So I've been doing the method advised by DJM and a few other seasoned pros using coco. Which is During veg, water and allow the medium to dry a bit (Not bone dry as to harm the roots) Then during bloom to smash it with multiple small feeds which has worked a treat. I've managed 650ish grams/m2...

Hi guys, I run high humidity, but mainly because i can't help it (the high RH is caused by the plants). I'd like to make one thing clear, some of the VPD optimal zones with temperatures 78-89 show best humidity in the 75%-85% area. Reference...

Hi, So I've had a look at this product at this store, it just sounded too good to be true. https://hydro4u.com.au/product/dna-grrrow-60-ml/ Claims to reduce veg by 1 week by stretching out the entire plant. Has anyone used or know what could be in this or of any other alternatives there might be ?

Hi. Just switched to RO after using about 200-290ppm tap water the last decade. The hydro store claimed massive yield increases. Ok from using tap water my past grows, I've noticed the ec in is always building up so I'd have to go 1/2 strength nutes regularly. However for the past entire week...

Hi. I'm planning to use 4 x hlg 600h 48ab drivers and was wondering if the sonoff 4ch would be adequate. I understand that those heavy duty times using contactors are essential for magnetic ballasts. However the 600h has an inrush current of 70a. The sonoff devices use relays rated at 10a for...

Hi, Just wondering if anyone has done this and with any success. A bucket with 1 hose on top (drain hose) with a feed ring on the very bottom attached to a bubbler which also pumps out the nutrient to the top. The only difference i see is that the drain hose is near the top compared to the...

Hi guys. I'm doing a coco drain to waste with one pump feeding 16 feed rings. Anyone have tips on how to get a perfectly even feed? They have taps and its almost impossible, because u adjust one tap and the other gets more etc. Then mid flower some of my rings are clogged with this brown gooey...

Hi. Thought I'd give my 2c. Got this idea from the 4lbs per 4x4 thread. Let's face it. Most growers aren't limited by the power available, but the grow space available. Another thing most growers chase is yield. LED tech has become efficient enough that the lmc561 and 301 make a difference to...

Hi all. In the interest of saving more power ( my bill just came and its 3.7k). Is there any experience in here when it's ok to dim the lights without any yield loss? I mean this is a major advantage for us LED users to be able to dim up to 1/10th. From my own experience, I usually dim the LEDs...

Hi ! Just trying to dial my feeding schedule. I'm using airpots atm Feeding 3 times during lights on. They're 45 L airpots and each feed i give them about 3-4 Litres. Just want to know what works for people and if they've seen improvements changing from one to another. Thanks.

Hi ! Just wondering where everyone is locating their temp/humidity sensor. Im getting massive differences in readings 62% near ceiling, 67% a foot above the floor and about 80% inside the leaf canopy. Now, I have perfect airflow and movement so i dont think i'll have any problems. Just a heads...

Hi. Because LED are so damn bright, don't put out much heat etc, I think it's time for someone to try a few under the canopy facing up. I've noticed they are bright enough that you can see through the first leaves it hits. Wonder if there is any photosynthesis efficiency data from the light...

Hi, Thought I'd share a grow with everyone here since I've been on here and learned so much. There's going to be a few haters with using PGR's but i only grow what they want me to. Here are some pointers to know. About the room Size is 12ft by 16ft Room is split into 2, one smaller room to...

Hi, Just wondering what is the hottest high PAR light out there that is better than your standard HPS/MH. Since starting my LED grow, I've noticed that my plant growth rate declined because it was just too cold ! (16c inside grow room, ambient outside is about 14-16.) I've since turned on 6 x...

Hi Had hermies in my previous grow, here is what the root system looks like, and on the larger buds there were lots of single leaves and not much trichomes at the end. Would this be considered rootbound!?? root rot?? etc. Also, in my new room, i have a cloned afghan kush from a female plant...
