Guys, I recently switched to Flood 'n Drain from Dirt. Can anyone give me the proper dilution ratio for 35% H2O2? ml-gl would be awesome! Thanks!!!!!!!:peace:

Apply 35% H2O2 at 1.7ml/litre every 3-4 days.

1 US gallon = 3.78L so 3.78*1.7=6.426ml/US gallon

Make friends with the metric system. It's so much easier to work with ml & litres than oz & gallons due to the decimal base in metric.

I think, I have it figured out. two reservoirs, each with a full capacity of 70gl, Let's say 65gl each. 6.42ml of H2O2 per gallon. 65gl + 65gl = 130gl x 6.42ml = 834.6ml every 3-4 days. I paid 25 bucks for 1gl or 3.78L.From one bottle I can get 4 treatments for both reservoirs, and use the extra 44ml in my aero cloners, and to clean tools. $$6.26 for each of the four treatments. 30 day month, dosing every 4 days = 7.5 Doses each month or $46.88 per month approx.

Did I lose ya?
Sorry I am baked and like math. lOl

no, I'm on board. :) Thanks for the compliment. :)

You may find that buying 50% grade in a big 25L (25kg) 'carboy' jug is cheaper in the long run. Check Goog or ye olde phone booke for local chemical suppliers. Should work out to $5/L if you shop well. 50% is used at 1ml/L.

Kudos on the 25L jugs.....The search begins....
After adding to my reservoir, how long should I wait till flooding the table, or should I? I read somewhere, that you should wait a certain length of time to allow the H2O2 to boil of some, as not to damage the roots. Is 1.7ml per Liter a safe dose for immediate flooding?
Again, 1000 thanks Al !!!
