PH is dropping from over feeding. IME in dwc no higher than 1000 ppms was ever needed, in dtw coco I don’t go over 800 with multiple feedings and that’s still too much most of the time

Inzane in the membrane by the ethos collective

Just RO water with three drops of bleach per gallons/ cut stems on a 45 degree angle below a node

Hands down the simplest way to clone is put ur cuttings in a cup of water on a heating mat. I put a bunch in a cup to shade where the roots will grow. Heating may set to 78, if your not using city water, add three drops of bleach per gallon to keep everything sterile. I get 100% rooting this way...

Good air circulation is a must either way

You could do two luminus cxm22s and a hlg 185h c1400b for 90 bucks...add some pin heat sinks for another 40 and you would have a more powerful light with a better spread for cheaper

Those are not CXB3590’s like the optic uses. Not the most efficient

I run 18/6 but 19/5 works or even 20/4. I like to give my plants some rest everyday

Don’t kill them with light in veg, hopefully u can dim your light. too much light and stems start turning purple and leaves turns pale and droopy

I seem to get more weight with the 3000k

Depends on the size of the tent

I run an electric oil radiator with a piece of tape over the on light. I use it to get temps up in the day and keep my day/night temp difference to a minimum.

Turn off

That is more than enough light for a 4x4, wattage wise. the problem would be getting an even spread with an odd number of cobs

Is there a day and night setting? I’m really trying to keep my temp difference to a ten degree minimum. Trying to limit the stretch on two insane in the membrane. usually deal with about a 20 degree difference which I feel makes most strains get too stretchy

I was looking at those... how do they work? Do you have to mount the fan/thermostat in the tent? Turns out using a heater to control night time temps keeps the humidity from spiking

What is the new fan speed controller that you got? I’ve been looking into a new controller to combat high night time humidity.. single speed 24/7 isn’t cutting it

Is that ocean forest dirt? That seedling does not look happy

You could run two 44” strips the fb24b’s on the hlg 240h 48b wired in parallel. Mount them on some 2” by 1” 1/8” thick aluminum u channel. Space them 24” apart and hang them high

Just like coco, RW maintains adequate levels of oxygen in the medium. Wet/dry cycle is more for soil grows, there is still somewhat of a wet dry with dtw but not as drastic. For me in coco it’s more of a soaking wet/ wet cycle. Dtw in any soilless medium is hydro and should be treated...
