What does S1 strain mean?
When this pollen in used on the female flowers of the same plant or a clone from the same mother, the resulting seeds will be “selfed” or coined as S1. Breeders often do this to preserve the genetics of the strain, and to feminize the seeds.
Are F2 seeds stable?
F2 is a cross of 2 of your F1 plants from the seeds you bred. F2 is what true breeders are looking for. The F2 seeds are unstable meaning the plants grown can show very different qualities, some may be good while others are bad.

When should I start spraying STS?
-The spraying process begins the day before you switch the reversal plant(s) to flower. This should be done soon after the lights go off or soon after dusk for outdoor plants. Spray the nodal areas, and branches and tops. It is not necessary to spray the entire plant and all of the leaves.
How do you make and use silver thiosulfate solution STS?
Prepare a 0.02 M STS by slowly pouring 20 ml of 0.1 M silver nitrate stock solution into 80 ml of 0.1 M sodium thiosulfate stock solution. The STS can be stored in the refrigerator for up to a month. However, preparation of the STS just prior to use is recommended.
How do I get silver thiosulfate?
Prepare as follows: Prepare 0.02M (20mM) Silver Thiosulfate by adding 20 mL 0.1 M silver nitrate into 80 mL 0.1M sodium thiosulfate (or amounts in ration of 4 parts thiosulfate solution to 1 part silver nitrate solution). Store up to 30 days refrigerated (best to use fresh each time). Store in the dark.
How often do you spray STS?
Spray Every 5 Days All over the internet you’ll see people recommending spraying a plant and tossing it in flower and only a few say to spray it again after 2 weeks. The rest of the horticultural world says STS is effective for about 5 days in a plant.
How do I use silver thiosulfate?
Add your Silver Thiosulfate to 400ml of distilled water, so you’ll have around 450ml of STS. Make sure to shake quite a lot until it’s completely mixed. It’s still much too concentrated to apply straight onto your plants; take 100ml of the mixture you just made and add it to 400ml mor of distilled water.
What does silver thiosulfate do?
Silver Thiosulfate (STS) is commonly used to block the action of ethylene in plant cell cultures. Ethylene is a hormone that is present in the gaseous state. Ethylene increases during senescence and ripening, and has been shown to increase in plant cell cultures due to wounding or the presence of auxins.
Is silver thiosulfate safe?
silver thiosulfate is more technique sensitive but is applied once every 5 days. so more work and caustic chemicals, precisely measured up front but the only reapplied every 5 days for 30 days. Colloidal silver can be made using electrolysis (i need to study the process) with pure silver, cheaply and safely.
What is s2o3 2 called?
Molecular Formula. O3S2-2. Synonyms. Thiosulphate. THIOSULFATE ION.
Is silver thiosulfate soluble?
Silver thiosulphate, Ag2S2O. Precipitation of a solution of sodium thiosulphate with Silver nitrate yields the Silver thiosulphate, Ag2S2O3, as a white precipitate of sweetish taste. It dissolves in solutions of other thiosulphates, forming double salts.
What will dissolve silver chloride?
Silver chloride, however, is insoluble in water, which means a white solid of AgCl crystals will form in the resulting solution. The full dissolution of silver requires nitric acid, or HNO3, which reacts with silver to form silver nitrate, a water-soluble compound.
What happens when a dilute solution of sodium thiosulphate is treated with silver nitrate?
Hint: Aqueous hypo solution is a chemical compound known as sodium thiosulphate which is pentahydrate and either white or colourless. It reacts with silver nitrate to form a white precipitate which further dissolves in excess hypo solution to produce a black precipitate of silver sulphide.
How do you get silver out of silver chloride?
To convert silver chlorides to metallic silver you will need to use dry caustic soda (sodium hydroxide)and dextrose (corn syrup can be used). Rinse the silver chlorides well with water to remove any residual copper.
How do you purify AgCl?
Acidification after filtration with nitric or hydrochloric acid will return the silver chloride. Recall that a blue colour indicates copper contamination. Assuming you just want pure silver from your AgCl, you’re best off to add some more base (i.e. NaOH) and reduce with a suitable reducing sugar, namely dextrose.
What happens when you burn silver chloride?
Silver chloride is a chemical compound with the chemical formula AgCl. Upon illumination or heating, silver chloride converts to silver (and chlorine), which is signaled by grey to black or purplish coloration to some samples. AgCl occurs naturally as a mineral chlorargyrite.
Can silver chloride be melted?
Silver chloride melts at a temperature of 455° C and boils at 1550° C. It is one of the few chloride compounds known to be very insoluble in water. Only PbCl2 and Hg2CL2 share this unique property, with PbCl2 being soluble in hot water. A prime example of this is the use of AgCl-Mg batteries for submarine torpedoes.
Are S1 seeds female?
S1, feminised cannabis seeds The acronym S1 refers to the first filial generation produced as a result of crossing the plant with itself. This is achieved by a range of techniques aimed at reversing the sex of the selected female plant, getting it to produce male pollen and using it to pollinate itself.
Are F1 seeds better?
None will be as vigorous and productive as their parent. An F1 is not a ‘pure line’ and stable. It contains genes from both parents and how these will combine in the offspring is a matter of random chance. There is no benefit for the home grower in saving seed from F1 Hybrids.
Is F1 dog better than F2?
When it comes to the small or tiny designer dog breeds, health problems are more likely to occur than they are with the larger breeds. An F1 (first generation) Labradoodle or Goldendoodle can have a lab like coat that sheds, an F2 is more likely to have a hypoallergenic, low to non-shed coat.
