    Brown Roots

    I purchased a clone that I put into a DWC setup in a 2X2.5ft grow tent. It's been almost 2 weeks and the leaves are a little yellow, but more importantly the roots are turning brown. What could be causing this and what could I do to prevent this from getting worse? EDIT: I just noticed a...

    Making CBD pills

    I am going to make CBD pills and I had a question about decarboxylating. I have done it in the passed by eyeing it, but was curious if there was a better way to got optimal results. Everything I read online tells me to decarb at high temperatures for a long period of time, but I only do about a...

    Bud production

    I have grown in the past, but have very little experience. I am going to do a DWC grow in a 2x2.5ft grow tent. I have a 400w light and will turn it down to 50% so that I don't have to buy another light. If I am using 200w of light in a small space how much bud can I expect? I know this is a...

    PH Pen Calibration

    I have a the Oakton EcoTestr Ph2 pen and I haven't used it in years. The calibration is off and I have 4.0 and 7.0 calibration solution. When I put it in the 4.0 solution and hit CAL it reads 7.0. When I put it in the 7.0 solution it reads 10.0. How do I get it to calibrate correctly if it is...

    Help planning a large RDWC basement grow

    I have a basement and I wanted to calculate if it would be worth an investment to do a large grow. If I did, what would an ideal setup look like? I have 6' of height to work with, so I assume 1000w lights are out of the question because it could burn the plants when they got too big. Rather...

    LED light output

    I was looking at the Platinum LED 150w. They say it replaces a 250w HPS and the average power draw is 50w for veg and 87w for bloom. I thought this was a good thing at first because it's putting out 150w of usable light and using less than 100w of power. My main reason for buying an LED is...

    Marijuana Withdrawal

    I have been smoking for about 5 years and I smoke a lot throughout the day everyday. I have a drug test coming up for a job so I decided to take a break from marijuana. This will be my first break. To be honest part of the reason I am taking a break is to find out if I am dependent on weed. I...

    One grow Three harvests?

    I found this showing that there is a different high with the different stages. Is there anything thing wrong with harvesting some of the plant when the trichomes are half clear, some when they are mostly cloudy, and some when they are cloudy to experience the different effects? I am growing 6...

    50w per square foot?

    I often read that when choosing lighting for a grow room one should aim for a minimum of 50w per square foot. I was curious what the impact is if more or less light is used. If, for example, 40w per square foot is used will the plants grow too slow making it a waste of electricity, or will it...

    Juicing Cannabis

    I've seen a bunch of clips on the juicing of raw cannabis and it's benefits and I was wondering if anyone knew the answers to a few questions. Is there a difference between juicing fan leaves and juicing bud? Does it matter what stage the leaves are in? Early veg vs Veg vs flower? I was...

    Air cooled hoods

    I'm going to use air cooled lights on my next grow and I'd like to know any important info about them from those more experienced. I heard not to have more than 2 connected, is this true? How many cfm do I need for each 600w or 1000w light (depending if I use 2 or 3 lights)? Do I blow the air or...

    Question about air cooled lights

    I have an 8x4 tent and I'd like to get air cooled lights to help keep temps down, but my vents at the top are not centered, so I would have to kind of have the ducting at an angle. Will this cause a significant issue pulling air through at the required cfm or will it work out okay?

    RDWC tubing

    I'm going to be starting a grow with a friend soon and I told him the flow line should be twice as large as the return. He refuses to do it this way because he does not understand the reasoning and would rather have the same diameter all the way around. Why is the flow tubing larger diameter...

    Hello everyone! Welcome to my grow! This has been one **** of a ride so far and I haven’t even started growing yet.

    When to give seedlings light

    I'm going to be growing soon with rapid rooters, so I stuck a few different vegetable seeds in there for practice. I assume because they are all different seeds they are germinating at different rates. Because they are not cannabis I haven't been keeping that close an eye on them even thought I...

    Rapid rooter or nothing

    I recently purchased some rapid rooters because I thought I was sure that was the route I wanted to go because it is the easiest route (I read) and I am new to growing. I was recently playing with germination methods and I tried throwing seeds in a glass of water as well as the paper towel...

    UC RDWC system question

    I had my handyman put together a 6-site rdwc system with 10 gallon totes. When we ran the system for a couple of days it did not seem to me that the water was circulating very well, especially considering I am using a 1000 gph inline pump. The return line was flowing back into the control...

    CBD Capsules

    Hello everyone. I am looking to make CBD capsules for pain and so I was researching how long I would have to decarboxylate the weed. It seems that the purpose for this is to convert the THCa to THC, which causes the psychoactive affect. My questions is does this have any medicinal benefit or...
