Very curious to see how you doHello all and thanks for taking a look.
Well, Let me tell you all about me. I've grown many outdoor grows over the years and after reading up on this site for the past few weeks, I've learned that it's actually unfathomable that I ever managed to get anything to grow let alone the yields I've pulled over he years.
So welcome To my noob experience with DWC topfeed. I built my own res from 10gal tubs with a manifold and pump. I have a double feed air pump feeding two long triangle shaped air-stones per tub(all 1/4" tubing is black) and have the drip feeding into 6 3' net pots per lid. I'm growing in a 4x4x6.5' tent with a 4" inline w/ carbon filter fan on a controller with 2 different brand led 600w panels one with bloom/veg options and the other with "full spectrum". I'd like to see which side ends up performing better and expand my collection from there.
Space - 4'x4'x6.5' tent
Lights - 2x 600w led panels 246w and 180w draw from wall
Room temp - 72f-76f
Room RH - 45- 55 %
Air movement - 1x 6" usb fan and 1x6" clip on desk fan and a cool mist humidifier.
Exhaust - 4"inline w/carbon filter in tent
Media - Topfeed DWC hydroponic in 3" net pots with rapid rooters and hydroton
Nutrients - Flora micro, Flora gro, Flora bloom
Supplements - Hydroguard and SM-90(i know they are to only be used alone as one effectively kills the other but
I wanted to have anything I need on hand.)
PH control - Ganja express ph up & down digital ph meter
PPM monitored - yes
Water used - Tap that sits for at least a day with its own air stone that bubbles off the chlorine and regulates the
true ph.
Strain - Burmese Kush (BuKu)
Type - Hybrid/indica dominant
Height - upto 100cm
Flowering - 7-9 weeks
#of plants - 6 seedlings/3 per tub. (fem seeds germed in rr in a dome. 6/6 on my first try)
Current week of growth - 3 days since sprout
Light cycle -24/0
nutrients - Ph'd water and hydroguard for week 1.
Current ph - 5.65-5.75
Topfeed - 24/7
So this is my setup, its all from what i have cobbled together from a few weeks of reading what you fine folks have done over the years. I only hope for half the skill of any of you and i'll do just fine. One I figure out how to upload pics I have some that are from their first few days and i plan on taking a ton over the process. hope to have some ofyou along for the ride and happy growing!
If youre worried about funky tubs, put a quarter cup of 3% peroxide in the day before you do a nute change. Be aware that peroxide will kill everything... bad stuff, but also beneficial bacteria, etc. If your using mycorrhiza, or something like that it will have to be replaced. I run an RDWC. Peroxide is great, but there are compromises
Hydroguard is the goods!
That's awesome. I wanted to share how I got over water temp issues without a chiller... I cut a 6inch hole in my res. lid. I then placed a 6 inch inline fan in the hole making sure it wouldn't fall through (I took some air tube and taped it about 1 inch from the bottom of the fan to ensure it sits on the lid correctly). Then I just set the res. lid on the tub so the air can escape. This is good for a 10 degree drop amazingly. This trick is used on aquariums. I ended up hooking up a 6 inch duct from my AC for a deeper drop. I also put another 6 inch hole in the lid and added a 6 inch elbow so the cool air is still a benefit to the room. I run my room at almost 85 degrees as recommended by my LED manufacturer.So it took me the whole damn day just to get it ready to test( which it failed miserably lol) but it's assembled and the silicone is curing as we speak. Here is my version of the Rider809/Scrogdawg RDWC System.
Hey man Thanks for checking out my journal.
They are going off...Hey man Thanks for checking out my journal.
Today the girls got a day to themselves while I built their soon to be babies new home. I'm pretty friggen pumped about the new system and can't wait to clone off the strongest lady of this batch for my first run in it. I finally topped them tonight after the build was done then readjusted the lst and have a pretty flat set of girls bushing out rather nicely. Ph was at 6.2 and 6.3 so i dropped it down to 5.7 and 5.6 in the tubs. water temp is holding pretty decent at 68-69f which with the hydroguard I feel like i have a rocking root network,
and heres they are topped and strapped down,
I'm still using the humidifier but i'm only having to fill it every 36 hours instead of 24, my controller shuts it off above 55% and turn it on when it drops below 53.5%. I have been able to slow my fan down to minimum now that normal Canadian temperatures are showing their face and I don';t have t run my AC in November. I will note some of the older leaves have some little brown rust spots on them from earlier phosphorous deficiency but I haven't seen any new spot on any of them so hopefully that's taken care of. With the rate of growth i'm thinking I'll flip at day 35 and flower for the longer end of the 8 week flower for this strain so I can get my new system in the tent pumping. Anyhow I'm beat and for letting me work uninterrupted today I am getting up early to make the wife breakfast before she goes to work this morning so I need to hit the hay. Time for a bedtime bongrip
Oh sorry... "going off " means they are doing very well. I guess that could sound like a bad thing if you haven't heard that. You're doing a fine job and your plants are proof.
"Going off" is a Hawaiian term used for epic large surf. There's a little more to it, but I'll spare you. For the record, I'm not Hawaiian, nor a surfer. I was a "sponger" (bodyboarder) here in Southern California, but that was 100 pounds ago. Ha Ha.
Nice. I'm very impressed with your new system. Looks like an Undercurrent minus the crazy cost. I wish i could share pictures, but i think I'm still too new here. I don't have permission rights.
