I am a first time grower in the southeast us. I am a contractor so getting materials and general knowledge of how to engineer things together and making it work is what i do for a living so i have had a little fun prepping for this. i am starting out with a 4x4 grow box made out of OSB. i am going to start 4 plants with a 150w MH and 8 cfls (only 4 in the pic). i am also waiting on my HTG order with 600 w HPS for flower and reflective mylar and foxfarm nutes. i am using fox farm ocean for medium.
i want to master lst to maximize my space in this box. i have some lighting questions. keeping that in mind should i keep all of the lights over head or is having the cfl's on the sides as pictured a better method? Also should i hang the MH so it will be closer to the plants and raise it as needed? When should i start flowering in a 4' space?
also the grow space is in an attic and temperatures are going to be an issue. it is really cold there now and will be really hot in the summer. i have a small 1500w space heater that works ok but i would rather not use it because of the energy consumption. but i think i am going to have to at least until the 600w hps is putting out enough heat on its own. i was thinking of insulating the roof to keep the heat out in the summer but i dont think it would really help that much in the winter. the 600w light has an air cooled hood and i will be venting that outside in the summer but any temperature suggestions that are affordable would be much appreciated. i have already ran a dedicated 20a circuit up to the space so thats not a really big issue. i figure about 2000w per 20a breaker is acceptable. i just hope i dont have to run the heater and 600w hps at the same time.
any questions, tips, or advice would be very much appreciated.
