Pythoff Plus™

Eliminates Toxic Build-Up in Hydroponic Systems

  • Maintains the condition of nutrient solutions — Prevents blocked drippers and accumulation of nutrient by-products
  • Enhances the weekly ‘flush’ — Restores the condition of the rootzone, medium and hardware
  • Maintains ‘stored’ water (RO and rain water) used for making nutrient solutions — Maintains its condition to prevent contamination of the working nutrient solution
  • Improves post-harvest system clean-up — Restores system hardware AND ‘recyclable’ mediums to avoid contaminating the next crop
  • Pythoff PLUS™ is 'standardized' to a specific concentration and has a shelf-life of 10 yrs plus — This ensures the correct dosage is applied. Note, underdosing is ineffective and overdosing can harm roots.
    Note: Competing products are generally highly unstable and therefore yield an inconsistent dosage
  • Safe to use from seed to harvest — gentle on roots

Nutrient solutions, flush water & stored water: 0.5ml/L (2ml/Gal)

Nutrient Management

Poor growth is often due to the failure to maintain the condition of the nutrient solution and root zone. FloraMax Pythoff PLUS is ideal for this as it is fully compatible with our organic additives – NOTE, regular chlorines and hydrogen peroxide can destroy the organics in FloraMax and many other nutrient products!  Also, any water that is stored for more than 2-3 days should be dosed with Pythoff PLUS (2ml/Gal or 0.5ml/L), then stored in the dark for at least 24 hours prior to use in a hydroponic system.

Directions & FAQs

The optimum dose rate depends on the condition of the nutrient system.  The regular dose rates are optimum for relatively clean/uncontaminated systems. If the system is very dirty, it is worthwhile increasing the dose rate by 50-100%.  Although this can cause root burning, it is generally worth the risk and roots will normally recover quickly once dosing is reduced. NOTE, for sensitive plants such as lettuce, the regular rate may be too high and as such, the regular rate may need to be halved.

Best start by doing a system flush: Once the nutrient reservoir is empty, do as much manual cleaning as possible then fill the reservoir with clean water and add Pythoff PLUS at 0.5ml/L (2ml/Gal). Adjust pH to between 5.0 and 7.0 then aim to flush for at least 1 hour. Ensure to run the nutrient pump regularly to improve the flushing of roots and hardware surfaces.  If the threat level is high, dump the initial flush water after about 1 hour then repeat the flush procedure. This process can be repeated every few days if problems are persisting.

After flushing, make a fresh batch of nutrient solution, however, ensure to add Pythoff PLUS to the water at 0.5ml/L (2ml/Gal) prior to adding nutrient and additives.  For recirculating systems, re-dose the existing nutrient solution *every 1-2 days* – NOTE, weekly dosing is unlikely to cure root browning.  For run-to-waste systems, re-dose every 3-4 days.  NOTE, when redosing *existing* nutrient solutions, ensure to predilute the Pythoff PLUS dose at least 10-fold (see FAQ on this) with raw water before adding to the reservoir.

STEP 1. Employ Pythoff PLUS in the “weekly” system flush: Once the nutrient reservoir has been drained fully, do as much manual cleaning as possible, then fill reservoir with clean water and add Pythoff PLUS at 0.5ml/L (2ml/Gal). Adjust pH to between 5.0 and 7.0 then aim to flush for at least 1 hour. Ensure to run the nutrient pump regularly to improve the flushing of roots and hardware surfaces.

STEP 2. Employ Pythoff PLUS in the nutrient solution:  After flushing, make a fresh batch of nutrient solution, however, ensure to add Pythoff PLUS to the water at 0.5ml/L (2ml/Gal) prior to adding nutrient and additives. As a general rule, the working nutrient should then be re-dosed after 7-days, however, for best results (!) ensure to predilute the Pythoff PLUS dose at least 10-fold with raw water before adding to the reservoir.  Obviously for shorter batch durations, as often used in run-to-waste systems, it will only be necessary to dose once (when the nutrient is made). If fanatical about using beneficial bacteria or myco’s then do NOT use Pythoff PLUS in the nutrient solution, use System Maintenance instead (1-2ml/L) (4-8ml/Gal).  However, if root browning problems do occur then the best course of action is to cease use of beneficial bacteria/myco’s and employ Pythoff PLUS instead.  Based on our experience, most bacteria/myco users follow this path and stay with Pythoff PLUS.

