Will you be using coco for this setup? I've been considering doing a flood and drain set up with this Tent. Figure I can veg in here on a flood and drain set up and then move the plants to the 4x4 once I get that set up. 2x4 veg flood and drain and a 4x4 flower room either flood and drain on drip to waste. I have a 2x4 flood table coming in the mail this week so let's get creative

Yeah mate, coco/peri 70/30. Found a perfect pump on Amazon for £8.50. Was actually looking for a pump for my NFT res cos just realised my spare is fooked. Usually buy from a hydro shop but a quick look in the aquatic section and got the same thing half price with next day delivery instead of 17 quid and a fiver delivery. All I need now is the rings and I'm good to go. Gonna root them up for 2 weeks before I start flush feeding though. In rockwools just now so got plenty time.
I'm gonna do what my NFT does and just have a slow steady stream on 24/7 and see what happens.

Any worry of your Coco washing out of your pots? I was thinking of setting this up as a flood and drain and ressercualting my neuts and that way not have to worry about droppers feeding un evenly but biggest concern is the Coco washing out of the holes in the air pots and making the res to dirty.

fabric pots for me mate. Same benefits of the air pots but no holes for anything to fall through.

New flood table came in the mail.
A little smaller than I was expecting but should work out well for either a drip to waste or a flood and drain. For now I'm not going to drill out any drain holes and just continue to shop vac up the waste. Might build a small stand for the tray in the next few days but we will see.

So this morning when they plants got their first feedings I decided to pinch off some of the lower branches and leaves. The first sets since they have shown almost no growth and I know these usually never produce much. ALso took some run off measurements.

Water in
PPM 745
PH:5.9

Water out
PPM 346
PH: 6.2

I assume the lower ppm is a good thing since that shows the plants are up taking the neuts. But why the slight raise in Ph?

 

[Barney86]

What you mean by water out mate? Your run off? No way in hell plants that size can drop a 700ppm feed by half in any way shape or form so something's not right. Dodgy meter maybe?

 

[ClearCrow]

Yea run off. And the meter seems consistent every day I check the res ppm and they have always read +/- 2 or 3 ppm of the previous days. Unless the water level isn't deep enough to get an accurate reading.

 

[Barney86]

Hmm theres definately something a miss mate. When plants are fully grown they don't drop a 700ppm feed much. To cut it in half with seedlings just isn't really a possibility lol. Gotta give anything you're checking a stir first to make sure it's not all settling to the bottom. Dunno to be honest but the pH rise is normal.
That's what you want. If it's rising just a little bit then that's a good thing. It should naturally rise during veg then drop during bloom.
It's a good thing though, gives the plant a better range to absorb different nutes.
To keep it in check you feed at 5.7 for veg then around 6.2ish for bloom.
Only fluctuates properly if the feed strength and delivery is fairly sound though. 0.1-0.2 rise per day is pretty normal.

 

[ClearCrow]

I'll check the run off again at tonight's feeding and see what it says. It was probably just a poor reading.

 

[Barney86]

Ahh, have you maybe had it on EC setting? Mines catches me out now n again. EC is double the ppm so that would make sense.

Do you have any experience with drip rings? Right now I'm getting away with just using the bare ended 1/4 hose while they are small but I need somthing to disperses the water more evenly around the pot. Was thinking of running a second hose and then T'ing them both off to distribute 4 streams to the pot. But also saw thses 6 and 9 inch drip rings on the ebay.

I’ll be setting up an irrigation system with those next week. I got 6 of the 6” for veg plants and 6 of the 9” for flowering plants. I posted the setup in my grow room build journal a couple days ago and I’ll have pictures and feedback on them soon if you’re interested stop by.

I don't think I have settings on my pen it's pretty basic.

Thanks for stopping by. I'll make sure to check in with your journal and updates.

Just stopped in at a buddies to check out so some lights. He lent me this 350watt to test. Also has some 600 watt versions of the same light I might pick up eventually. Unfortunately it's got one blown cob. Still a upgrade to my Amazon light I'm sure. I'll try it for a few days and see if I like it.

Size comparison between lights.

 

[ClearCrow]

Going to give it a test.

 

[ClearCrow]

Tonight's feeding brought to you by a dab of G-Berry, kind extracts.

 

[ClearCrow]

Same deal as before. 780ppm in res. And runoff 430ppm

Had a small scare this morning. Apparently when I switched lights I forgot to hook my humidifier back up properly. I use to have it hook up with the light timer so when then lights turned off so did the humidifier well when I switched lights I must have plugged it right into the power bar for some reason and well it didn't turn off when the lights did instead it kept running all night and when I looked in the tent at lights on this morning it was so humid that my mom did thermostat couldnt read the Rh it just said - - - and when I cycled thru thr min max it said max 99 so it was obviously over 100. So I turned my exhaust fan on for a few hours and turned the humidifier off. Room humidity is back under control and I really hope I didn't fuck to much uo with that. Luckily it was only for 6 hours and not 3 days

 

[ClearCrow]

So the timer I plugged the humidifier into was on outlet mode and bypassed the timer and ran all night again. Opened the tent this morning to again a rain Forrest. Hopefully these two excess humid evenings don't cause to much damage. Luckily plants are not flowering.

Two of my clones were showing roots Tru the rockwool cubes so I potted them up. Hopefully they jump back to life soon they are all looking rough.

I've also noticed the plants verticle growth has slow down and they are just starting to bush out. Fan leaves are all the size of my hand and the shoots are all starting to stretch up.
