Hi Everyone, I am new here so firstly I would like to say hi to everyone and that I look forward to what I hope will be a long journey here on this forum. I have never grown before and I am currently prepping for my first, I will be germinating this weekend. I have just been calibrating my new pH & EC readers (both are Essentials) and getting base readings for our water. Here's where things are getting a little strange, we have an undersink reverse osmosis filter (we've had this for some time now as I don't want the tap water for obvious reasons, I have however replaced all the filters a few days ago to get the best of the best for my girls-to-be) and I know manufacturer (iSpring Water Systems) specification is that water pH should come out at 7.4, it came out at 8 which is fine for myself and will just have to use a lot of down, but the EC reading has come out at 0.8, which even as a virgin grower I know is waaaay higher than the majorities. I know that during filtration some ionised minerals are added (calcium, magnesium, sodium & potassium), but this has thrown me off completely as I now have no idea where I'm at with nutrients. My plan was to start the seedlings off with around 0.5-0.6 EC (assuming a base of 0.2) as I am growing in coco, so 0.8 is already higher than that without any nutes added. Should I just treat this as my base? Should I use normal tap water? I really am lost and have no idea how to even find the answer. Any help or general beginners advice would be hugely appreciated. I'm so excited to be joining this wonderful community and can't wait to progress, happy growing!
Evening all, I’ve pretty much blocked my second carbon filter because of running tap water through my humidifier. I was getting 100ltrs of RO at a time from the aquarium shop but became a pain in the arse but I think it’s really time I got myself an RO filter. I’ve only got a little 1.2 tent with a 315 cmh and 600 hps in, I usually do from 4-8 plants and have to fill up my 8l humidifier every day in early veg... So never going to be using loads of water. I figured if I’m getting a filter I may as well use it for water the plants as well. I’ve been looking at 3 different RO filters In my local grow shop, ranging between £217-308. First is a Power grow 500, then a Maxquarium at £242 and finally the Max grow 1000. Which one do you think you be suitable for my needs? Having never used one before are the 2 chamber filters much slower than the 3 chamber? Also looked at the 5 stage household jobbies for about £100, are these as good? And would it be that difficult to fit? They’re a damn site cheaper than the ones in the hydro shop! Any help advice would be much appreciated
Hello everyone. I have been thinking of converting to RO water as my tap water has background ec of 0.8-0.9. So i was talking to somebody about using RO water to water my plants, he then told me RO water is really unstable and i will ph it when i water my plants but after a couple of hours the ph will crash to something like 3.0 does any body have any experience using RO water? all advice is welcome!