 

This means add 10ml of plain water for EVERY 1ml of Pythoff PLUS. For example, for a 100L reservoir, a 50ml Pythoff PLUS dose (0.5ml/L) needs to be diluted with 500ml of water. This dilution instruction is necessary to obtain optimum performance from Pythoff PLUS.

Also, aggressively stir the nutrient when adding the Pythoff PLUS/water mixture.  Never add undiluted Pythoff PLUS to existing nutrient. Although this will not harm the plants, it will reduce product performance.

Add Pythoff PLUS to a dedicated, stock reservoir at 50ml/L in clean water. Cover the reservoir to prevent ALL light ingress (important!). Replenish this solution monthly.  Set Doser to 1%.  Do NOT over-dose i.e. ensure the doser is accurate, reliable and capable of handling the solution.  Note, EPDM seals are ideal; Viton is usually suitable.

Dose when the nutrient batch is first made and always add Pythoff PLUS before any nutrient or additives are added – VERY IMPORTANT.  As a general rule, the working nutrient should then be re-dosed after 7-days, however, for best results (!) ensure to predilute the Pythoff PLUS dose at least 10-fold with raw water before adding to the reservoir.  Obviously for shorter batch durations, as often used in run-to-waste systems, it will only be necessary to dose once (when the nutrient is made).

Dirty or contaminated system should be re-dosed more regularly:  For recirculating systems, re-dose the nutrient solution every 1-2 days;  For run-to-waste systems, re-dose every 3-4 days.  Ensure to predilute the Pythoff PLUS dose at least 10-fold with raw water before adding to the reservoir and stir aggressively while adding this mixture.

 

Pythoff PLUS is much more powerful than System Maintenance and is therefore the recommended “preventative” measure for hydroponic systems.  However, unlike System Maintenance, it is NOT compatible with beneficial bacteria.  Therefore, if you deem beneficials as being critical (?), then it will be necessary to use System Maintenance for maintaining the condition of working nutrient solutions.  However, note, we definitely recommend using Pythoff PLUS for all other applications i.e. treating both ‘flush’ water and ‘stored’ water, and post-harvest system clean-up.

  1. Pythoff PLUS contains a de-scaler which prevents and removes the calcium scale that causes blocked drippers e.g. calcium carbonate and calcium sulfate.
  2. Very gentle on roots.
  3. Is far more stable in solution and therefore active for much longer – approx. 7-days.
  4. Pythoff PLUS is “standardized” to a specific concentration and has a shelf-stability of 10 yrs plus – competing products are generally highly unstable and yield an untrustworthy dosage!  Having the correct dosage is critical – underdosing will provide nil benefit, and overdosing will harm root hairs.
  5. Pythoff PLUS is fully compatible with all of the FloraMax organic additives.

Remove plants then partly fill reservoir with water.  Add 2-4ml/L (8-15ml/Gal) Pythoff PLUS, ensure pH 5 – 6.  Run pump hourly for 24-hours. Discard this solution then flush several times with fresh water.  To wash floors and walls and remaining hardware, spray with 25ml/L (100ml/Gal) FloraMax System Maintenance.  Scrub well then wait 30 minutes before rinsing clean with water

“I was having a problem with my root browning due to excess temps in my grow room. I had tried hydrogen peroxide to help kill any bacteria that had started to grow since my a/c went out and my temps were hitting over a hundred (Fahrenheit). I ordered some Pythoff and within two weeks I had new root growth. They were fresh white and firm little roots, something hydrogen peroxide could not accomplish”

“I was able to rescue some rare mother plant DNA. One important specimen, the last of its sort in my collection, was severely damaged and very nearly died going completely yellow and having leaves go brown and crispy. Pythoff is directly attributable to the rescue”

Ben C.

Grower — Bristol, United Kingdom

“No more do I see signs of bad stuff in the tanks i.e. clouds of white slimy gack floating in the tanks and collecting on the air stone. Plants are now just scorching along”

James S.

“I had chronic problems with root diseases damaging and killing my plants. Now I find that not only has the damage ceased, but even seriously badly damaged plants can be regenerated”

Oliver W.

Commercial Grower — Yuba City, California

“Flushed DWC system for 1.5 hours with Pythoff PLUS and cleaned it up, now roots are white again. I can’t believe how dense flowers are colas are joined extremly long and stems are like tree trunks, was using ***** for years, and now transitioned to Floramax. Much denser more terpenes and resin production”
