NFT MD300 autoflower grow

[Redeyed84]

Going to start a journal on my 1st auto grow and my 1st run in my NFT system. I'm going to be growing 20 plants will try and update as often as possible and hopefully will get some help along the way

FAST BUD'S SEEDS
x5 girl scout cookies
x5 west coast OG
x4 LSD25 (1FAILED TO GERM)

And my world of seeds freebies from herbies
x3 northern light x big bud
x3 coffee Ryder

Total system size 6 1/2ft by 5 1/2ft
Tray size x2 5 1/2ft by 3 1/2ft

Lighting ..x2 600 watt HP's over one tray (10plants)
1000 watt HP's over other tray (10plants)
6" Intake fan direct from window for fresh cold air
8" fan and carbon filter sucking out of room into attic/loft
x1 osilating fan for air flow along canopy
Feed will be dutch pro grow A/B and bloom A/B with dutch pro Explode towards the end ..
Here's a couple of pics I hav just to show roughly the set up..
Thanx for taking time to read because it took some writing haha.

 

[Doo-flop]

I'll watch this with you, hope it goes well

Well nothing much to report other than the temperature in my reservoir iz hitting 26° and with no more $ im having to use frozen bottles ov water wich are working but for a very short time. Need to tey amd fix this b4 plants get bigger.

I made a chiller out of a free water cooler I got from a place I worked. Fountain pump in the rez circulating the nute mix through 3/8 tubing coiled in the chiller tank of the cooler. Had the tubing already so it cost me $14 for a little pond pump. Filled the tank on the cooler with antifreeze as it froze the water I started with.


Used a glue gun to cover the pump with mosquito screen to keep the roots out in my DWC tub.



Here it is at work.



Can do two tubs and still have reserve to do more.

ISo this is my quick fix just set it up picture quality not the best .will check on rez tomorrow see if it has helped lower the temperature only problem I may have now could be room temperature since I'm teeing of from my intake fan but I'm not to worried at the minute plants look fine (i think) checked cubes tape root has made it out the bottom of the cubes and is hitting the spreader mat.. My girls will be a week old on monday (from germ).
Happy days .thanks again peeps

Do your windows look like that from the street?

I like the setup you got there and drew up a design for what I called a gutter grow to set pots in gutters with nutes flowing down to water them or net pots that get started in DWC to get enough roots to lay in the flowing nutes. I think it would work great for autoflowers. I'll post the drawing so it's easier to visualize.


Just an idea that doesn't really fit into my space.

You may need to cut down on some wattage until you get your temps figured out... those res temps can cause a lot of problems... is there a way to hang your filter higher so it draws more hot air... also reflectors direct heat right at your plants.. have you ever seen a bare bulb grow? Just throwin out options...

That's a nice looking system VERY similar to my NFT same concept.

No my window has new blinds up and looks like a normal window

Temperature in system since putting ducting in has dropped to 20° which is a lot better and also The temperature in the room is sitting at 24°
Room temp 24°(75f)
Minimum 17° (62.6f)
Max 25° (77f)

Overall I'm pleased with that will be looking at trying to raise carbon filter and lowering rez a little bit more.

 

[HydoDan]

Those temps are good compared to where they were...sounds like you've got a handle on it...
I've had rez temp issues and root rot was the end result..

That's my main worry but if I need to i can put my fan on the second setting which is stronger but quite noisey And not ideal so hopefully I can lower rez temp without upping fan speed.. My only other issue is with my carbon filter/fan when its on and the room door is closed it makes a loud noise (not the fan amd filter) like a whistling sound similar to wind so i think i may have to drill some holes in bottom ov my door and put like a grill across so it allows more air in as I think that the room is that air tight its causing the whistling noise again not ideal for neighbours.

 

[HydoDan]

Neighbors can be a pain in the ass... I have 13 acres so mine aren't too close... and I'm legal..
Even tho it's legal it still has a stigma attached... not really socially acceptable.. yet!
Hope you get that annoying whistle solved...

I have the same issue with not enough holes to let air in too RedEyed. Got some grills at the local farm supply that are about 4" x 16" and about $5 each. They got mosquito netting on the back and I put a layer of those anti-static wipes on that then screwed them on holes I cut in a panel I made to enclose the space under the stairs in my basement where the sump is. Bugs breeding in there so now they can't get into the grow room. I cut the holes with a jig saw so they custom fit the grills and allow max air flow. With one of those each side of your door it won't look odd at all.



Used that thick, clear tablecloth plastic to make a window so I can easily check the sump without taking out the 16 screws that hold that panel on with weather stripping all around it to get a good seal. Since that pic was taken I put two more grills on that panel and now need to drill some holes in the risers of the steps to let more air get under the steps to those grills.

Meant to mention that you can put a speed controller on your exhaust fan to make it run quieter and still move a lot of air. You can buy a cheap one for around $30 or make your own from a ceiling fan controller. Not a dimmer for lights tho. The ceiling fan controllers are about $15 and then you need the wall box to mount it in and power cords on each end. Other than the controller I have all the other stuff lying around the shop so you're probably better off just buying one.

Mannn you got it good @HydoDan grow free Hassel free environment no such luck for myself YET ha.. Thanx mate holidays from work next couple of days so will spend some time on temps and whistles ha.

 

[Redeyed84]

@OldMedUser some great work thee very handy around the home I take it .. Good job my friend and I guarantee the air flow and temps are spot on now..i myself welllll I'm not very good at the old DIY ha but I'll nock a few holse in the bottom of my door and put a similar grill to yourself and do some test whilst I'm off work and get things abi better again.. Always room for improvement then its just waiting game for my girls to start growing.

 

[Redeyed84]

Couple pics of my girls ones slightly yellow and 2 unique/disfiguered ones ha ..again sorry for poor quality pics camera is rubbish at the minute
These are around a week old since they popped their tape root so a week from germination and I think about 4/5 days since popping thee heads out of the seeds.

1st 2 pics are the diformed or whateva u want to cal them ones then we have
Coffee Ryder
LSD25
West coast OG
GSC

THANX AGAIN

Nice strains! I bought a gram of GSC from a dispensary in BC when I was out there in August. Didn't like it at first but after a couple more tries really enjoyed it. Should have took the $30 deal for 4 grams I was offered.

I have a cross of LSD and Blueberry both from Barney's Farms about 6 years ago. Wonder if it's the same LSD you have. Great cross that I'm just about to plant 30 or 40 beans of.

Your plants are still chugging along and looking a little better now. Another week or so should tell.
