I’m getting ready to swap out my HLG-550 for a new HLG-600 in my 4x4 . I’ve always ran my HLG-550 between 20-24” above canopy during flower, but I see on the website it says to run the light 28-36” above canopy, which seems a little high to me, even with the extra 100 watts. Just curious to see...

Anyone here use Breeders Direct before? I like that they use cashapp and I feel like I’ve heard they’re legit before. also, does anyone have a coupon code for them?

Came across these bags called "grove bags" that as far as I can tell, are basically bags with boveda-esque technology built into the liners of the bags. Has anyone here used them at all, or know anyone who used them for curing? not looking for a debate on whether its better to stick to the old...

has anyone here ordered organic inputs from kelp4less? i like that they’ve got just about everything I need for my teas and they offer free shipping, just want to make sure that I’m purchasing quality inputs, specifically their bat guano. or If someone else has somewhere better that I can order...

As I’m wrapping up two of my tents, I’m starting to think on how I can improve this next run. In my main tent, I ran 70/30 coco perlite (under quantum boards) and I feel my finished product will be limited a bit due to needing to use extra calmag with my RO water, and having to reduce my base &...

After watching one of this weeks episodes of DGC, I learned the difference between potassium silica & silicic acids, in terms of bio-availability to the plants. Was very useful info, and after digging deeper, i discovered that the silica that is in Megacrop, is actually silicon dioxide which...

Been putting some thoughts into Octopots, there are a couple guys using them in local facebook grow groups that seem to be getting good results. Who all has grown with octopots on here, and what did you think?

Has anyone here ever used GLN’s Sea-K? I’ve been using Rhizotonic anytime I transplant, and its worked wonders for me, plants don’t even skip a beat. However, Rhizotonic is a little hard on the ol bank account, so i’ve been looking for something that will give comparable results. I’ve got a...

Looks like Chuckers Paradise is down, greeted with splash page that says “forum is for sale” and nothing loads. wonder what the deal there is. bit of a bummer, RIU and chuckers paradise are the only online communities I still enjoy. Reddit is full of “know-it-alls” who know nothing, too much...

This is the first time I’ve ever measured the EC/PPM of just Calimagic. Everything I’ve seen online says that 5ml comes out to roughly 500ppm, however both of my TDS meters are showing that it takes 3ml to get my RO water to ~150ppm (.3 EC). Are my TDS meters both out of calibration or is this...

Thinking of trying out a bag of MC in one of my tents. I feed DTW in 70/30 coco/perlite, underneath HLG Quantum Boards. I use RO water. From searching the forums, it seems like a little bit of calmag is still needed with RO & coco, despite the extra cal that MC has. I’ve got a giant bottle of...

Hello all, I grow indoors, in tents, using a mixture of coco and perlite. I feed drain to waste, to 20 percent runoff. I currently use a generic 2 gal watering can I got off of amazon, that has a plastic shower head end spout. It works great after the first topping, but up until then, I have to...

Hello all! I’ve been using QBs for the better part of a couple years, occasionally upgrading to the newest diodes. I’ve always been super conservative with light heights, as I am with just about anything related to growing cannabis, to avoid any king of light burn. What I usually do, is dim...

Where I live, the laws against growing have always been insane, and then we passed medical marijuana and everyone’s a master grower. something I’ve been seeing here recently, is people intentionally keeping their lights too close to the plants and letting the tips bleach. not knowing it was...

So I would consider myself intermediate in terms of knowledge pertaining to the cultivation of cannabis, maybe a little bit more advanced when it comes to LED technology. However, the only time I have ever used fluorescent lighting for anything other than light, is when I used to breed bearded...

So up until about a year and a half ago, there was no way to legally grow in my state and the punishment if caught was typically 10-15 years, so due to paranoia, I have never kept mother plants myself. Now, with two medical patients in my household, we can grow a total of 24 plants. We’ve got...

Here lately, I’ve been Doing the beginning legwork for two “passion projects“, finding a good source of seeds for legit cuts of NL and of skunk as well (want to find something that throws RKS phenos). This weekend, I’ve been doing a lot of thought for strains I have really enjoyed in the past...

Anybody know of any breeders running Black Friday specials? I read that Greenpoint is running a sale but other than that, I haven’t heard of anyone else.

hello RIU! So, over the years, I’ve been through a bit of an evolution of pots for my pot. Started out with DIY buckets in the backyard, and have been using fabric pots for some time now. Here lately, I’ve been doing a lot of research on little things I can do to help get just a bit more from...

Hello all, So I’ve been revamping my main tent, a gorilla grow 4x4. I recently ordered a new 480w QB using the LM301H & Cree xpe2 660nm diodes and putting my old lm301b board in another tent. I have been planning on getting two of the far-red initiator pucks from rapidled And running them 2...
