250 Dresser scrog
400w Circular Scrog
The ballast is switchable betweed mh and hps as you probaly already know.
Is a mh bulb during veg make that much of a difference in grow rate compared to hps all the way through?
I want to go with a rubbermaid DWC. What volume container would support 1 fully grown plants for lets say 5 days with no supervision and no topping up of the res?
I am either going to go with individual buckets or a single large plastic tote or a combo of a few small ones to best match the layout of the dresser i find.
What should the cfm of a fan be per cubic feet of the box? Like how often should the air be exchanging? |
well a mh has less lumens than an hps, youll prob have faster growth w/ hps, but i perfer to stick w/ how plants are suppose to use light, mh for veg, & hps for budding. i think youll have a better lookin & healthier plant useing the correct light for the dif stages of growth, if u where useing fem seed id say use hps all the way through, if reg seed go the right way (blue light (mh) is supposed to give u a better female ratio, maybe a myth). to leave a plant for 5 days w/ no supervision really doesnt matter what container size, as long as its big enough to supply the plant w/ water/nutes for 5 days, your best bet is a bubble bucket @ least 2gal. the rule of thumb is 1gal container per 1ft of plant, ex: 3ft tall plant = 3gal pot, most bubble buckets are 5gals. the cfm of the fan should match or double the cft of space & id leave it on while the lights are on, or all the time, & off when useing co2
