I started three seeds. Two are female. Two weeks later the third plant isn't showing sex. Will something happen eventually or do some seeds never show sex?

Getting clones to root doesn't require nutrients. What function does PHing clone water serve?

I use clone kings too. Picked them out for cost and tray design. I've replaced one of the manifolds with PVC, also a bigger pump. It works fine with the included equipment but the PVC is a slight upgrade. Would have been better without the net cups but I cut the bottoms off and it gets the job...

Thatt's right. The fan/filter need to be paired by airflow. What I've done in the past is oversize them and use a fan controller to dial it down to desired temps. Easy. It costs a little more but the filter will last longer and the fan is the least of the cost.

Like some people suggest with wood slats and zip ties, I use aluminum angle. You can get it at big box hardware but if you have a metal supplier nearby it will be a lot cheaper. I don't remember what profile I used but whatever is smallest will work fine. It doesn't need a lot of strength. With...

I started out using a manifold, mechanical controller and repeat cycle timer. Eventually I switched to digital and the tanks started lasting at least twice as long as before. It would have been good to know what the CO2 levels were with the mechanical setup, but for the price of a CO2 meter it...

I have two aeroponic cloners so I can get rooted clones pretty often. I start plants in 12/12 once a month roughly so always have more clones than I need, which is the point. But if you're constantly feeding new plants into a perpetual chamber (and growing from seed) start new plants at the same...

What size tent? And multiple tents or both fans in same tent?

Yea, I asked about that but it wasn't addressed. With a good exhaust fan and "freezing" room I would expect the tent temps to be lower than 90.

I know someone that would grow two plants in each hydro bucket. They were switched to 12/12 when still small and ended up taking up the same space a single plant would use with more veg time. This allowed him to use a smaller space for vegetative area. I never got into whether he did more...

Yes it did, but dry air is easier to cool. I can't say exactly how it affected the electrical efficiency but the overall effect was cooler temps along with drier air. It might be worth it to run the dehumidifier with the AC for a few hours to see how it affects temps and humidity since you...

So low oxygen and possible anaerobic activity. I had an air pump go bad once, plant looked the same. Never recovered. How long has the plant been wilted since fixing the oxygen issue?

A 60-70 liter dehumidifier is going to remove a lot more moisture than a window unit can. Dry air is easier to cool so it should offset the power being used by the AC. Not sure about the tent temps being so high. What's the fan volume and tent sizes? I had similar problems when I was growing...

In my experience the top node will still be apical but it won't be as prominent. That's why people LST. Once the symmetry is gone it doesn't come back.

I don't see any heat stress. I think the chance of that lamp causing direct radiation damage will be very low. Keep the ambient temps in the right range and it will be fine.

I think the floor treatment is being helpful but you're right. I have managed this whole time to keep things under control and get good harvests but it's very difficult in this environment to eradicate them and I'm very tired of dealing with it. I may try another method, but a deep clean is the...

Ahh, good to know. I feel like most of my gains have been in the last month after I started to drench in early flower. Hopefully once the mature plants are harvested that will be it. I've been treating the floor (using a mop) with stronger insecticide for several weeks. I'll try citric acid if...

If you have eradicated a mite infestation, give a short explanation on how it was done. Infestation #1: limited to veg area. Used Doktor Doom (pyrethrin) fogger and then repeated 3 days later. Problem solved. Infestation #2: In perpetual flower area. Can't fog so have been using a pyrethrin...

I have read 11 days, 14 days, and apparently eggs can hatch at up to 20 days. However, I have in the past defeated mites with Doktor Doom, fogging the veg room and following up with a second fog three days later. Perhaps the fog (pyrethrin) can permeate eggs? Or perhaps they typically hatch...

My understanding is that organics are primarily food for the microbiome. I wouldn't use organics in hydro without adding beneficial bacteria or fungi. That's just asking for the root problems. After doing this for many years I've started using a microbial product called Azos in the aeroponic...
