Weedo's Winter Grow

What's Up RIU?



First, a heartfelt thanks to all of you out there who participate in the discussion. I've learned a lot from all of you. Perhaps, someone out there can learn something from me.



Well, here I go again. I've started another grow. It's a DWC setup with 4 buckets. I'm growing 2 plants of Barney's Farm Sweet Tooth, 1 plant of Dina Fem's White Widow and 1 plant
of G-13 Labs Sour Jack. All from feminized seeds. I use a 4x4x7 tent with a 4" Hydrofarm inline exhaust fan coupled to a 6x24 Phresh Air carbon
air filter. For lights, I use a 250w CFL for veg and a 400w HPS lamp for flower. I'll be upgrading here shortly to a 400w MH bulb for veg. I run Botanicare nutes as a rule but,
apparently, they've stopped making their Pro Grow line so, I'm switching to Fox Farm Grow Big and Big Bloom. I should run out of what I have on hand of the Botanicare nutes sometime
during veg. I hope the plants roll with the changes.


This is my 3rd solo grow. Street prices and street quality here in Vegas became just too unpredictable for my taste. Plus, I'm way too old and (ha hem) respectable to be out hunting
for new weed connections. I enjoyed spectacular success with my first grow. Over 7oz off two plants using DWC in a 2x2x5 tent. I actually still have a little of that weed left. My second
attempt ended badly. It was last summer and temps were way too high. I struggled with the high temps for 6 weeks or so. I could never get a handle on it given my amperage limitations.
Finally, when the house AC system went belly up in July, they were done. Now that it's Winter, temps are mild and manageable. I figure that I have until mid-May to get a grow off
before the heat is, once again, out of control.


I started this grow on January 11th by soaking the seeds in tap water. After a 24 hour soak, I used the paper towel method to let the seeds germinate. Meanwhile, I presoaked my rockwool
cubes in tap water. Once the seeds popped, I carefully placed them in the rockwool cubes. All the grow books and grow gurus say to keep the cubes moist, but not sopping wet. Well, with
rockwool cubes, that covers a lot of ground. I use a kitchen scale and try to keep the weight of the moistened cubes in the 40g neighborhood. I've learned that at that weight, they're not
sopping wet yet I can leave them for 10-11 hours while I'm at work and not have to sweat over them drying out. All four cubes went into a seedling tray that sat atop a heat mat placed in
a dark corner of my closet. A Mondi humidity dome covered the whole show. After a few days, all four seeds had broken the surface. Once all the cotyledon leaves were open and turning a
nice green color the dome went into the tent and under the light. That was January 17th.


I'm not sure when the right time is to move the sprouts from the seedling tray/humidity dome and into the Hydroton grow media but I make the move when the root just starts to reach the
side edge of the rockwool cube. I figure that roots are in darkness so when the root extends beyond the rockwool cube and into the light ... it's time. I moved the sprouts into the 5 gallon grow buckets on January 21st.


January 28th - 1st weekly res change. Switching from plain water to a 1/2 strength nute mix. The sprouts are showing progress, but no visible roots just yet. Shouldn't be long though. Res changes kinda suck, but I like to make the most of it. I'll usually put on some music, puff a bowl then start off with a fresh clean bucket full of tap water. I like to calibrate my pH meter with 7.0 solution first. It's never too far off. Then I take a baseline ppm and pH reading of the tap water. Vegas tap water is hard, but amazingly consistent. I can pretty much count on a pH of 6.5 to 7.0 and ppm of 485 to 500 year round. Today, it was 6.6 and 490. Next, I add nutes - Botanicare Pro Grow and Liquid Karma. Then I add H2O2. I use a 35% H2O2 solution mixed 10ml per gallon or a shot glass full per bucket. H2O2 keeps things nice and clean. Lastly, I measure the ppm again and adjust the pH with a few drops of pH down. I shoot for 5.5 to 6.0. This time, it came out at 5.7. Close enough. Wish me luck RIU and please comment or ask any questions you may have.

