I had to take my Sunsystem 315 LEC lights apart to re-mount them. They have built in ballasts. They are located behind the cover of the "Heavy" side. I found that they have a (ok not super cheap) and easily available ballast! As easy to change as a fluorescent ballast if it goes bad. Simple...

So here goes running some auto's in a home built RDWC. Planning on topping them when the time comes. Soaked the seeds for a day in a light H202 solution. Used rockwool cubes, soaked them in a 5.7 250ppm nutrient solution. Using chlorine @ around 3-5ppm to keep everything nice. Put them under the...

Hey guys, a quick question. In regards to DWC/RDWC So if you start with a certain amount of PH 7 water and use some acid to drop it to 5.8, would evaporation over several days cause a slight PH drift down? The evaporating would effectively concentrate the acid since there is a less amount of...

Here we go again. System took a weekend to get back up and running. I had folded up the tent and put everything into totes last year so I could use my garage for other things.

So, in need of a storage container and out of anything, I threw my freshly trimmed larf/smaller buds into brown paper bags. I kept them elevated off the ground. What I found is that they dried much more slowly than hanging. This is important if you live in a DRY climate. My RH is normally 35% or...

Anyone ever tried running something like this inline and seeing how it much it drops the PPM...

So harvest week is upon me. I am going to cut this weekend. No flushing, I am just tapering down the nutrients based on what I am seeing the PPMs do. The plants have wanted around 350 ppm at the moment and its going down every day. I heard that you should keep you plants in the dark the night...

Hey guys. I will start by saying I have never grown anything before, and I pretty much have gotten to this point sticking to a lightened feedchart another guy named Airwalker posted up on here, that can be found on Grow Weed Easy. Since I am actually looking at harvesting I wanted to get any...

Hey all. I am getting brown streaks on my middle and upper leaves starting about a week ago. I am getting brown tips too, but I dont think I am overfeeding. Running a low ppm @ 550-650? My PPM will drop for a day or two and then will rise the rest of the week. PH does the opposite. I don't let...

So this is more to help someone that may be having similar problems than needing help. I am a new grower and I am running my first grow in a homemade rdwc. After about 3 weeks into flower I started having curled leaves and spots show up. After a res change, PPM would drop for a few days and my...

Hey all. My first grow of anything, ever. I have gotten the hang of growing pretty well, considering this is a home built system. Somehow I have fumbled my way to this point and would appreciate any advice. Just a couple of spots here and there but nothing I am/should be concerned with, correct...

Hey all. I am running an 4 site RDWC holding about 19 gallons of water. First grow, just built the system. Here lately my water has been going down and so have my PPMs. I have a chiller and using bennies so I am trying to go two weeks between changes. My addback method: I started at 400ppm...

Hello all. If anyone can clarify, agree or disagree to these statements I would appreciate it! I am trying to figure out NPK ratio's Basically I added up what was on my bottles which is what I am adding to my res. If I added all these in equal amounts say, 2ml of each per gallon I would end...

Does any of this look familiar to you all? I mixed up a hot batch of nutes last week, and the next day I saw brown tips so I lowered the PPM and they went away. I also have a 315 LEC about 20-24 inches above the plants. PH is 5.8 and pretty much stays there GH Trio Nutes 330-350ppm Also my tap...

Hey guys. I have been having a problem with my og kush for about a week now. The other two plants in the rdwc system are mazari, doing great. I know strains have different needs but I am unsure what it is telling me. I will let the pics do the talking. PH- 5.8 PPM 360-400. Any more and it throws...

Hello. I have a couple Mama Mia's that are about 22 days or so from seed in a rdwc. I have been feeding them around 150ppm for a week and they seem to be growing well. My base water is 150ppm for a total of 300ppm. My nutrients have stayed at 300ppm steady all week. PH has stayed at 5.7-5.9 all...

Hey all. I will keep it short. I decided I wanted to grow because my wife and I smoke a bit. With her approval I bought all the stuff I needed. Out of pure luck I scored TWO 315 LEC SunSystem units with the bluish bulbs for under 200. I got the rest of the stuff I needed from Amazon. I have not...
