Hannabis Cannabis - DWC - LED - 1st Run - Picture Intensive

Day 8, 10-17-2014
Day 5 from sprout

Added a tiny bit of PH Down since the res PH was at 6.5, is it normal for the PH to keep going up everyday? I keep lowering it and the next day I find that it's back up again.

Added rolled towel for humidity, and temporary foil cover to prevent light from going through

Leaves are getting bigger but may be yellowing a bit? I'm guessing this is from stress from moving it around too often.

I felt the rubber hose today and it felt a bit slimey/slippery.... is this normal? I'm going to guess that's algae trying to grow so I put the foil over the hydroton to ensure no light gets through. If anybody knows the culprit feel free to chime in.

 

[hydrofun]

Try adding aquashield or hydrogaurd both are made by botanicare. That should fix your problem with slimy water or algae.

Day 11 from seed - 10/20/2014
Day 8 since sprout

Here are the 5 ladies, the last one is a runt and barely growing the second set of leaves

Going to wait until the runt gets it's act together and fully grow the second set of leaves then I'll start adding nutes.

 

[HunterHunt]

Your girls are just now STARTING to get there first set of leaves. The first two sets are not true leaves. No nutes are needed until 3 or 4 sets of true leaves. You still have a while to go before adding nutes. You can introduce them to around 100 PPM of nutes around 2-3 sets of leaves and would personally not go over that at that time.

In DWC little nutes is better than full nutes.

What is your pH of your reservoir?

What beneficiary bacteria are you using for this grow?

 

[GoogleGenie]

Looking good dude!

Just a heads up, you probably don't need both your LED lights on for this phase of growth (seedling/early veg), one of them is probably enough, and you probably wont need to flick the other one on for a good few weeks. Plants in veg dont need as much light as they do during flowering, and use predominantly blue light.

Just my 5 cents, Can make all the difference to your electricity bill

Looking good though dude, and keep up the good work

pH is hovering around 5.7-6.1, I don't think I'm using any beneficiary bacteria? I haven't read up on that at all. It's at around 170PPM right now due to it being tap water.

I'll take one off, but won't that shock the plant?

 

[HunterHunt]

The reduced light will not shock the plant to my knowledge. For vegetative growth you dont need much light. I usually veg under 3-6 small 23 watt CFL's and they do wonderful. Flowering and when you switch to 12/12 is when the wattage is needed to form the buds. One of your LED's will be sufficient until you flip to flowering.

For beneficiary bacteria i personally use Aquashield by botanicare. Theres a lot of products on the market like great white, z7, and more. Your DWC plants wont survive if you dont run either a beneficiary bacteria or a H202 substance in your reservoir. The bacteria is the easiest and best way to go and your girls will thrive on the solution. What happens if you dont run one of these methods is your roots will either get slime, root rot, or algae on them and it will kill them. A must for DWC and hydro!!


Tap water is all i use and mine is also around 120 ppm and that is fine. I just wouldn't add any nute products until the timeline stated on my last post. I let my tap water sit out uncovered for 24 hours so the chlorine can evaporate out and be less harsh.

Im subbed and will follow along! Good luck. If you have any questions ask away we will try to help you here and you are at the best place!

I'll get some Aquashield (Hydroguard now?) today and change the res tomorrow. This is the hardest part of the grow for me because my tub is 30 Gallons, with 5 plants. I also have the water recirculating up the net pot so I have to clean all those out as well. I'm thinking of getting a few 5 gallons container to pump the water into the res, I can't carry 30 gallons of water in one go haha 200+lbs.

I just lowered the light to one 300w LED panel (about 170w real output). does it matter that I have 5 plants growing? I feel like if I lower the light to only 1 LED panel I'd have to also raise the panel so the light distribution is even. I saw that yours was only in a 5 gallons container and with only 1 plant.

 

[Dusty Kiefers]

Ive run dwc for years I've never used bacteria never had a prob. Dont see use in it scince I change water every 7 days and would kill it.

 

[hydrofun]

Beneficial's like Orca/Great White only last about 72 hours anyway just add them it helps the root zone.

