Something I've always been curious about but am not sure I am getting good information on is, why am I paying $100 for my Hortilux 400W HPS bulb when I could be buying one of these at like 10-50% of the price... http://www.1000bulbs.com/400-Watt-HPS/

I just realized today that my bulb was extremely dim when it came on.. was fine yesterday, I guess it's life is about over... How much is the dim light or the possibility of it going out going to effect the plants during this light cycle until I can get a new bulb tomorrow? Should I just treat...

Anyone know of, or use moisture sensors to determine when to turn the irrigation pumps on and off? I am trying to determine how i can best leave my soil systems running on their own for a week or two at a time and ensure that things are sufficently dried before the irrigation kicks on again...

I replaced the batteries in and calibrated my pH meter today and realized I may very well have been off by about .5pH for a few weeks... checking runoff today everything seems to be around 6.7 which is what my goal is... it's a soil grow, organic grow and bloom nutes, h202, and epsom salts once...

Ok, the last few days I've been noticing drops of water on the leaves of the plants when the lights come on... I've been researching it, but, no luck... what's the phenomenon called?

ok... about 21 days into this grow... this is a skunk #11 plant... Lights at 8" (air cooled hood), canopy temps 81F, night time temps about 65F... pH is about 6.7... no nutes, just clean water right now... Ocean Forest soil... seeds were germed in peat moss pellets... this symptom only started...

Anyone ever try this stuff? What's the high like?

Anyone ever use a thermistor to control fans and blowers based on how hot the room is? Something like this? http://www.drillspot.com/products/466542/Love_TS2-010_Temperature_Switch Thanks!

Anyone have any recommendations on the best shade of white to paint the room walls? I'm in the US, so any brand should be possible...? Thanks!

Anyone know of an HVAC formula that will help me best determine the diameter exhaust I should have based on the CFMs I'll be pushing out of it? I am sure it's some cylindrical volume thing, but... anyone?

Have a problem with one of my Blueberry plants... it's the second week of flowering, Full dose organic (Earth Juice Bloom) nutes... pH is good, just started drooping terribly, and losing a lot of lower leaves... last flush was about 28 days ago... Any ideas?!

Hey guys and gals... got a few plants here that are about 55 days old, still in veg... Fox Farms Ocean Forest, pH is about 6.9 last time I checked the runoff... getting some yellowing on the lower part of the plant and just a few brown tips... nitrogen def., right? Thanks, Josh

I have an irrigation system with a reservoir (a 10 gal fish tank) where I keep the water/nutes solution... well since I switched to Earth Juice Grow, it has decided to settle on me, mostly behind the pumps... I have a pump to push the water to the plants and a circulation pump to stir the tank...

How far away from the plant tops do you keep your MH and HPS grow lights? I know what I've been doing but am curious what everyone else does and why...

I have been using molassas in the water when feeding my plants... it's gunking up my reservoir... anyone have any ideas for alternatives to molassas? :joint::)

Here's two pics, they are both DP Fem Blueberry... both planted and sprouted on the exact same day... germinated and grown about a week in peat moss and then transplanted to 1 part perlite 2 parts Ocean Forest... you can see one is doing well, very well, and the other, well, not so well (sorry...

This little one broke ground (peat moss) about 10 days ago... It's under 18/6 400W MH light... a few days ago I started to notice some yellowing and very small brown spots on the bigger leaves... it doesn't seem to be spreading, but I'm a little worried... any ideas?

I know it's going to vary from strain to strain... but from everyone's personal experience, how long to I have from when the trics turn cloudy till they are turning amber? I am trying to plan my flush accordingly... getting down to the last few weeks here... :joint::mrgreen: Thanks!

I have been using Tiger Bloom for flowering, is it possible to really burn the plants when using organic nutes?
