Hey there I've just looked over your threads and noticed a few things u could be doing better. First off what nutes are you using and how are u mixing? Second why are you adding h202??

You're growing using hydroponics if you have net pots suspended into the nutrients with an airstone and airpump in the res. Aeroponics is when you spray the nutrient solution on the roots and the excess drains back into the res anyhow... the perlite was a shitty idea they are fine with the hydroton like that and the foil on top of your res is pretty much useless as well u can chuck that out if you want. Don't be as paranoid of light as these people have made it out to seem but now you dont want be growing in a clear container...

Now these are all seeds so some will be male and some will be female.. u ahve them all in the same res so roots are going to grow together and you gotta watch for males and cut them down and throw them out asap or else they will pollinate your females and ruin your entire crop Also they are all different sizes and that is going to be a nightmare during flowering as the larger ones will block all light from the smaller ones and also the smaller plants don't need as strong nutes as the bigger ones....

I've never heard of anyone doing 19/5 light cycle either.. either go 24/0 or 18/6 I go 18/6 personally myself and use flouros for vegging and a 1000watt HPS for flowering. You made the right call in using your 400 Watt HPS and I would continure to use that for veg and flowering and take your Mercury Vapour light and throw it against a wall or something..When you do switch to flower just do it instantly no need to do anything gradually like you planned.. go 18/6 and the day you want to flower go 12/12 just like that it will not hurt your plants in anyway.

You said you are using tap water now what is the ppm of your tap water?? What are you using to adjust pH and how often are you adjusting it and how often are you doing res changes?

Let me know some of this info and I can teach you everything you need to know... alot of these idiots aren't really helping you!
Radium Reviewed by Radium on . Hydro White Widow Grow Heres some pics from my hydro white widow grow...Alot of the details can be found in basic growing under "growing the widow". They are all about 3 1/2 weeks from seed, some sprouted really late hence the size difference. Is the growth on track and do they look good? Oh and the burn on the leaves is from spilled nute/water mix I believe. Rating: 5
