I have a DWC setup in a 2X2.5 tent under a 200W MH. Will change to 400W HPS for flower. My roots are turning brown from the res being too hot. I ordered hydroguard and will do a nutrient change. Thinking of setting the PPM at 400. Thoughts?

I am trying to get my nutrient solution dialed in. My roots are browning, so I order some hydroguard and will do a res change today. I'm thinking of setting it at 400PPM. Any thoughts? Please feel free to give input on anything else you may notice. New grower.

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...

I am purchasing a clone to start a small DWC grow in a 2x2.5ft grow tent. I understand that a clone does not need strong light until it develops roots. The link below shows some lights I already have, but each is 12w rather than 15w. Would one or two of these be enough for my clone for the first...

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...

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...

I have been smoking almost daily for 5 years; multiple times a day, so clearly I have symptoms when I try to take a break. I am currently on day 4 of not smoking anything and this is my second time taking a break. When researching online I read there are two ways to stop: either cold turkey or...

I'm buying a clone to start a DWC grow. In my experience when you first transplant a clone done leaves die and new ones are formed due to the shock. How long should I give the plant to recover before I start training the plant?

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...

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 to...

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...

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...

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...

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...

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...

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?

Setup: 9x5 tent, 2 x 1000w lights, 6-site RDWC, 740 CFM with carbon filter and silencer. I am also running a chiller. Problem: Room can get to high 80's low 90's and I am trying to figure out the best way to cool it. I can: 1) Get an AC 2) Get an air cooled hood or a cool tube (Don't know...

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 hell of a ride so far and I haven’t even started growing yet. I was expecting to have everything ready to go a month ago, but a combination of unanticipated obstacles as well as procrastination due to fear of ruining something have kept me...

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...
