I have a grow that didn't do very well. After 6 weeks of flower it looked about 3 weeks in. So, I re-vegged it and after 2 weeks it doesn't look much different. Is it too late? Do I get rid of the plants? Thanks!

Wow, that's odd. The biggest air pump around me is 10L/H with 4 outputs.

The air pumps I use for my DWC are 5L/H. Someone told me that the optimal amount of oxygen is 1:1, so for my 50L reservoir I would need 10x as much. What's the truth?

Ever since I started growing in Hydro, I've been getting mealy bugs towards the end. I've read that you can use Neem oil but not in flower. So, how do I get rid of them?

Wow, I hadn't thought of that. I am revegging them because I want to either use them as mothers or take clones when they are big enough. Are you saying I should clone them now to avoid the possibility of cloning them after they hermie?

So, I have taken apart a small fridge and now I'm wondering what to do with the condenser coils (the part that gets hot to remove the heat). Am I just supposed to run a fan over it and put it on the wall?

So, what makes a regular plant more prone to becoming a hermie? I never had to deal with this uncertainty while growing feminised plants.

Lol. How do I tell? That's my problem.

So, the last plant turned out to be male. What about these two? There's also the possibility that they're hermies, right? The idea was that I'd figure out whether they were male or female by flowering them. That way, I could return them to veg and use them as mothers. So, I need...

I would prefer to maybe reuse a small AC? That way I can have the heated portion outside the room and cooling portion inside it. Any ideas?

I've got a large AC but since the temps have gone down in the past month it's not necessary and it's kind of suspicious to turn it on. I know there are dedicated water chillers but they're really expensive here ($500 and up), so is there anything you guys use to chill your water besides that...

I've got three plants flowering in a closet with a 120w LED. I think two of the plants weren't getting enough light, so I moved it closer but they aren't getting better. Any ideas?

What are you guys basing this on? There definitely are types of lights that scale down to 60hz instead of 120hz when lowering to 50% thereby increasing its lifespan by two. I have a socket power meter. I'll let you know if it decreases power or not.

If I get a 1000w bulb and run it at 50% or 75% will it last longer than if I run it at 100%? I'm curious because I've already got a 1000w ballast and 1000w bulbs are roughly the same price as 600w bulbs near me.

It seems like the PPM in my reservoir goes up after leaving it for a few days, instead of going down. Using R/O water with a PPM of ~35 and nutrients to raise the PPM to 400, the PPM is now 800 in one reservoir and 1,100 in the other. I put the same amount of nutrients give-or-take in both...
