Could do with a pointer to the tech I should be looking at, Things keep changing with LEDs, COBs etc. Currently I use a 400w MH to veg in a 4x4, and a 600w hps, OR, 2 x 275w (at the wall) Mars Hydro Blurples (the long ones, 1 x 3 "grid" of LEDs - old school). School's out on the flowering HPS...

I've got a bubble cloner than uses small net pots, 2". WHen transferred to my RDWC system that uses 5" netpots. On this (1st) occasion I snipped the small netpots around the base to allow the roots to be unrestricted, and then put them in the 5" pots for the RDWC system. As the "seedlings" had...

Just about to run my 1st RDWC setup. I'm usually an NFT guy. One big concern is flooding. I hear often of roots blocking recirc pipes and then the master pot, or one of the slaves overflows. This can't happen. Are there cheap ultrasonic depth sensor kits out there for all my pots ? or am I...

Been growing NFT for many years. 1st time I've experienced this. Was doing housekeeping and noticed lots of dry deal leaves at the bottom of the canopy - not that unusual, then started noticing leaves that are wilted and black tipped and soft, all lower in the canopy. Then noticed a couple of...

I've been growing NFT for eons. I know it. I know it well. I can run a 40 litre GT424 all day long in a 4x4 tent - I know how to keep the PH in control, and the Nutes. I'm well versed in it and never have root problems. Temps are UK temps and therfore easy to keep the tank/nutes at a reasonable...

For anyone seaching a specific 120 mm fan type for reducing fan noise: I replaced the stock fans in my Mars reflectors (3 fans in each, 9 fans in total) with these from Amazon: ARCTIC P12 - 120 mm Case Fan, Pressure-optimised, quiet motor, Computer, Fan Speed: 1800 RPM - Black, Black Rated at...

My primary room in an outbuilding. Had an aweful last crop for reasons that I put down to cold. Fairly sure of this. Only other change was switch from a GT424 tank to a GT100 tank. Rectangular 42 litres to square 100 litres. Now heating it, and running a near identical room indoors. Both rooms...

The main reason I grow is to enjoy old school highs. I smoked UK available stuff for ages - cheese, super skunk etc, then one day realised I was just battered, and not actually enjoying it. It also made me anxious. So now I have Master Kush, Hindu Kush, Purple Bud, Mandala #1, Blueberry. All of...

My girls are healthy, and the right height for switch to flowering. However, I have two corners to fill yet, by training them along the scrog netting. (tank is diagonal for access reasons) Usually - I wait a few days and then train the tops that have gone too high. Sometimes gently, sometimes...

Hi - I've happily grown in NFT for ages. This time I've tried SOG as opposed the the usual SCROG. I time lapse my grows so have a photo from every day from every grow. Great for diagnostics. This one is odd. In my SOG, I flipped to flowering when the plants were very small - i.e. around 8"...
