Some things that have worked for me in coco for fungus gnats: A small amount of hydrogen peroxide in with the nutes. Extremely effective. Mosquito dunks dissolved in nutes. Takes time to work and needs to be reapplied. Organic. I'm pretty sure I used Spinosad once years ago and it was...

I buy cheap tents and drape black plastic over the exposed walls.

Just looked at the Luna chart for Binance and the hilarious thing is that if you'd taken a risk yesterday and bought it right at the bottom, you'd now be at over 10,000% profit, lol. Gotta love crypto.

Measure what it sees currently at 45 cm. Lets pretend it says 600 lux. 300 lux is 50% less than 600 lux. So you would set the calibration to -50%. Then you will see 300 lux next time you measure at 45 cm.

Thanks man. I ordered a few metres extra of the 3mm line so hopefully that gives me a level of flexibility. I'm just all about accessibility for this next run after the scrog before it where I couldn't access anything at the back. Any idea what's the longest run of 3mm you can dependably use...

I made it to about page 20 before I ordered a set for the next run :) It will be 5 plants in coco in a 3x3. My question is, what happens if I need to take the plants out of the tent? Can I take the carrot out temporarily and carefully reseat it when the plant goes back in the tent? Maybe stick...

I would install a ppfd app on your phone. They're not always accurate but it should allow you to calibrate the levels. Take a few readings now at the highest buds. Then with the new tent filled, mess around until you get those same levels.

Maxigrow/Bloom in pure coco here, but I've taken to adding the following Seasol - a liquid kelp, used as ph up. Hy-Gen Budlink - I thought I was buying potassium silicate but it appears to be a different form of silica because it doesn't send the ph shooting up. It's effects show very rapidly...

Yeah PM was my first thought too. Hopefully it's just residue!

What's up with the upper leaf in the first pic? Is that white stuff residue from a foliar spray?

Was the box in the shed? Or you got nervous about the police and got rid of it or something? Glad you are ok.

Lookin' good man. I'm nearly finished my first LED harvest now and struggled with the lights in both flower and veg. Recently got a cheap bluetooth lux meter and it was an instant relief. I had both lights way too high and shaved ~180 watts off my power use across both tents and the plants look...

I wouldn't call those fails, mate. Apart from being small and lacking in smell, they look quite well grown for a new grower, especially under a hot 1000w hps. How big is your tent and what's the ventilation setup look like? Best of luck for the grow.

I got that same gun recently. Do I understand correctly that you use the leaf temp to calculate VPD and not the temp from a hanging sensor at canopy height? Can really see the buds leaning over with weight in the last shots. :cool:

Can be either really. Just my opinion but I wouldn't sweat ph/ec of the runoff too much. You don't need meters to work out what's happened here, and fixing it is generally straightforward (lower the ec). It's good that you've picked up the problem quickly. What I do in a grow is start off with...

Something is not making sense here. I've never gone over 1.5 ec in coco so that seems pretty crazy they'd recommend 3.0. I haven't used those nutes but I have a very hard time believing those guys know what they're doing. Also I think the runoff PPM line is a typo? Take a zero off each of them...

I would look into a decent size deep cycle 12v battery and charger and run some 12v CFLs or LEDs directly from it as required. Mostly just to keep them in cycle, more than providing growth.

About 7 to 8 billion years until the sun burns out.

That's what I did, I'm on the last 2 weeks of my first led grow and pretty happy with it. It's certainly very uniform growth across the whole scrog screen. Light is a Mars fc-4800 and it's physical dimensions are pretty close to 3x3 so it also helps a little to stop the tent walls sucking in so...

Yeah I had it happen a few times but it was pretty random, just one here, one there. Eventually stopped using h2o2 and it stopped happening. Your theory probably makes sense too. Maybe sterilize your snippers. Ahhh! Clonex! Cool, now I can sleep tonight. :blsmoke: Well I'm subbed so I look...
