    Weird PPM readings...

    I built individual scrogs on top of the bucket lid with pvc frame that square over the lid then go out wide and up so it's all one contained lid plant/scrog unit. Moving to the side is the typical way, or pull the whole bucket out, and you can swap the whole lid with everything into a new base...

    AirROS by Sage Industries! No more bud rot!

    So like using CO2, you'd need a sealed grow to make use?

    Weird PPM readings...

    the less water you have in there, the sooner the ppm's will drop too. If you have 3 gallons, to take 200ppm from 3 gallons happens a lot faster than if you had 20 gallons the plant was feeding off of. In a 5 gallon bucket in flower with a big root mass you are going to be sucking down nutes...

    Weird PPM readings...

    Have you done a full nute water replacement or are you adding nutes to what's in it? I'd let it feed down for a few days and replenish with fresh mixed clean nutes. Trying to add nutes to existing res, especially with a small bucket, is hard to keep even since you don't know what the plant is...

    How's it been coming along?

    RDWC/DWC build help advice needed

    If you are mixing for individual buckets, 5 gallon blue water jugs work great for mixing nutes and pouring in. Fill em with RO, and it's easy to shake and swirl the whole jug with cap on to mix and then pour in. I would always mix up enough extra to replenish thru the week. It would stay fine...

    DWC Indoor in Tropical Environment

    If your indoor temps are going to hit there you are going to need to think about cooling. Hydroguard certainly helps, some Z7 is good too. 30c water is asking for trouble imho though. If you attempt it, do full water swaps regularly and often and keep good eyes on your res. If you can avoid...

    RO Water RDWC

    My tap water is gross. RO is pretty easy. Got an apex roes-50 or something like that, a permeate pump (no electricity, improves speed and also efficiency so less waste water from the RO) and have it plumbed to a 55gallon water barrel with a teeny float in the top. Hose drain valve and...

    Missing the obvious? Why is a reservoir needed? If no space.

    It's also helpful if they are connected well enough for drain out and water changes since you don't have to try to prop the lids with plants and big roots and try to get all the water out. I have one of the 55 gallon totes for a topoff like above and it'll hold 34 gallons or so. I did put a...

    No matter what I do the ph in my 1 DWC rez is 6.3

    What temps are the rest water at towards end of lights on time? The more I have to adjust ph in the 5gal, the more unstable it gets over days if you have to really fix a swing. Make sure it's cool, and I'd probably do a full water swap to be sure with fresh nuted water. Since your ph has been...

    What Sativa would you grow?

    I'm currently growing a J-1 from Pacific seed bank (only 1 of 10 seeds sprouted/survived, they were 1.5 years old though.) Nobody else has it but them after looking for a very long time. I wonder if it's real too. It is looking a lot like the jack herer's growing next to it, I hope it's truly...

    What Sativa would you grow?

    I'll echo the Jack Herer to the mix another time, it's pretty fantastic in functional effects.

    Best rdwc system

    If you are looking to buy a complete one and you have the money, getting a current culture system will give you a full complete setup that will last. I custom went with a CC epicenter (that bottom drain is handy) and then CC 3" bulkheads into a custom setup with eztotes with CC lids. Built it...

    RDWC - nutrients uptake drops after 4 days

    What ppm scale are you using? That must be 500 scale? Are you starting with RO? Maybe you need to up that calmag, been running 4ml thru late veg into w4f to account for starting water. I had some a swing early on where it seemed like they needed more. I went along with this from CC's site...

    RDWC - nutrients uptake drops after 4 days

    If you stop injecting into the system does it continue to feed the ppm down? Stuff seems better mixed when you start from RO thru the mixing vs adding to the system with already loaded nute mix. When you had it go bad in the top off with nutrients, how did you know it was bad? Did you have...

    RDWC - nutrients uptake drops after 4 days

    Seems to me when the plants eat the ph floats up. I have a bluelab controller that holds that at 5.9. The ph only seems to drop when the water change is due and there is some nute lockout from all their feeding. They continue to just consume but if the ph drops it's time to change water. What...

    RDWC - nutrients uptake drops after 4 days

    What are your ppm's when mixed fresh (and what ppm scale) and what is it dropping to before rising? How's the ph?

    Reverse osmosis filter in loft

    You can plumb a 1/4" line from the RO to anywhere you want I ran one to the top of a 55gallon water barrel and was able to suspend a small float valve inside to control the topoff of it. The barrel is on a raised stand and put a ball valve in the bottom with a hose connector to control...

    Lighting during flower

    Any flexability on the long branches where you could angle the tall colas over more on their side? Late to supercrop but maybe you could time em down. Next time really LST or scrog and try to keep the canopy even.
