Sexing Plants

[Weasel]

I am new to hydro. I germinated my big bud and white lady seeds last week. They are appro 1 inch tall so far in rockwool cubes, just starting to grow 2nd set of leaves. Just wondering when I can sex them and at what stage it's any use using a feminiser spray??

cheers

u will see pistols anywhere from 2.5-3 weeks onwards and what type of femanize spray were u looking at using?

[Weasel]

thanks for the speedy reply.

Product I got with my gear was "La Femme" ( 5g/L NAA).

Are these sorts of products effective in general?

[Gazza2001au]

there are two types of femanizers the first one the seeds can be soaked for a more female batch or the plants can be sparyed as there growing to turn female the second type is just a pollen knock off for hermi'ed plants i dont have any experience with la femme but check out these links

thought i'd upload some pics of the seedlings. Again I'm new to all this, so any advice would be appreciated. I have just gleaned a little info from the web etc.

For the propagation tank : 25% nute solution,have a 50L tub, 100mm air disc, 150watt heater set on 25 degrees, seedlings in rockwool cubes, twin fluoro on top.

Stems seem spindly and 1st leaves seem to be ok sometimes then othertimes seem droopy. Is the humidity too high, do I not have the light close enough etc etc etc.

feminizer spray/soaking products can work, but you'll be far better off ripping out the males and keeping the best female to continue growing...it will also save you money as you wont have to buy the spray/soaking shit

 

but to get back on track, you wont be able to tell the sex of those plants for 2-3 weeks at the earliest and that would only happen if you put the plants under 12/12 right now which i so dont recommend. what i recommend is vegging those plants for another 2-3 weeks and then taking 2+ cuttings from each plant. as long as you label the plants and clones, you can flower the original plants to determine their sex while the clones are rooting and then rip out all the males, including the clones to ensure that you are growing only females from there its just a matter of keeping an eye out for any hermies and you'll never have to buy any of those spray/soak products and you'll be assured of a 100% seedless crop

thanks for the advice, it appreciated. I will certainly give that a go.

Seedlings are looking sick this morning so I really don't know what to do.... may have to start over again.

[Gazza2001au]

get rid of all the water in the bottom of the tub or atlease lower the level that is probably why ur seedlings are looking sick there main root has reached the water and arnt liking it and the cubes could be to wet

[bongonaussie]

Im with Gazza..get rid of the water..

 

also Id open up the side vents to let a bit of air flow..Im no expert with seeds...I tend to stick with clones in rockwool these days..

 

good luck with them, Weasel..

 

BTW, I love your name...That is a nickname I have for my eldest grand daughter..

Thanks guys. Have taken out the water.

Some silly person told me the bottom of the cubes should be sitting in the water... it looks like that's a complete load...

I hope they are not too far gone, poor pets.

 

Thanks bongonaussie - Weasel is what has become of my first name 'louise'...
