Is it common for the first leaves of a healthy seedling (not the cotyledons, but the first jagged leaves that appear) to yellow before there are 5 healthy leaf sets? Just wondering. Someone told me that it is, but I do not remember having had that happen when growing in soil.

Not growing yet, but curious. Wondering, when I have plants in flowering stage, can I alternate between hps and direct sunlight outdoors? Every other day, my plants spend their 12 hours outside let's say. Is this likely to stress the plants? Also, what if instead I were to alternate hps...

This is something I've been wondering about. I read that THC dilates the blood vessels in the brain. I read that it is effective at slowing down amyloid plaque formations and tangles in the brains of Alzheimer's victims. Can't help but wonder if these things are due to THC allowing the body...

Metal halide lights. The following example isn't really cheap, but I've seen the same lights as these sold MUCH cheaper on ebay. Of course, anyone knows that it is a big risk, buying used lights such as these. I'm really just curious to see if anyone has bought and used with good success...

The hood on this MH/HPS light is huge. 3'Lx1.5W. All 4 sides are bent to 45-60 degrees. Metal has a mirror-like finish. Would this hood be too large for the area that a 400 watt grow light is able to serve? (Can't post a pic. Sorry.)

Hi there. I see that many folks with cfls are using reflective mylar with them. Well, let's say I have a room that is 10'L x 7'W x 7'H, and a 400 watt hps lamp. (mh conversion bulb used for veg, then switch to hps bulb for flowering.) Would it be better for the plants to cover the walls with...

I have a quartz space heater. Well, you know the light timers that you plug your lights into, then you plug the timer into the wall? I'm wondering if there is a thermostat like that that I can plug my heater into. Anybody know?

Purely hypothetical, so please don't bite my head off, m'kay? ;) Curious about this. 10 week harvest, 21 days veg, 49 days flowering. I know that I should shoot for a minimum of 30 days veg, but let's say 21 days veg for this question. Okay. Lets say I have a 400 watt setup (ballast...

In 36 years, I've never been able to get high from weed. It even made me sick the few times I tried smoking it in earnest. I got my Mom vaporizing for health reasons, but I normally don't partake. Well, the other day, I took like 5 hits off her vape. Hurts my chest and makes me cough for 2...

Hi. This question may have been asked milliions of times, and it may even be in some faq somewhere. Unfortunately, my internet search capabilities seem to suck, so I am unable to find the info here. I know how to wire a series of light sockets in parallel. Due to an electronics class 4...

Is this a good price? 150 watt HPS bulbs

If this hasn't been determined scientifically, then let the more experienced among you toss out some guesses. Pretty please?

Then take your winnings, and buy better bud: Jackpot? hehe :fire:

I tried to do a search, just once mind you, and got this message: This forum requires that you wait 20 seconds between searches. Please try again in 9577 seconds. I waited for 40 seconds, and got a similar message. How long is 9577 seconds, anyway? :sad:

Looking to buy a vaporizer for a relative. I'm hoping to get some reviews of the cheaper vaporizers out there. Looking at the Blue Meanie, the Vapor Box, and the Vapir Air One 5.0 . Have any of you used any of these, or similarly priced models? If so, please weigh in. Your experience will...

Hi there. :) East Texan here. I'm new to the scene, and looking to learn. Medicinal purposes (sick relatives). This site looks to be a fountain of educational material. How happy for me, and any who need it. :) --Fran
