OK...here's an easy one. It strikes me that the stuff that accumulates on scissors, snippers and fingers during the manicure is dynamite. Any creative, efficient and effective methods for getting the most material. Just scrape and hope to recover as much as possible? Or do any of you experts...

Yep...I just want to do a quick sampling of some growing concerns. What's the recommendation? Microwave? If so, suggested use? Any other tried and trued down and dirtied methods? Thanks!

I have a 14 hole tray that sits on top of a DWC reservoir. Not all of the holes are occupied. If I want to use black/white poly to cover the vacant holes, I'm thinking I would want to have the white side up to reflect the light from the bottom. Anything off in this supposition? Thanks! (See...

OK...I have a PL Midi Reflector with a 400 watt bulb. Here's a picture: P.L. Midi Reflector w/400W MH "Sunlight Supply" Ballast - eBay (item 270295361453 end time Nov-09-08 11:54:51 PST) My question is the placement. I have a 14 hole tray that fits on top of two 2X3 reservoirs. Currently, the...

Typically, how long does it take for the first flowers to start showing up after 12/12 initiated? I should add that the plants, though well rooted (for the most part) were not sexually mature. Also, would one expect to see male flowers before female flowers? Thanks!!

Maybe this should be in Noobie Central...here goes: I have a fourteen hole tray with netpots suspended over a res. The plants are in hydroton and Rapid Rooter plugs. While some of the roots have descended into the nutes, some haven't. If I want to water them, should I water the Rapid Rooter...

How do you know when an HPS bulb is going. Do they start flickering? Give up the ghost suddenly? Or do they start fading imperceptibly? Just for general information sake. This is it's third grow...a 400watter. I got a spare just in case. Just want to make sure that if I'm seeing a light...

I live in a city and use urban tap water for my hydro system. Is there any reason to believe that there would be a Cal/Mag deficiency in regular urban tap water or is that encountered more in RO or distilled water? I'm thinking that my plants sudden display of difficulties might be this or...

My system consists of a 14 hole tray sitting on top of two reservoirs that hold, in total, about 25 gallons. The nutes are circulated continuously via a pump located in the bottom reservoir. The roots are always in solution. My question is whether the amount of solution the pump is pushing per...

OK...I know this is one of the perennial questions, but here goes...I have a 400W HPS in a PL Midi reflector. Not air-cooled, other than a fan that blows in the space in between the light in the plant tops. At this point, the light is probably about 14" from the tops...using the hand test...

Is there any reason to walk down the 18/6 hours of light to 12/12 over a few days approximating the natural cycle? Or is the quick cut to 12/12 just fine? Thanks for your thoughts/experiences.

I have some seedlings in rapid rooters. They are about 11 days old and showing strong root development. They just went under 400 watt light yesterday and seem to be doing well. The light is about 2 feet above them. Are they ready to go into the res? If so, should I run water or weak nutes...

No, not my age. I'm old enough!! I do, however, have some bottles of pH Up and Down and 4.0/7.0 solution from about 5 years ago. Does ANYONE have any sense as to whether these types of chemicals get old and degrade and become unviable/unstable, etc? I'd hate to throw 'em away but I don't...

Has anyone used both? If so, what are your thoughts in terms of a comparison? I have a Can 33, which I haven't used yet, but it takes up an awful lot of room at the top of my cabinet. I'm not inclined to switch it until I see how well it functions...BUT odor is a real issue and I'm interested in...

Here's an easy one...I have been working in my little tiny cabinet and doing some retrofitting. I want to clean the bulb that is in the reflector in case dirt or oil (from hair and/or fingers) inadvertently got on the bulb. Should I use a cleaning agent like windex (or something else) or...

Here goes... 1. I have a Can 33 carbon scrubber. I'm just installing. I notice that it has plastic wrap covering the fabric. I'm presuming that the plastic wrap should be removed. Am I correct? (Ridiculous question but -hey - this is the noobie forum, yes?) 2. I have some seedlings that...

Quick noobie questions... I'm thinking of using a Can Filter 33. The bottom appears to be solid metal, leading me to believe that the air is sucked through the sides. Am I right, or do I have to do anything to the bottom of the filter to "activate" it? Are two bungee cords sufficiently...

I'm thinking about a new grow after about four years of inaction. I'm seriously contemplating ripping down the mylar that was used previously...It looks dirty and quite possibly moldy(?) and the prospect of cleaning it just does not appeal to me. So, I thought I'd give black/white poly a try...

From Flying Dutchman. Has anybody had any experience with either of these? I'm thinking of giving one or the other a go. If so, I have to move quick...so don't be shy!! Thanks!
