how is the heat from the t5's compared to the t12's? i am considering upgrading when i restart my grow but if i have to upgrade my ventillation with t5's i'll just stick with the t12's. they were plenty for my needs anyway, it's just that i always want to get new "toys" to mess around with. what strains do you have? i have seeds from my ww's, gypsy's kiss (reeferman) and master kush and ice from nirvana so i will be able to start back up where i left off.
