You probably won't find my lighting arrangement ready-made. I added a 500mm x 150mm cooltube to an Adjust-A-Wings reflector to get what you see in my op.

First, kill all the capitalists. ;) Second, ban the secondary trading of stocks (purchase from the issuing company only, sell back to the company only); make dividends the only legal profit to be made from stocks. Third, nationalise the banks and regulate them to within an inch of their...

no worries. I'd turn down the paranoia about cop helicopters unless you're growing outside. The best cure for paranoia is more info. If you're worried about FLIR, just hire one and look at your place. If you don't like what you see, you can do stuff to fix it. Prevent the walls from being...

No plant needs watering in lights-off. No need for a long dark cycle when switching from veg to flower. Just switch to 12h. A long dark cycle will not stop stretch. Stretch has a few causes, from low light levels to excessively high air temps. If you want shorter plants, just don't veg them...

Roots don't like light- of any colour. Keep at least 20 metres of separation between your plants and LEDs. LEDs are of no use whatsoever in growing cannabis. Most ultrasonic foggers have a tendency to accumulate nutrient salts on the vibrating piezoelectric diaphragm. This will cause them to...

Stoney will surely be looking into that oh-so-clever idea one day soon. In the meantime, save the baby food for your baby. Your cannabis plants won't want much to do with it. Cannabis plants will produce 3 to 5 bladed fan leaves when they're very tiny seedlings. When they get larger, they...

If you have 35% H2O2, use it at 1.7ml/L every 3-4 days. The once-off shock treatment should be at 17ml/L for 35%.

pH jumping up like that can be indicative of a pathogen problem in the system (pythium, fusarium). Us 50% grade H2O2* @ 1ml/L in the nutes every 3-4 days. Since it appears you have a significant infection in the system at the moment, do a one time treatment at 10ml/L then return to treating at...

Plants in clay pellets can tolerate frequent watering. However, if you start clones in rockwool cubes, make sure the RW cube does not get flooded/dripped. In drip systems, use a drip ring to assure that you're wetting the pellets but not the RW cube. Buy them assembled or make your own from a...

thanks. :) perfect. :) yep, that's the way. :) 5.0 is a bit too low. You'll lock out just about everything but iron & manganese at 5.0. Cannabis is an astonishingly fast growing plant particularly in optimal conditions. I can see the correlation with a pet! Upside is it won't pee on...

yeppers, it's overwatering. Judge the watering by the weight of the pots. When about half to 2/3 of the water weight is gone, it's time to water again, but not before. Might be every other day or even less. I don't do soil so I can't tell you what the pH should be. You're also on your own with...

Will if I can but I don't have much time to put into pot boards at the moment. I simply don't have time to get caught up in troubleshooting grows. Quite a lot of what you need to know has already been covered in my cloning, '2 weeks' or other sticky threads. Yep, thanks for covering the tank...

In the case of running this sort of thing with water from a dehumidifier, it depends upon how long the plants are asked to cope with 7.0 water. Yes, diluting the 5.8 solution in the rez with 7.0 water from the dehumidifier will cause the rez pH to jump up. Just how far and how fast depends on...

I use flood systems, but this arrangement will work with any watering system which employs a nute tank: https://www.rollitup.org/hydroponics-aeroponics/6638-vacation-watering-system-flood-hydro.html Ignore the dehumidifier (and my very old, kindergarten art...). My op needs a dehumidifier...

Thanks for the thanks, DD. :) The writing gig is plodding along, but so is my op. I only get about 2-3 hrs a week that I can plug into writing about growing dope these days, usually about 3-5AM on Sundays (Aus eastern time). Well, I haven't disappeared from RIU...

no wuckin' furries. :) well, thanks, but you'd thank me more if you got stuck into the threads. I wrote about growing dope because I was so frustrated seeing noobs struggle when they just didn't have to. Get A Harvest Every Two Weeks was all about never running out of dope while not actually...

saur, thanks for the thanks. . :) If you've read the cloning & '2 weeks' threads, you'll do fine. :)

Looking good. I'm a little concerned about the leaf purpling, could be hitting the nutes too hard in late flowering. Might drop to 700-800 in wks 6-8.

Go easy on the eskimos. Everywhere I've seen an indigenous population, I've also seen abuse and abandonment of them by the 'conquering' nation. Add unemployment and alcohol to poverty and you get some people with problems, but those have been thrust upon them. Incidentally, it appears as...
