Big RDWC, GH trio, changing ratios without dumping the nutes.

I guess I could start a grow diary! i have 4 new seedlings in and 4 coming in post to put in in next few days

2xLSD
2xbruce banner
and when they come 4xgorilla glue no. 4
oh and 1x CBD for my mum who has Parkinsons.

Thanks for the great replies guys, I will one day upgrade to a bigger RO but the damm things are so expensive!, what do you all think of my DIY CO2 gen? I've not had a problem with Pythium etc so far (prob due to the sheer amount of water and good circulation keeping the temps down even when the room is at 30°). I keep on-top of my EC so adding back strength isn't too much of a problem but what concerns me is the transition from 1-1-1 seedling stage to the 3-2-1 veg stage. At this point I think im just going to add back with 3-2-1 and empty just for transition into flower. I will have to get another res like you guys have said and let it fill a couple of days before the change over, I can use the pump in the bottom of the res to pump water back in, just hook a pipe onto it. If was to build another I would spend the extra 70€ on proper bulk head fittings as I had a small leak during the last grow so I have siliconed them into place, they are good now but forever fixed in place lol.

Sorry I completely missed what you were asking! I'd say that increasing the ratio may be OK but because you're transitioning from one ratio to another it's hard to say if things would stay in balance. I hate to be that guy but I'd say full res change. Not saying it wouldn't work but my thoughts are better to be safe than sorry. Good luck buddy!

tbh I know 0 about co2 but did think your fan/filter was a bit odd?

on the floor? In a sealed set up they are just used to circulate and scrub the air. I got the idea from someone else's setup! The CO2 gen is just a portable LPG shower unit hooked up to a CO2 sensor, works a treat!

Thanks bud, ill keep you posted!

Peroxide is a good shout. Not for adding oxygen as the agitation of the water as it moves in and out of the system will provide plenty of oxygen but will keep things clean. The chillers are only really necessary if your res is over 20C. If you run the resoviour outside of the growroom he should be sweet. Watch the EC, PH and temperature and you should be good. You can get disolved oxygen test kits from the pet store if you want to test for oxygen in the water.

I like the idea of having a DO kit!

People use them for aquariums. Maybe give these a try?

This is the one I have, hooks right to the sink. Takes about an hour to fill 5 gallons. Took my tap water from 300 ppm to 0

Please do - and more info on PD would be good - my dad has it but wont smoke etc. He is on oil atm tho after years of me pushing.

I make RSO for mum and then decarb it in the oven and mix it 1-1 roughly with olive oil, I know its not exactly lab tech but it does seem to help with her tremors! I bought a Buchner filter (it makes filtering so much quicker) with a small manual vacuum pump. I live in France and we still have a strict policy on the old , I try and get one of hers in with every grow i do, Ive tried slightly higher THC but she had a bad time. (shes a real lightweight haha smoked like twice in her life)

Thanks bro, never thought of it before, always thought they would be really expensive, I would like to conduct some experiments on how DO relates to water temp.
