    Default RDWC how much PK to add

    Hello all my first grow with RDWC system. So far my plants look great 3 weeks into flower 360 litre system 8 plants. I have another 8 plant system for veg.

    I needed to veg the plants for a week longer in the flower room so started them on grow nutrients then just topped up with bloom nutes around 1 week into flower and have continued to do so, around 20 litres a day.

    I am in the zero change out camp apart from flush (they had a fresh batch when they changed rooms from veg to flower).

    My question is how do I add the additives such as PK and Shogun Dragon Force and the bloom booster?
    Do I use enough to saturate the full system ie: 360 litres worth of PK in one go then just add the required amount to further top ups?
    Totally new to RDWC so This may be a stupid question.
    Many thanks

    Interested to see some of the replies you get Mate, I run rdwc and I’m currently using Shogun nutrients. I don’t have much experience but the pk I noticed is very strong. Good luck anyway mate, would love to see some pics of your set up and grow

    Mine's a home made system weed junkie. Seems to be working well. Cocked up my first attempt by feeding to high, burning the roots and letting root rot invade!! I was running sterile then but have switched to hydroguard.

    If I get time I will post some pics tomorrow.

    I grow in outbuilding North UK and have to put aquatic heaters in there to keep the temps up tp 18c. May be a different story in the summer. If you go with non sterile I think you have a better chance with higher temps.

    DIY is not difficult apart from getting the pipes into the uniseals. Still works out quite expensive though. I use the micro bubble airstones which are expensive but worth every penny.

    With Remo Nutrients i added them in equal parts . Some like 2 parts of it to the base . But found in dwc they burned .

    Started at 1/2 and see once the pistils start showing round 2-3 weeks and up it very slowly . Ive had cuts of same mother respond differently .
