If there are any electrical experts on here I would like to know if an old computer power supply would be suitable for powering LED lights? I know they are pretty beefy at 400 to 500 watts and I would like to use LED's to get to this level. I think that full spectrum is a step backwards as the...

Can you tell us your source for these predators? Cost? General area (East Coast, West Coast, etc.) as I would think you would not want to ship these across the country? And of course your satisfaction with the results.

You can use a dish or bowl of apple cider vinegar to attract them. Also, if you keep the roots underwater, with oxygenated water there is enough O2 for the plants but not for the RA. I have seen people use dry ice in DWC systems to gas them with the C02. They are hard to fully kill off as...

I put some ground cover cloth on top of the container and ran aerated water through. This is like half hydro and half soil. The goal is to keep the soil wet enough that the RA can't breathe but enough O2 in the water for the roots. I also put a bowl on the top with apple cider vinegar to...

Consider using a larger starting container or pipe the main container into another container entering high on this second container. Then also high on the second container connect to your delivery system with the gunk caught in the second container.

About using the Azmax in the water....not sure that it has any systemic power but maybe it is moving into the air somehow. So, not sure if you are on to something or just lucky so far. If it works after an infestation that would be a more conclusive result. Hopefully for you, you just never...

I am experiencing spider mites in flowers. I don't like the idea of using pesticides so this is what I am thinking: - get a cool mist humidifier and fog the grow area - possible formula one - isopropyl alcohol and H2O2 - possible formula two - rosemary oil - possible formula three - habenero...

I did lady bugs and not much help. I am now working with lace wings. Still too early to tell. But I think they may be a good idea to just introduce every few weeks to keep the spider mites under control. I really want to avoid using poisons if possible.

I got the Bayer too. But after looking into it more I decided against it. It seems that the bee dying may be related to imid. But I was able to take out my root aphids by mechanical means. I took the pot with soil and covered the top with ground cloth (the kind used to keep weeds from...

I also have had root aphids. First in a hydro setup and they would eat on the roots that were above the water. Now I have switched to soil and they persist. I have put that soil ground cloth used to keep weeds out of your garden bed to close off the top of the container so they are somewhat...

I dealt with root aphids. In the DWC hydro the area above the water line up to the base of the plant was being affected. I use GoGnats in the reservoir and it took them out. I will put in a fresh nutrient solution at the end of two weeks. Most of the smell of GoGnats has abated. It has...

Mixing the two kinds of light should work. The LED's will provide narrow bands of the light spectrum and the CFL should provide a spectrum of light and help to fill in the middle areas of the light spectrum. Let us know how it turns out.

You might try putting a bit of the nutrient solution in but doing a lot could harm the plant more. It may not have any nutrients left in the larger leaves to power the roots and get the whole thing going.
