Thx for all these advices scorpion,,Hi Max,
a few questions for you,before I give a comment on Ortega.
1. what is the sq ft of your room?
2. what are the type and wattage of all lights used?
3. what is the maximum ambient temperature/humidity of your room.
4. ceiling to floor height?
Well Water is fine for plants if it is fine for human consumption,
one thing to watch for is Calcium Carbonate ,arsenic,heavy metals...
all of which can be removed or dramatically lowered with a quality carbon filter system or a compact RO system like the one I use.
MNS Ortega Indica has so far been a real pleasure to grow,
exceptional plants once a root ball is established
<THIS IS WHERE PEOPLE SCREW UP>
You are dealing with an Afghan Indica people!
STOP DROWNING the seedlings!
I bet at least as many seedling are root rotted than ever get grown to maturity.
Afghanistan is a dry desert climate,
not a tropical rain forest like Thailand or Columbia...
Remember this when growing Ortega/Nordle/Medman/Devil indoors.
once your seedlings have emerged...stop and think before watering that plant...
lift the pot,if it is heavy...leave it alone do not water.
Make the plant reach/search for the moisture and nutrient already in the soil.
put the planter in water catchments if they do not already have a water well under the pot.
Water from the bottom,let the plant suck up the moisture from the bottom.
This will guarantee a solid well established root ball...
Going into bloom.
IT DONT MATTER HOW YOU DO IT...
I usually go 18-6...transition with 24 lights off...then start up with 12on 12 off...
the plant will TRIGGER when it has recieved the right amount of darkness for that individual plant.
Ortega is very uniform and the seedlings look like clones
so hey Shantibaba did it right AGAIN.
Dont roast the seedling by placeing them took close to the lamp.
How close is too close?
Well place your hand under the lamp...you tell me how close is too close.
Common Sense is an amaizing thing !
If you go into your room and it is stuffy,damp,hot...
Then you have NO exhaust ventilation...Move the air .
A well designed grow room is a nice place to be on a hot day or a cold day .
if it is hot for you then it is hot for the plants too.
OK I guess that is all I will say,it should be plenty.
However ventilation, soil being aerated and well drained and most of what is written above is worth for all cannabis strains and not only for the Ortega variety but thx for your comment.
