Any advice. Right now it's just 5.8 ph'd water with 1ml per gal of silica. Tinfoil is only for light blockage.

I've been reading about a few deficiencies that can have burnt tips as a symptom and wondering what you believe this might be. Blackberry fire, 13 days from rockwool clone transplant. Undercurrent system Ph 5.75 PPM 380 75-77 temps Humidity 75 but down to 50 when exhaust kicks on for about 10...

With the new UC system I built I realized I don't have enough room for my ac in there. It's a 10x5x8 grow tent and unfortunately I eyed the space for everything a little off. The weather was dropping in the bay but ofcourse we are getting a good hit of Indian summer. For the time being I'm just...

I tried to search around because I think I may have asked this but can't remember. This is not specific to my current grow but something from my last full grow. I grow in a diy rdwc/undercurrent system. In late veg I got all the way up 2.4ec and it was dropping pretty fast. I started at 1.2 and...

I grow in rdwc and always get purple stems on my fresh clones for a couple weeks. After the first couple weeks everything comes in green but not till then. This last batch I put an extra one in coco and it has the same exact thing. The coco plant is outdoors in the bay area and the rdwc is...

I'm preparing my hydroton and ph'd the water to 5.8. When I just went and checked on them the ph had risen to almost 8. That's in a 24 hour period My question is should I be readjusting the ph back down to 5.8 until it balances or is the internal ph of the hydroton still at 5.8? Sorry if...

I found this interesting side by side comparison, yes with lettuce but, of plant growth and taste between white LEDs and blurple LEDs. We've always been told that the blurples are shit compared to white LEDs or HIDs but usually it's just anecdotal evidence. I just thought it was very...

This move is called the upward and out sun pose.

I have 4 adjustable Samsung f564b, similar to quantum boards, fixtures I built and need to find a good setting from transplant of clones through veg. I just spent an hour online trying to find data that goes against my understanding yet every site I visited said the same thing. That t5's which...

I quit my grow finally after wasting a month of energy and endless attempts to fix the issue. I just took my net pots apart which were 3 inch with hydroton surrounding the rockwool. The water level was about an inch below the bottom of the net pot. I had absolutely no bubbling in the totes...

I recently switched from using air pumps for a number of reasons and switched to fountains and waterfalls. The only thing is I think there is more to be added from air pumps than just DO. It seems one of their important roles is misting the roots above the waterline or getting roots to drop...

The below pic is of an extra clone I was given with my girls now in my undercurrent system. I just went ahead and used the mix from all the clones I transplanted to repot this girl. Should i be using the same nutrient setup and ph as i do with my undercurrent? The redwood pieces are just...

Title says it all! Just seems like an obvious misplacement of a sub-section but ofcourse I'm wrong and someone will inform me why. Unless people search for it purposefully I bet most end up missing it, I did!

I know there is endless amounts of information out there on the subject but I need a little better direction. The first, 2 grows ago, grow I did was a scrog and it went just ok. The biggest problems I ran into was, over crowding before the net was close to full and lots of foliage damage and...

For anyone whom has ever attempted running an active system in hydro what were the issues you ran into with it and how did you overcome or prepare for these issues. I made some tea with Bu's Biodynamic Compost tea and molasses. I also made some bio ball canisters out of 3" net cups and neoprene...

Through all the reading I've done I had not once seen ultrasound mentioned as treatment for cannabis pests. I will agree that this test was not done with cannabis but with fruit but the results should carry over. I've also been reading about people using them to get rid of white flies as well...

On to my 3rd grow with my new home built undercurrent system. Just transplanted from dirt to net cup with collar and no substrate. Next is an 8x2 scrog for each row of the grow. Running Masterblend, Calcium Nitrate and Epsom Salt @ 10/10/5. Temp 90 Humidity 80 PPM 360 PH 6.0 Hope all...

I understand that nothing can make up for an incomplete growing environment but let's look past that. I'm looking for a strain that is good for pain and stress but perhaps not prone to hunger swings. I already have an issue keeping weight off so I need no help there. I'd also like something...

I have what is basically a homemade quantum board, just to make it easy, putting out 1500w. I'm wondering would it be worth the effort to grow taller plants and hang multiple cfl's below the canopy to decrease popcorn? Or would it not be worth the extra electricity it would take in the end...

I've always received very strange looks and comments based on my cannabis use. I'm what you might call a pothead or heavy user and was wondering if I'm more the norm among growers or still on the fringes of having an amazing addiction which I love!? I regularly vape between 1.5 ounces to 2...