How is changing the reservoir going to kill bad bacteria on your roots, rockwool, and hydroton? You must be adding or cleaning with H202 (hydrogen peroxide). If not then you have been lucky!

The few people that i have seen not use either beneficiary bacteria or H2O2(or bleach) always had to run water chillers and still in the end had problems. Its only a matter of time before the conditions are right and it effects your plants. And plus the roots love it and you will see higher growth rates and bud production by using beanies! Also, once you get bad bacteria(root rot) in your reservoir and root zone even after a reservoir change within 12-24 it will be effected again.


archie, You do not need to change the reservoir! Just add the hydroguard at 5-15 ml per gallon. It last for about a week. I usually add it as directed every 4-7 days. I always only add around 5ml per gallon and my reservoir temps hit almost 90 degrees during the day and never had a problem.
Also, one light will be plenty even for 5 plants. Once they start getting bigger you can make the call to add another one but this early stage one is plenty. There is a LED guide to the distance it should be from your plants and it looks like it should be around 18"too 24" from your plants. Maybe a LED specialist can give you more tips on this.

hydrofun, great white last about the same as aqua shield which states to be added every 4-7 days. Great white is to expensive for me when aquashield is working for me right now! If i was going to brew a tea then great white would be one of the additives!

I feel like if I lower the light to only 1 LED panel I'd have to also raise the panel so the light distribution is even. I saw that yours was only in a 5 gallons container and with only 1 plant.

If i were you, I would raise your light so that the light is distributed evenly over the tub, at a guess, i'd say 3-4ft(90-120cm) high.

Then use the internode spacing to judge how far your lights should be as the plants grow more nodes (you can probably tell when you have 4/5 nodes), if your nodes are far apart, perhaps the light is too high. Eventually you will get to know the ideal height, which helps with regularly adjusting the high of your light. By doing this, you can control your internode spacing (somewhat). Don't get me wrong, a lot of factors contribute to internode spacing, especially temperature, but the height of your light is one of those factors.

I agree with HunterNitro, definitely on the lighting, but most importantly on the bennies, you definitely want to be using some sort of bennies (IMHO), personally I use Great White Shark. I use it in every single seedling/clone/vegetative feed. In fact, early on I literally sprinkle it on the roots and they love it. Bennies are a must. I've grown DWC with and Without it, and you can literally see the difference in root mass for starters!

Note : Your roots will love the H202, but the bennies, especially Mycorrhizae (Great White Shark) won't because the H202 essentially kills them off. So best to use one or the other. I favour Great White over H202.

Just put 2ml/gal of hydroguard, which the owner of the hydroponic store told me was the same as aquashield. Hope it'll do better. Temp is at 80F humidity is at 35%. Nothing much I can do about that. Budget is running low

 

[hydrofun]

72 hours is what 3 days? ya so on the 4th day add more to stay at optimal levels. Like I said adding it 2 times a week after every 72 hours wont hurt and your roots will be huge. I run aquashield once a week and orca 2x a week now.

 

[HunterHunt]

Awesome archie! Glad you got some. Dont be scared to use it as I sometimes put 15 ml a gallon on hot weeks. You cant put to much that i know of. The roots love it and believe the would grow in straight aquashield lol. I know things can get expensive though... Especially with a 30 gallon reservoir!!! 2 ml should be enough i hope!

The bottle itself says 2ml/gal maybe the new hydroguard has a more concentrated dosage than aquashield?

 

[HunterHunt]

I have read where hydrogaurd says 2 ml on the bottle but the website actually states : Hydroponic Applications: 5 - 10 ml/gallon. If you bought a big bottle and have enough i would add at least 5 ml per gallon. You can make the call though you have a large reservoir!

80f sounds about right.

It's the day and night temps that affect internode spacing. If there is little difference between your temp at night (lights out) to your temp during the day, this promotes tighter internode spacing. The bigger the temp swing between the two, the bigger internode spacing will be.
Good ventilation and extraction from your grow room will take care of this.

But don't worry about tackling this all at once, it can get very expensive, over time you will enhance your grow space to how you want it. That's most of the fun
