update for grow number 2........


i am at the second week of vegetation now and all plants really took off......i seperated the nft trays and placed 11&12 plants on each respectively......that nutrient from Cellmax called Rootbooster really boosts the root production.....most plants are now on the third set of real leaves and we are only 13 days from seed......
today i have placed the second 400hps unit into action.....two nft trays, 6 sqft each under 400 watts of hps each.....the plants theoretically should be ready for flowering by the end of this month but since they are all from standard seeds and i can't determine sex yet i am thinking to let them grow into vegetation up until the mid of september or up until they reach 45cm/18inches of height......what do you think i should do?
also, i have started monitoring the pH&EC levels every day and adjusting them when needed....
ph of today is 5.8 and EC 1.5......room temperature is stable @ 25 degrees celcius/77F
i plan to use some co2 enrichment by using yeast and sugar, unfortunately i am not able to buy anything yet (like co2 tabs) as the local suppliers are closed for vacations
