup, but it's already starting to get cool enough that I have my windows open to get some fresh air in. I'm in Mass. When it get's cooler I try to run an intake that brings fresh air into my room... outside air has something like 3-400 ppms of Co2.
You are doing well mate. It happens to everyone that you know sometimes the nature of the seeds or whatever. Cannabis can explode in veg stage as well day by day not only when flowering starts... Your plants are dope and you will get nice results I am sure. @WhyNotA2
Keep up your hard work man :)
how do the roots look on plant 2? my plants look like that if I have some root issues. I had some algae early veg from light leaks for the longest time.
@WhyNotA2, depends what you want to do. Root rot doesn't mean your plant will die. I would pop another seed or two, but try and save this 1 if you have the time and space. It is a great learning experience. Sometimes it is hard to get rid of, but you can definitely save the plant. Also, you got root rot because your environment wasn't right. You had high water temps, light leaks, or something to cause the rot, so it will happen again unless you figure out the cause of the root rot. My guess is a light leak in the reservoir.
@@motaman311, for this bucket I believe it has to have been light leaks. Is it possible that I brought in the bacteria for root rot from the ice bottles I was using to cool the water? Also, if I wanted to try and save this one..... where would you start? The internet is misleading when you search for troubleshooting like this
@WhyNotA2, it took me almost a year to figure out my root issues. I had some successful grows because some plants can battle through better than others, but I almost switched to coco because it was so frustrating.
It is possible the water bottle could bring bacteria in, but I doubt it. I would be more worried with the frozen water bottle causing root damage if it touches the roots. I was never able to save any plant with h2o2, but many people use it very successfully. There are only so many things that can cause root root, so eliminate them and you are golden. For example, I was using hydroguard, great white, I brewed a compost tea for bennies.. all these things help combat root rot, but I still had issues because I still had a light leak, so no matter how much stuff I put in the res, I couldn't get rid of the root rot.
Make sure all your stuff is clean, take the plant out and rinse the roots off with water. Maybe top feed of some water/h2o2 mix through the hydroton. Wash and clean everything.. air stones, air lines too.
Here is a good forum post with a lot of info.. other people commenting on how they fixed their issues too: https://www.rollitup.org/t/guide-to-getting-rid-of-root-rot.347697/
you r overfeeding
ur ph is too high
u wanna cover everything................u dont have to ................but it gives u better results.....................even am air line exposed to light f.... things up in my opinnion
@grzesiekkuzniak, crazy how much junk there is on the internet. I have read a few times pH should be 5.9 or 6.1 and some say anything from 5.5-6.5. I used 1/4 the amount of nutrients the labels recommended for seedlings so strange it's too high
@Inganjawetrust, much appreciated! It's been awesome and I plan to get up and going again in another month. Do you have any recommendations of favorite strains to grow?
@Ferenc, Thanks man! I'm hooked! It's been a great advantage to be able to look at journals like yours and emulate PPM values or pH at different stages or a training tactic etc.