Here's a quick update... The plants are now entering their 4th week in the buckets. The Sour Jack sprout crapped out on me. It turned a pale looking lime greenish color not long after going into the bucket and just never did anything. I'm not sure what the trouble was since the others got the same treatment and have responded well enough. Oh well. I made the switch from the 250w CFL to a 400w MH light and the plants seem to really like it. Also made the switch from Botanicare nutes to Fox Farm. Anyway, all is well so far. Here are some pics. Take care RIU.

do you have everything right? ph/water temp/air temp/ RH/ PPM? they are so small for 4 weeks. they look good kinda like your ph is off just enough to slow them to a crawl.

This is actually the beginning of the 3rd week for the plants since going into the buckets. See my initial post where I said that I made the move into the buckets on January 21st.

have you grown dwc before m8, im trying in for the first time and had nothing but issues and slime so far. this my effort that went into the pot as a rooted clone on boxing day, 7 weeks ago.... talk about stunted growth... grrrr. either tapwater here in uk is shit for dwc or its me..... probably me haha

Thanks for your interest DCobeen. You know, that was my first thought. And while I do think that there is room for some tweaking, things are right enough for three plants it seems... That is, aside from the weak, sickly looking one that I yanked, the 3 remaining plants are thriving for 3 weeks in. See my earlier post for the time correction and my earlier pics for PPM and pH settings. I run PPM at 980 or so. I do res changes weekly. Temps are running in the low 80's with lights on and fans running and in the low 70's in the dark. I use an 18-6 schedule.

I'll take a couple of pics and post them in few.

Howdy DrOfWelshMagic,

Yeah, this is my 3rd go with DWC. Never had plants that looked like yours though. I'm no guru, but I would return to the basics. From that yellowing and overall lack of lush growth, I'd suspect a nute lockup. Calibrate those meters and double check that PH and PPM/TDS. I see your using H202. That's good. If I read the label correctly, you have a 17% solution. I'd be using 2oz of that for every 3gal of water. Here in The States, we have excellent drinking water. I live in the desert and drink lots of tap water. I figure that if it's ok to drink with and OK to cook with, then its fine for my plants. Still, companies earn millions from selling bottled water and R.O. systems. I'm sure that a country capable of producing something as delicious as Samuel Smith's Nut Brown Ale or their Tadcaster Porter using the available water has nothing to be ashamed of in their water supply. Here are some pics from my previous DWC grows.

you roots are dieing. you need to make sure you have all right. do you have air in bottom? it also looks like your water is to high you want 2-3 inches between the bottom of basket and the water. also add 1 tblspoon per gallon of water of h2o2 HP. this will help allot but first you need to change you res start over with it. also let you water sit out for a day in a jug so it get rid off chlorine.

OMG Im so jealous of those roots man... lol

hi m8 and thanks for reply.. my tap water is 7.3 and 60-70ppm out of the tap. I let it dechlorinate for 24 hrs before using it inc. any top offs I do. I have bottles of water everywhere lol. I have 2 cylinder soda can size airstone each running off its own twin outlet pump. I think the main problem is I have just been using the wrong nutes which had organic ingredients. advanced nutrients first, then GH flora nova. since I only used synthetic nutes (calmag/potsil) and Orca it seems to have improved tremendously. I have not been able to check today but am hopeful of vast improvement. will post a pic later

oh yeah, the photo was when I gave her a h2o2 bath, the level in my bucket is 2in below net pot base

Looking good man, im starting my 1st grow soon an looks close to yours with the tent light set up and DWC, looking forward to seeing your progress

Hopefully it will be up in the next 2 months still have some planning to do to get it ready, your roots are looking good! i just subscribed to your thread
 
Here's a quick update. We're on day 25 since moving the sprouts from the seedling tray into the DWC buckets. All three plants have now sent roots down far enough below the netpot to get their own groceries from the nute solution below. No more nursing them. Woo Hoo! I checked the pH and PPM in all three buckets and we are on the money...pH 6.1 to 6.3, PPM 980 to 1020. Here's some pics.

WOOOHOOOO well would ya look at that??? less than 1 week, still no food mind you, hopefully coming tomorrow, this is how she's responded to the fresh water and Orca regime.. Im so stoked after wastin the last 8 weeks fighting her, even without the nutes she's showing a nice new greenness to her.... suits her far better than yellow!!
